  • 00:00:00 - 00:05:00

    Nvidia a annoncé la série GeForce 50 et la technologie DLSS 4 au CES 2025. Les nouveaux modèles incluent les RTX 5090, 580, 570 TI et 570, avec les 580 et 590 disponibles dès le 30 janvier. La RTX 590 présente une augmentation significative du matériel par rapport à la génération précédente, incluant une nouvelle architecture Blackwell, plus de cœurs CUDA et une bande passante mémoire supérieure. Les modèles varient en taille et en puissance, avec des configurations mémoire et des capacités de VRAM différentes.

  • 00:05:00 - 00:10:00

    Le rapport qualité-prix des GPU Blackwell a été discuté, la RTX 5090 étant extrêmement chère à 2000 USD, tandis que la 580 est à 1000 USD. Les modèles 570 TI et 570 coûtent respectivement 750 USD et 550 USD, soit 50 USD de moins que leurs prédécesseurs. Nvidia utilisez le DLSS 4 pour justifier de meilleures performances, prétendant que les GPU de la série 50 génèrent deux fois plus d'images. Cependant, ces gains ne se traduisent pas toujours par une amélioration de la latence et de la sensation de jeu.

  • 00:10:00 - 00:15:00

    La nouvelle architecture Blackwell améliore l'intégration des cœurs tenseurs et des unités de traçage de rayons, promettant une meilleure efficacité et compression pour réduire l'empreinte mémoire. Même si les performances d'encodage et de décodage vidéo sont améliorées, l'évolution ne permet pas d'estimer précisément le vrai gain de performance par rapport aux générations précédentes. Nvidia a également mis en avant des améliorations en technologie de moniteur, supportant des configurations multi-écrans avancées sans compression de flux.

  • 00:15:00 - 00:24:18

    Enfin, Nvidia a lancé DLSS 4, introduisant le multigénération de trame pour augmenter le nombre d'images affichées, soulevant des questions quant à la qualité des images générées et la latence. DLSS 4 inclut des améliorations d'images grâce à l'utilisation de Transformers, augmentant la stabilité temporelle et réduisant le flou. Des dizaines de jeux sont attendus avec le support de DLSS 4, une avancée significative pour l'adoption par les développeurs. Toutefois, la dépendance au multigénération questionne quant à l'impact sur l'expérience de jeu.

  • 00:00:05
    Nvidia has just announced the GeForce 50
  • 00:00:08
    Series and dlss 4 technology I'm sure
  • 00:00:10
    many of you were watching the live
  • 00:00:11
    stream so it's time to give my thoughts
  • 00:00:13
    on what has been shown right here at CES
  • 00:00:16
    2025 in addition to all the specs
  • 00:00:18
    pricing performance claims and there was
  • 00:00:20
    even a lot of stuff that wasn't in that
  • 00:00:22
    live stream that you might have missed
  • 00:00:24
    as expected Nvidia focused on high-end
  • 00:00:26
    models for this launch announcing the
  • 00:00:28
    GeForce RTX 5090 the RTX 580 the RTX 570
  • 00:00:33
    TI and RTX 570 and it won't be long
  • 00:00:36
    until you can get your hands on one with
  • 00:00:38
    the RTX 580 and 590 launching first on
  • 00:00:41
    January 30th this will be followed by
  • 00:00:43
    the RTX 570 and 570 TI in February with
  • 00:00:47
    more 50 Series models coming later I'm
  • 00:00:49
    assuming 50 60s that sort of thing will
  • 00:00:51
    be announced down the track the flagship
  • 00:00:53
    model the RTX 590 packs a significant
  • 00:00:56
    increase in Hardware over its
  • 00:00:57
    predecessor the RTX 490 not only does
  • 00:01:01
    this GPU use nvidia's new Blackwell
  • 00:01:03
    architecture it also packs significantly
  • 00:01:05
    more cuticles more memory bandwidth and
  • 00:01:07
    a higher vram capacity the SM count has
  • 00:01:10
    increased from 128 with the 490 to a
  • 00:01:13
    whopping 170 with the RTX 590 a 33%
  • 00:01:17
    increase in the size of the core but
  • 00:01:20
    there's decreased GPU clocks going from
  • 00:01:22
    a boost of 2.5 GHz down to 2.4 GHz now
  • 00:01:26
    the memory subsystem is overhauled Now
  • 00:01:28
    featuring gddr 7ch technology on a huge
  • 00:01:31
    512-bit bus with this gddr 7 memory
  • 00:01:34
    clocked at 28 gbits per second memory
  • 00:01:37
    bandwidth comes out to
  • 00:01:39
    1,792 GB per second and the 80% increase
  • 00:01:43
    on the 409s bandwidth this is attached
