| BraLoD said: How come AMD can't use machine learning on their GPUs until they scale up their hardware, but Sony using an AMD APU can use machine learning and get way better results on AMD hardware than AMD with FSR? Clearly the hardware is capable of it if Sony is pulling it of. |
Sony's is a closed ecosystem.
AMD doesn't have dedicated Machine Learning cores like nVidia's Tensor cores across it's entire hardware stack.
...Yet.
That doesn't mean AMD's fastest GPU the Radeon RX 7900 XTX can't do Machine Learning, it absolutely can... But, it needs to run on the shader pipelines which takes resources away from the GPU that could be used to render the game.
In short, there just isn't any point to it yet.
And AMD's hardware that benefits the most from A.I Machine Learning upscaling? They suffer from the same issue as the above Desktop GPU's like the Ryzen Z1 Extreme in devices like the Rog Ally.
However... AMD does have the Strix Point APU's which could do it in hardware. - But what's the point in releasing a DLSS alternative when you only have a couple of APU's that can leverage it?
Things will change when AMD moves away from RDNA3 across it's entire product portfolio.
| HoloDust said: I think PS5 Pro has tech from next iteration of AMD's GPUs, with hardware that PSSR is running on, that base PS5 does not have. AMD's GPU series (8000) will have that hardware, so I'm guessing something similar to PSSR will be their counterpart to DLSS. |
Correct, AMD backported some design elements of RDNA3.5 and scaled them up for the PS5 Pro.
| BraLoD said: Maybe it also has some separated processors they developed themselves to do the machine learning part and it has nothing to do with AMD. |
AMD had already done the work with Strix point.
| CosmicSex said: Actually if we are being honest: DLSS is not superior in every aspect. In fact the only area where DLSS is clearly superior is in processing certain forward motion vectors. DLSS is also 4 years old and PSSR is on its first iteration. |
If we want to be truly honest... DLSS>XeSS XMX>PSSR>XeSS Dp4a>FSR in terms of quality.
DLSS is superior.
PSSR vs DLSS differences.
* PSSR has fizzle, DLSS is much more stable.
* DLSS has better temporal stability with geometry. - Less edge shimmering/flicker.
* PSSR has a more Aliased output.
* DLSS provides a sharper, cleaner image over PSSR. - Regardless if it's a still or moving frame.
* PSSR smears/ghosting in Ray Tracing.
PSSR does have a few advantages, like less aliased/checkered resolve on reflections... But overwhelmingly DLSS is far superior.
| CosmicSex said: PSSR, in its first iteration is more than good enough, completely leaping over FSR and matching DLSS in most areas. We expect it to improve over time. Results in games like FF7 and TLOU are quite transformative and it will be providing PlayStation gamers with a very decent alternative to FSR and DLSS.  Other games will do doing 8K60 upscaling which, according to the people who have actually seen it, is incredible. |
1) It's not matching DLSS. It's not even matching XeSS XMX. But it is beating FSR and XeSS Dp4a.
2) It's definitely "good enough" which is a statement I stated earlier.
3) Improvements is expected. - However DLSS will also continue to improve, which has been happening for years, that won't stop because the Playstation 5 Pro has a competing technology. - And just because the Algorithm has improved, doesn't mean all games will benefit from that.. Developers have a bad habit of not supporting games over time.
| CosmicSex said: As far as AMD cards go, this is the BEST iteration of an upscaling tech availible on any AMD hardware. |
Correct. Good thing on PC... You aren't limited to AMD, you have nVidia and Intel.
| CosmicSex said: Can they make it better and improve for the PS6, for sure, but there is no real reason to devalue the work they have done here. |
AMD will be taking some learnings from this which will benefit the next Xbox and Playstation as well as PC.
And nothing is being devalued, I am stating some hard truths.
AMD can't beat nVidia yet, they just need to be "good enough".
