PlayStation 5 Pro to Introduce New First-Party Super Resolution Tech, 4x Ray Tracing Performance Uplift Over PS5

Sony is giving final touches to a first-party super-resolution technology called PSSR (PlayStation Spectral Super Resolution), according to a sensational new leak by Moore's Law is Dead. The company plans to debut the tech with the new PlayStation 5 Pro console, this November. The tech is unlikely to make it to the current PlayStation 5 console due to the underlying graphics architecture. PSSR, from the looks of it, is closer in function to NVIDIA DLSS than it is to AMD FSR. The tech leverages the over 300 TOPS of AI inferencing power of the RDNA 3 GPU powering the PS5 Pro, to drive an AI-based reconstruction algorithm. The RDNA 2-based GPU of the current PS5 lacks AI accelerators. The biggest driving force behind the PSSR development isn't just this AI-based upscaling tech, but the impact of upscaling tech on frame-times and whole-system latencies. PSSR apparently makes the PS5 Pro capable of being not just a 4K-class game console, but also one that's ready to take on 8K. Sony is, after all, a television company, and would want to create use-cases for its latest 8K televisions.

A lot is also being speculated about the GPU driving the PlayStation 5 Pro. We've known from several older leaks that it is based on AMD's latest RDNA 3 graphics architecture, but we're now learning that the GPU will be a mix-match of several current and future graphics architectures from AMD's IP bouquet. It could have more advanced media and display engines than the current Radeon RX 7000 GPUs, but even the shader engines could incorporate certain elements from a future architecture, such as RDNA 4. The report speaks of a total AI inferencing performance of 300 TOPS, an FP16 throughput 67 TFLOPs, and an FP32 throughput of 33.5 TFLOPs. To put these into perspective, the GPU driving the Xbox Series X is rated for 12 TFLOPs FP32.

I wonder how upscaling to 8k is going to look?

Here comes all the comments from people who hate Moore's Law is Dead because his leaks are not 100% correct 100% of the time or because they think he's "smug" (not sure how his "smugness" is relevant to the information in any respective leak and I thought the very inherent nature of "leaks" is that most of them will miss the mark, but those are the what I'm constantly told when I inquire as to the reason for their animus....personally, I have no feelings either way, but I'm always curious when people feel very strongly toward something that's seemingly insignificant)

If It's mostly RDNA3 based, then 33.5TFlops is basically a downclocked 7800XT to 2.18GHz.

My bet: The 4x increase in RT performance is likely attributable, at least in part, to upscaling utilizing specialized hardware. According to the specs, it says 300 TOPs from dedicated hardware, it should be similar to tensor cores.

You can't trust this source too much either... :p

RDNA3 has some improvements regarding dual issue of vector operations but in practice it is not generating much increased throughput. Maybe AMD can fix the compiler but it is possible there isn't enough bandwidth to make use of this.
That said, if the previous consoles are any indication, Sony has managed to make much better use of the hardware than Microsoft.

This does look like it is mostly a 7800XT with some extra sauce but at 263W, I don't think they can do it without a bigger chip or a process shrink. Maybe this one is monolithic instead of chiplet based, so that everything is on N5.

PSSR is huge. Even if the rest of the rumour turns out to be false, that alone is exciting.

Is he even correct 50% of the time? I just feel he shouldn't be used as a source for news articles.

Even a broken clock is right twice a day.

The claimed 45% performance bump is reasonable, AMD has made a lot of improvements to Zen/RDNA architecture over the past 4-5 years. Personally I have zero interest in a mid-gen console when PS6 is probaby due late 2027 (provided the typical 7 year console cycle remains). I'll stick with my PC anyway, but always nice to see new hardware coming out.

Yea even base PS5 can do 8K, of course only 1 or 2 games render at that and they are very low graphical games. Who cares anyway, most games render at around 1440p and are upscale these days and it'll remain that way a long time. Framerate matters more at that point.

Yeap, There should be a really nice flag with an extra large font, saying "Rumor" :P

I was going to make a joke about being able to remaster your remaster on the PS5 but I see it only works on first party titles. I dont know if first party titles have any remasters on the PS5.

Did you mean 3rd party? If yes, I dunno. Were GTA V or Skyrim remastered once more for the current gen?

He is way higher than 50% of the time and if data comes out later where it was wrong or needed to be updated, he does so in a later episode. He is one of the more reliable leakers.

I think it's just slightly slower than a 7700xt

That said, I would wait for the actual device.

TLOU was the first game that came to mind since ive heard so much about it but im not from the console fandom and dont know what is or what isnt a first party title.... or maybe I read the TPU title wrong and its not about first party game titles but the tech itself being a first party.

My remastering joke still works though. Just not very funny. But hey dawg, I heard you like remasters. So lets remaster your remaster.

(Really dont care enough about console gaming to know what is or isnt a first party title.)

Excited for this machine and it has nothing to do with the extra horsepower and everything to do with the abandonment of FshiteR which has been over used this console generation and is always crap... Hope at least that part of the rumor is true.

PS5 had no RT at all, barely some software crap, so 'course they'll say "we got x4 uplift in RT performance"

lol, Sony selling dreams since 2006

Well, I think there was some recent news about AMD developing an AI upscaler. If Sony is being moved by the AMD's efforts or the other way around, either side benefits.

Sounds like the Playstation varient is developed by Sony going by the patent they filed but I hope AMDs discreet cards benefit from it as well.

According to this leak (with no apparent red flags :p), there is dedicated hardware boasting 300 Tops of performance, roughly equivalent to the capabilities of the tensor cores found in the 3090.
So it wouldn't be suitable for other AMD GPUs. Using AI or not, it's just upscaling, nothing to get excited about.

If you played Final Fantasy 16 and other similar games on PS5 (I still console game frequently regardless of owning a 4090) you'd be excited. Image quality is god awful in console games that use FSR 1/2 even worse than on PC which is already pretty bad.