  • 00:01:45
    to 32 gig of vram as well the most
  • 00:01:47
    Nvidia have provided on a consumer GPU
  • 00:01:50
    with consumer Blackwell still built on
  • 00:01:52
    tsmc 4 NM technology the board power
  • 00:01:54
    rating has risen to accommodate these
  • 00:01:56
    cores and memory rising to a mammoth 5
  • 00:02:00
    75 wats 28% higher than the 490 the RTX
  • 00:02:03
    580 uses a much smaller GPU
  • 00:02:06
    configuration in fact an entirely
  • 00:02:08
    different GPU die with just 84 SMS four
  • 00:02:11
    more than last gen's RTX 480 super
  • 00:02:14
    pretty much everything about this model
  • 00:02:15
    is half of the RTX 590 just under half
  • 00:02:18
    the Cuda cores half the memory bus width
  • 00:02:21
    to 256 bits half the vram capacity at
  • 00:02:24
    just 16 GB a little over half the memory
  • 00:02:26
    bandwidth at 960 GB per second through
  • 00:02:29
    the use of gddr 7 clocked at 30 GB per
  • 00:02:32
    second normally this is the
  • 00:02:34
    configuration you'd get with an RTX 5070
  • 00:02:37
    type of GPU which is historically where
  • 00:02:39
    Nvidia have positioned the model that's
  • 00:02:41
    half the size of the flagship but these
  • 00:02:42
    days it's a 80 in I guess a bit of a
  • 00:02:45
    disappointing move for gamers the RTX 57
  • 00:02:48
    TI is cut down further it falls to 70 SM
  • 00:02:50
    4 SM more than the last Generations 47
  • 00:02:54
    super however boost clocks are down from
  • 00:02:56
    2.61 GHz to 2.45 GHz now the memory bus
  • 00:03:00
    width Remains the Same as the RTX 580
  • 00:03:02
    256bit meaning it also has 16 GB of gddr
  • 00:03:06
    7 memory this time it's 28 GB per second
  • 00:03:08
    memory leading to 896 GB of bandwidth
  • 00:03:12
    the 570 TI is rated at 300 wats while
  • 00:03:14
    the 580 is rated at 360 WS then there's
  • 00:03:18
    the RTX 570 we're looking at 48 SMS here
  • 00:03:21
    which is just 2 sms more than the RTX
  • 00:03:23
    470 from the previous generation it also
  • 00:03:26
    has just a 192-bit memory bus and 12 GB
  • 00:03:29
    vram which I think is insufficient for
  • 00:03:32
    this tier of product in 2025 boost
  • 00:03:34
    clocks are only slightly higher than the
  • 00:03:36
    4070 and there's a total power rating of
  • 00:03:39
    250 wat all new GeForce 50 Series gpus
  • 00:03:42
    come with new connectivity including PCI
  • 00:03:44

    for more information please check the
  • 00:04:59
    links in the video description now let's
  • 00:05:01
    talk about the most important aspect of
  • 00:05:03
    Blackwell its price performance and
  • 00:05:06
    price to Performance ratio there's some
  • 00:05:08
    good stuff and some bad stuff in here
  • 00:05:10
    the GeForce RTX 590 is disgustingly
  • 00:05:12
    expensive as many people expected priced
  • 00:05:15
    at $2,000 us however the RTX 580 with
  • 00:05:19
    half the GPU Hardware is priced at
  • 00:05:21
    $1,000 us which is less ridiculous than
  • 00:05:24
    many of the rumors were expecting but
  • 00:05:26
    obviously still quite expensive I think
  • 00:05:28
    the surprises for me were the 570 TI
  • 00:05:30
    priced at
  • 00:05:32
    $750 and the 570 priced at
  • 00:05:35
    $550 both $50 lower than the same models
  • 00:05:38
    at launch in the previous generation for
  • 00:05:41
    performance claims Nvidia are using a
  • 00:05:42
    lot of their usual BS to obfuscate
  • 00:05:45
    actual gaming performance because RTX 50
  • 00:05:47
    gpus support dlss 4 multiframe
  • 00:05:50
    generation whereas RTX 40 gpus do not so
  • 00:05:54
    RTX 50 Series gpus are capable of
  • 00:05:56
    creating double the amount of frames
  • 00:05:58
    that previous gen models can
  • 00:06:00
    meaning any dlss supported games could
  • 00:06:02
    instantly be up to twice as fast on a 50
  • 00:06:06
    Series GPU than a 40 series GPU if we're
  • 00:06:09
    talking about DS S4 games and I'm using
  • 00:06:11
    air quotes here because the FPS number
  • 00:06:14
    will go up with dss4 but not necessarily
  • 00:06:16
    the latency and feel of the game that we
  • 00:06:18
    normally associate with performance in
  • 00:06:21
    the charts we did get Nvidia showed four
  • 00:06:24
    games and apps supporting dss4 cyberpunk
  • 00:06:26
    277 Allen Wave 2 Blackmouth Wukong and
  • 00:06:29
    called D5 render so I'll ignore those
  • 00:06:32
    because we have no idea how those games
  • 00:06:34
    actually perform in an Apples to Apples
  • 00:06:36
    sort of scenario so it's the other games
  • 00:06:38
    that matter immediately this makes the
  • 00:06:40
    claim that the RTX 5070 matches the RTX
  • 00:06:43
    490 in performance highly dubious
  • 00:06:46
    probably wrong most of the time Asar
  • 00:06:48
    claims it's twice as fast as a 4070
  • 00:06:51
    that's just not going to happen across
  • 00:06:53
    most games maybe you'll get that in
  • 00:06:55
    terms of frame rate when using dss4 but
  • 00:06:58
    certainly not when decide not to use
  • 00:07:00
    frame generation in some of the examples
  • 00:07:02
    the 5070 is around 20 to 30% faster than
  • 00:07:05
    the 4070 at 1440p when we do not include
  • 00:07:09
    multiframe generation this would make
  • 00:07:11
    the RTX 5070 a little faster than the
  • 00:07:13
    4070 super for about $50 less or
  • 00:07:16
    alternatively 20 to 30% faster than the
  • 00:07:18
    4070 at the same price depending on how
  • 00:07:21
    it Stacks up to the 470 super this could
  • 00:07:23
    be a reasonable though a little
  • 00:07:25
    underwhelming GPU 10% faster than the
  • 00:07:27
    470 super and around 9% % cheaper would
  • 00:07:30
    be a roughly 20% Improvement in cost per
  • 00:07:33
    frame Nvidia made similar claims for the
  • 00:07:35
    RTX 570 TI versus the 47 ETI at 1440p
  • 00:07:39
    somewhere in the 20 to 30% performance
  • 00:07:42
    Improvement range if we ignore
  • 00:07:43
    misleading deals S4 numbers those
  • 00:07:46
    numbers would be reduced a bit compared
  • 00:07:48
    to the 470 TI super which is 10% faster
  • 00:07:51
    than a 470 TI as it's $50 cheaper than
  • 00:07:54
    those gpus we're looking at a decent
  • 00:07:56
    cost per frame increase than the 470 TI
  • 00:07:59
    likely over 30% if nvidia's numbers are
  • 00:08:01
    accurate but that will fall back closer
  • 00:08:03
    to 20% relative to the newer 470 TI
  • 00:08:05
    super which was the much better graphics
  • 00:08:08
    card similar stuff for the RTX 580
  • 00:08:11
    relative to the RTX 480 around 20 to 30%
  • 00:08:14
    faster in those non dss4 games and given
  • 00:08:16
    the 480 super was only about 5% faster
  • 00:08:18
    than the 480 we're again going to get
  • 00:08:20
    about a 20% increase in cost per frame
  • 00:08:23
    going on nvidia's NDS S4 numbers it's
  • 00:08:26
    hard to get a good read on the
  • 00:08:27
    performance of the RTX 50 9 again the
  • 00:08:30
    non-dealers S4 numbers show a pretty
  • 00:08:32
    underwhelming gain 20 to 40% relative to
  • 00:08:35
    the RTX 490 the 90 is 25% more expensive
  • 00:08:39
    than the 490 so you'd want most games to
  • 00:08:41
    be closer to a 50% gain to get around a
  • 00:08:44
    20% Improvement in cost per frame
  • 00:08:47
    however nvidia's testing was done at 4K
  • 00:08:49
    using dlss performance mode in other
  • 00:08:52
    words rendering natively at 1080p I
  • 00:08:54
    suspect that feeding a GPU as huge as
  • 00:08:57
    the 5090 will be difficult at a 1080p
  • 00:08:59
    render resolution causing CPU
  • 00:09:02
    bottlenecks and underutilization of the
  • 00:09:04
    GPU in general this could be why we are
  • 00:09:06
    seeing more substantial improvements in
  • 00:09:08
    those path traced dss4 games relative to
  • 00:09:12
    the other RTX 50 Series gpus we've
  • 00:09:14
    looked at so far because I do expect
  • 00:09:16
    this card to be probably the largest
  • 00:09:18
    performance game gen over gen but to be
  • 00:09:20
    fair this could also be an issue for
  • 00:09:21
    gamers actually buying this GPU using
  • 00:09:24
    them in realistic conditions if you're
  • 00:09:25
    going to be playing at 1440p or 1080p
  • 00:09:27
    might be a bit harder to feed that GPU
  • 00:09:29
    so well as always we'll have to wait for
  • 00:09:31
    reviews to see how that plays out my gut
  • 00:09:34
    feel here and initial reaction is that
  • 00:09:35
    Nvidia seemed to be delivering around a
  • 00:09:37
    20% cost per frame Improvement and
  • 00:09:39
    therefore 20% value increase across the
  • 00:09:42
    board when comparing to RTX 40 super
  • 00:09:44
    gpus that is certainly better than the
  • 00:09:46
    RTX 40 series which in many situations
  • 00:09:49
    offered absolutely nothing for gamers in
  • 00:09:51
    terms of value but it also feels a bit
  • 00:09:54
    underwhelming when coming off such a bad
  • 00:09:56
    generation the value increase relative
  • 00:09:58
    to RTX 30 series gpus I think a lot of
  • 00:10:01
    people will be considering an upgrade
  • 00:10:02
    from that sort of GPU and if we compare
  • 00:10:04
    it to those gpus at the
  • 00:10:06
    MSRP the value increase isn't going to
  • 00:10:08
    be that large in many scenarios
  • 00:10:09
    considering it's a two Generation 4 and
  • 00:10:12
    a halfe step it's better than nothing
  • 00:10:15
    but to correct the Flop that was the RTX
  • 00:10:17
    40 series a value increase in the 30 to
  • 00:10:20
    40% range was probably needed 20% as it
  • 00:10:23
    stands is on the lower end of value
  • 00:10:25
    increases looking throughout nvidia's
  • 00:10:27
    history I don't want to critize ize it
  • 00:10:29
    too much because it could come down to
  • 00:10:31
    the actual margins and we don't have
  • 00:10:33
    enough performance data to go on right
  • 00:10:35
    now hopefully this apparent 20% value
  • 00:10:37
    increases more like 30% in reality in
  • 00:10:39
    which case this looks like a good
  • 00:10:41
    generation if the card's value Falls
  • 00:10:43
    closer to 20% or Worse even lower than
  • 00:10:45
    that it will be a disappointment but so
  • 00:10:48
    far there is enough to get at least a
  • 00:10:49
    little bit excited about and certainly
  • 00:10:51
    those prices aren't as horrendous as a
  • 00:10:53
    lot of people are expecting one of my
  • 00:10:55
    concerns with this generation is the
  • 00:10:57
    absolute Chasm Nvidia has created
  • 00:10:58
    between the highest tier model and the
  • 00:11:01
    next model down it's pretty absurd that
  • 00:11:03
    the RTX 5090 is basically double the
  • 00:11:06
    hardware of the RTX 580 it's almost like
  • 00:11:08
    we're back in the days of dual gpus
  • 00:11:11
    except this is a massive single GPU die
  • 00:11:14
    this makes the RTX 580 feel like quite a
  • 00:11:17
    weak product in comparison even though
  • 00:11:19
    there is a substantial price difference
  • 00:11:21
    to account for that gone of the days of
  • 00:11:23
    the ad0 class being just a small
  • 00:11:25
    reduction in capabilities relative to
  • 00:11:27
    the best model that Gap is growing
  • 00:11:30
    ensuring that gamers are forced to pay a
  • 00:11:32
    ludicrous amount of money to access
  • 00:11:34
    performance that's materially better
  • 00:11:36
    than the best of the 40 series this has
  • 00:11:38
    flowing effects for the rest of the
  • 00:11:40
    product stack which also become
  • 00:11:41
    comparatively weak relative to the best
  • 00:11:43
    GPU however there's at least some good
  • 00:11:45
    news here because in the previous
  • 00:11:47
    generation the 480 had 26% more cicor
  • 00:11:50
    than the 470 TI in this generation the
  • 00:11:52
    580 has 20% more criticals than the 570
  • 00:11:55
    TI as well as much closer memory specs
  • 00:11:58
    so the 570 TI isn't cut down as much
  • 00:12:00
    relative to the 5080 when compared to
  • 00:12:02
    what Nvidia was doing with the RTX 40
  • 00:12:05
    series launch let's move now to talking
  • 00:12:07
    about nvidia's Blackwell architecture
  • 00:12:09
    now this is an iteration on previous
  • 00:12:11
    architectures improving various aspects
  • 00:12:13
    that existed in previous generations
  • 00:12:15
    like rate tracing units and tensor
  • 00:12:17
    Nvidia spoke for a ridiculous amount of
  • 00:12:20
    time about AI so I won't bore you with
  • 00:12:23
    all that stuff but basically Blackwell
  • 00:12:25
    is powerful for AI in addition to
  • 00:12:27
    regular processing I know shocker and
  • 00:12:29
    new Nvidia gpus being advertised to be
  • 00:12:31
    the best for AI yet in more interesting
  • 00:12:34
    things the architecture has tighter
  • 00:12:35
    integration with the tensor cores inside
  • 00:12:37
    the SM improved Shader execution
  • 00:12:39
    reordering which is twice as efficient
  • 00:12:41
    and RT cores with twice the ray triangle
  • 00:12:44
    intersection rate and enhanced
  • 00:12:45
    compression to reduce the memory
  • 00:12:47
    footprint while rate tracing Nvidia
  • 00:12:49
    claims this will allow for more geometry
  • 00:12:51
    as well while R tracing Blackwell also
  • 00:12:53
    improves video encoding and decoding to
  • 00:12:55
    a new generation of the hardware engine
  • 00:12:57
    this is the first time we are getting a
  • 00:12:59
    video decoding engine Improvement since
  • 00:13:01
    the RTX 20 to 30 series upgrade the new
  • 00:13:04
    display engine is also much better and
  • 00:13:06
    allows for new multim monitor
  • 00:13:07
    configurations up to four 4K 165 HZ
  • 00:13:10
    monitors without DSC or 2 4K 360 HZ
  • 00:13:14
    monitors with DSC and of course various
  • 00:13:16
    combinations of those sorts of things
  • 00:13:17
    you can even do two 8K 100 HZ monitors
  • 00:13:20
    with dsse for example Nvidia are
  • 00:13:22
    releasing Founders editions for all the
  • 00:13:25
    models except the RTX 570 TI this Fe
  • 00:13:28
    model looks pretty similar to the 4090
  • 00:13:30
    FV cards in the general design except
  • 00:13:33
    now both fans are on the same side
  • 00:13:36
    amazingly Nvidia are using just a two-
  • 00:13:38
    slot design for the 5090 despite the
  • 00:13:40
    card being rated for 575 wats it'll be
  • 00:13:43
    very interesting to see how hot that
  • 00:13:44
    thing runs the RTX 580 appears to use a
  • 00:13:47
    very similar Founders Edition design
  • 00:13:49
    while the 5070 uses a scale down model
  • 00:13:52
    that isn't as long 242 mm long for that
  • 00:13:55
    version versus 304 mm for the higher
  • 00:13:58
    versions going on their spec
  • 00:14:00
    moving on to Features now and as part of
  • 00:14:02
    the presentation Nvidia announced dlss 4
  • 00:14:04
    the next generation of their upscaling
  • 00:14:06
    technology the headlining feature here
  • 00:14:08
    is frame generation with its ability to
  • 00:14:10
    generate three frames for every one real
  • 00:14:12
    frame now instead of generating one
  • 00:14:14
    frame for every one real frame I guess
  • 00:14:17
    this is something but let's be honest
  • 00:14:19
    there are significant question marks
  • 00:14:21
    here over latency and image quality when
  • 00:14:23
    generating one frame every second frame
  • 00:14:26
    50% of the time you were seeing a real
  • 00:14:28
    frame but when you're generating three
  • 00:14:30
    frames only 25% of the time you are
  • 00:14:33
    seeing a real frame 75% of the time it's
  • 00:14:35
    those generated frames so these
  • 00:14:37
    generator frames had better be amazing
  • 00:14:39
    quality otherwise you will see a ton of
  • 00:14:41
    artifacts a lot of the time something
  • 00:14:43
    that will be an issue unless the quality
  • 00:14:45
    of generated frames is significantly
  • 00:14:47
    overhauled relative to dss3 and they are
  • 00:14:50
    making some claims that it is the other
  • 00:14:52
    issue is using multiframe rendering to
  • 00:14:54
    hack our way to high frame rate gaming
  • 00:14:57
    in video showed a demo where without DLS
  • 00:14:59
    S 4 a gamer is running at 30 FPS but
  • 00:15:01
    then over 240 FPS with dss4 enabled now
  • 00:15:05
    of course not even dlss upscaling was
  • 00:15:07
    enabled in the 30fps example if you turn
  • 00:15:09
    on just upscaling the frame rate was
  • 00:15:12
    reasonable but I really don't want to
  • 00:15:13
    see any situations where generating
  • 00:15:15
    three frames is used to get a 30 FPS
  • 00:15:18
    game up to 120 FPS that would be
  • 00:15:20
    absolutely horrific in terms of input
  • 00:15:22
    latency dss4 is exclusive to Blackwell
  • 00:15:26
    gpus however only for this multiframe
  • 00:15:28
    rendering component deals SV also
  • 00:15:31
    features enhancements to regular frame
  • 00:15:33
    generation super resolution and Ray
  • 00:15:35
    reconstruction with the same support for
  • 00:15:37
    those features as we currently have the
  • 00:15:40
    restriction on multiframe rendering is
  • 00:15:42
    due to what Nvidia calls enhanced
  • 00:15:44
    Hardware flip metering capabilities in
  • 00:15:46
    the Blackwell architecture which moves
  • 00:15:48
    some of the things that were done on the
  • 00:15:50
    CPU for frame generation on the RTX 40
  • 00:15:52
    series into the GPU on Blackwell Nvidia
  • 00:15:55
    says this is required for a smooth
  • 00:15:57
    experience with this Tech which I hope
  • 00:15:59
    is true otherwise RTX 40 series owners
  • 00:16:01
    are getting screwed the quality
  • 00:16:03
    enhancements to upscaling and other
  • 00:16:04
    aspects to dss4 are significant
  • 00:16:06
    according to Nvidia thanks to the use of
  • 00:16:08
    what they say are Transformers Nvidia
  • 00:16:11
    claims this will improve image quality
  • 00:16:13
    with improved temporal stability less
  • 00:16:15
    ghosting and higher detail in motion
  • 00:16:18
    that sounds pretty exciting to me and
  • 00:16:19
    actually I'm more interested in the
  • 00:16:21
    upscaling quality improvements in DS S4
  • 00:16:24
    than multiframe rendering Nvidia also
  • 00:16:27
    say the new frame gen model is 40%
  • 00:16:29
    faster and uses 30% less vram for
  • 00:16:32
    generating multiple frames the AI
  • 00:16:34
    algorithm only needs to be run once per
  • 00:16:36
    rendered frame Optical flow in the frame
  • 00:16:38
    gen component is replaced with an
  • 00:16:40
    efficient AI Hardware model which throws
  • 00:16:42
    up questions as to why frame generation
  • 00:16:44
    is still exclusive to the 40 series
  • 00:16:46
    given it was Hardware restricted due to
  • 00:16:48
    Optical flow accelerators and a love
  • 00:16:50
    lace maybe that AI model could now run
  • 00:16:52
    on older gpus but no still restricted
  • 00:16:56
    what's not clear is whether the new
  • 00:16:57
    Transformer model for dlss has a
  • 00:16:59
    performance impact and whether this
  • 00:17:01
    performance impact is the same for all
  • 00:17:02
    gpus for example they claim frame
  • 00:17:04
    generation is now faster but is that on
  • 00:17:07
    both RTX 50 and RTX 40 gpus is there a
  • 00:17:10
    performance impact from using the trans
  • 00:17:12
    performer model for upscaling especially
  • 00:17:14
    on those lower tier cards many questions
  • 00:17:16
    to be answered in testing the fact that
  • 00:17:19
    75 games and apps are coming at launch
  • 00:17:21
    with dss4 support is quite impressive
  • 00:17:23
    showing Nvidia has learned that you need
  • 00:17:26
    widespread game support to make features
  • 00:17:28
    worthwhile I don't know if this means
  • 00:17:30
    there will be significant game updates
  • 00:17:31
    at launch for all of those Tiles at once
  • 00:17:33
    or whether Nvidia has found some way to
  • 00:17:35
    automatically add dss4 to those games
  • 00:17:37
    but a quick look through the list it
  • 00:17:38
    isn't every DS S3 game and some games
  • 00:17:41
    are only adding in DS S4 support later
  • 00:17:43
    so it does suggest a widespread effort
  • 00:17:46
    from game developers to add in this
  • 00:17:47
    feature in addition Nvidia are bundling
  • 00:17:50
    in an override feature in the Nvidia app
  • 00:17:52
    which will act like a dll swap allowing
  • 00:17:54
    upgrades or overrides as they call them
  • 00:17:57
    to the latest DSS models for frame
  • 00:17:59
    generation super resolution and Ray
  • 00:18:01
    reconstruction it will also allow frame
  • 00:18:03
    generation to turn into multiframe
  • 00:18:05
    generation for 50 Series owners Nvidia
  • 00:18:08
    has announced reflex 2 as well which is
  • 00:18:10
    essentially bringing frame warp from VR
  • 00:18:12
    Gaming to regular PC gaming for the
  • 00:18:15
    first time basically the idea here is
  • 00:18:17
    instead of showing the rendered frame
  • 00:18:19
    based on Old input reflex 2 will take a
  • 00:18:22
    more recent input sample do some
  • 00:18:25
    calculations on the CPU and warp / shift
  • 00:18:28
    the rendered frame
  • 00:18:29
    based on that input in a sense this
  • 00:18:32
    fakes a frame update and applies it to
  • 00:18:34
    the rendered frame reducing perceived
  • 00:18:36
    latency for actions that shift the
  • 00:18:38
    camera because real input is being taken
  • 00:18:41
    into account to warp the frame by the
  • 00:18:43
    correct amount it will not reduce
  • 00:18:45
    latency for game actions like firing
  • 00:18:47
    your gun for example because that cannot
  • 00:18:48
    be warped but for camera actions you get
  • 00:18:51
    I don't even know if faked is the right
  • 00:18:52
    word to use for that it it could reduce
  • 00:18:54
    latency if it works well it's a cool
  • 00:18:57
    concept I guess it remains to be seen
  • 00:18:58
    how it actually works in games is it
  • 00:19:00
    going to feel nice to play a game with
  • 00:19:02
    reflex 2 on or will it feel a bit floaty
  • 00:19:04
    and weird if the warp calculations
  • 00:19:06
    aren't quite right it's hard to say at
  • 00:19:08
    this point although it's good to see
  • 00:19:09
    Nvidia claiming gains for both CPU and
  • 00:19:11
    GPU limited scenarios because previous
  • 00:19:13
    versions of reflex didn't really do much
  • 00:19:15
    if you were CPU limited there's also the
  • 00:19:17
    question of image quality and while
  • 00:19:19
    Nvidia claimed they are using inpainting
  • 00:19:21
    to solve issues with gaps in the Warped
  • 00:19:23
    render every single frame is affected by
  • 00:19:26
    this warp so if the quality of the warp
  • 00:19:28
    is bad bad this will make the entire
  • 00:19:30
    game look bad all of the time a little
  • 00:19:32
    different to what you see from frame gen
  • 00:19:34
    where that only affects a every second
  • 00:19:36
    frame or now three out of four frames I
  • 00:19:38
    guess reflex 2 is first coming to the
  • 00:19:40
    finals and valerant soon with support
  • 00:19:42
    for RTX 50 Series gpus initially and
  • 00:19:45
    other RTX gpus later so it doesn't sound
  • 00:19:48
    like this will be something restricted
  • 00:19:49
    to new Blackwell models however it's
  • 00:19:51
    important to note here that frame warp
  • 00:19:53
    in reflex 2 will not solve latency
  • 00:19:55
    issues with dlss frame generation
  • 00:19:57
    especially multiframe gener because
  • 00:19:59
    right now there is no indication it will
  • 00:20:01
    be integrated into games that support
  • 00:20:03
    dss4 multi or single frame generation it
  • 00:20:06
    might not even work together for all I
  • 00:20:07
    know Blackwell also supports RTX neural
  • 00:20:10
    shaders and RTX neural faces though I'm
  • 00:20:13
    not sure how soon we'll actually be
  • 00:20:14
    seeing those in games so it seems more
  • 00:20:16
    of a future looking thing for now Nvidia
  • 00:20:19
    claims that RTX neural shaders can be
  • 00:20:20
    used to compress textures by up to 7
  • 00:20:22
    times saving memory which is perhaps why
  • 00:20:25
    they're still being a bit stingy with
  • 00:20:26
    vram this generation but of course this
  • 00:20:28
    feature is absolutely useless in games
  • 00:20:30
    that don't use it making this not an
  • 00:20:32
    actual excuse for low vrm amounts on the
  • 00:20:35
    RTX 570 in particular so that is pretty
  • 00:20:38
    much everything Nvidia has announced at
  • 00:20:40
    CES 2025 the new lineup of GeForce RTX
  • 00:20:43
    50 Series graphics cards looks
  • 00:20:45
    reasonable at first glance but certainly
  • 00:20:47
    not to the level that blew me away
  • 00:20:49
    performance gains look reasonable when
  • 00:20:50
    you remove all the BS marketing stuff
  • 00:20:52
    and you features the value increase
  • 00:20:54
    looks modest to okay and the hardware
  • 00:20:56
    itself looks impressive the exception to
  • 00:20:59
    this would be the RTX 5070 which has
  • 00:21:01
    just 12 GB of vram at $550 us too low
  • 00:21:04
    for that class of graphics card in 2025
  • 00:21:07
    even though Nvidia are claiming reduced
  • 00:21:09
    memory usage through some of these new
  • 00:21:11
    features there are some games now where
  • 00:21:14
    12 GB is insufficient even without dlss
  • 00:21:17
    applied and most of the vram savings
  • 00:21:19
    come through dlss for model updates if
  • 00:21:22
    the base game still doesn't work with 12
  • 00:21:24
    GB of vram it doesn't matter if frame
  • 00:21:27
    generation is a little more memory
  • 00:21:29
    efficient this card really needed 16 gig
  • 00:21:31
    what's good to see is that pricing isn't
  • 00:21:33
    completely ridiculous or outrageous this
  • 00:21:35
    doesn't appear to be a repeat of the RTX
  • 00:21:37
    40 series where Gamers were treated to
  • 00:21:39
    little to no increase in value and
  • 00:21:41
    shockingly high prices for some models
  • 00:21:43
    it was a pleasant surprise to see that
  • 00:21:45
    in the same tier at least the RTX 570 TI
  • 00:21:48
    is now $50 cheaper and the RTX 570
  • 00:21:51
    matches the updated price of the 4070
  • 00:21:54
    after the 4070 super was launched of
  • 00:21:57
    course we still need to see how
  • 00:21:58
    performance games from those models to
  • 00:22:00
    get the required value increase but
  • 00:22:02
    Nvidia hasn't just jacked up the prices
  • 00:22:04
    like a lot of people are expecting I was
  • 00:22:06
    also impressed with dss4 claims but more
  • 00:22:09
    so with the model updates to improve the
  • 00:22:11
    quality of upscaling at least in theory
  • 00:22:13
    I haven't tested it yet the ability to
  • 00:22:16
    upgrade the dlss model in existing games
  • 00:22:18
    through an Nvidia app Feature is also
  • 00:22:20
    quite neat given many gamers were
  • 00:22:22
    performing manual DL swaps as for
  • 00:22:24
    multiframe Generation not solding that
  • 00:22:27
    feature yet given the implication for
  • 00:22:28
    image quality and latency especially if
  • 00:22:31
    it's used as a crutch to allow for
  • 00:22:33
    Native rendering at an even lower frame
  • 00:22:35
    rate previously I found with frame
  • 00:22:36
    generation at least for single frame
  • 00:22:38
    generation that you really need a
  • 00:22:40
    certain type of game for frame
  • 00:22:42
    generation to work well Works a little
  • 00:22:44
    better in third person games a little
  • 00:22:46
    worse in firstperson games so is that
  • 00:22:48
    still going to be the case with
  • 00:22:49
    multiframe generation is it going to
  • 00:22:50
    make it even worse for firstperson games
  • 00:22:53
    a lot of question marks there not
  • 00:22:54
    totally sold on it really have to test
  • 00:22:56
    that one personally and I absolutely
  • 00:22:59
    hate that we're now in a situation where
  • 00:23:01
    Nvidia can just claim ridiculous
  • 00:23:03
    performance games by generating more and
  • 00:23:05
    more frames maybe the next Generation
  • 00:23:07
    they'll be generating 100 frames so will
  • 00:23:09
    now be whatever it will be 20 times
  • 00:23:11
    faster or something which will be just
  • 00:23:12
    just silly so anyway that's it lot of
  • 00:23:15
    stuff that Nvidia announced here at CES
  • 00:23:18
    2025 feels like I've been standing here
  • 00:23:20
    forever talking about GeForce features
  • 00:23:22
    but yeah lots of exciting stuff to be
  • 00:23:24
    testing the performance the features and
  • 00:23:26
    it's not coming too far from now so
  • 00:23:28
    Steve had better get busy updating his
  • 00:23:29
    benchmarks to test all these new gpus uh
  • 00:23:32
    if you want to support our testing here
  • 00:23:34
    at Hardware unboxed and support the
  • 00:23:36
    channel we've got our patreon page links
  • 00:23:38
    to that is in the description below if
  • 00:23:39
    you sign up you get access to our
  • 00:23:40
    Discord chat which like with the am
  • 00:23:42
    announcement earlier today lots of
  • 00:23:43
    discussion about the announcement of the
  • 00:23:45
    GeForce 50 Series in there while it was
  • 00:23:47
    going on was checking in there seemed
  • 00:23:49
    like a bit of fun was happening so yeah
  • 00:23:51
    anyway that's it for this one thanks to
  • 00:23:52
