You're right, PSSR will improve performance and image quality, because it means devs can use a lower resolution to increase frame rates but not give up IQ because of PSSR.

Yes, framerate or graphics but the problem is many games are already in low resolutions even for PSSR/DLSS to handle things for 4k screen. Just some quick comparisons without RT into play:
1. Game runs 1440p on PS5 in 60FPS, devs can leave that 1440p for Quality PSSR and have 45% more power left for better framerate or graphics quality (or both) OR they can drop to 1080p and have more than 100% performance increase in total. This is ideal scenario.
2. Game runs 1080p on PS5 in 60FPS, devs can realistically only switch from FSR to PSSR so they have 45% more performance left. This will be the most typical scenario based on resolutions we have right now.
3. Game runs 1080p on PS5 in 60FPS but struggles to keep that FPS, runs around 45-50FPS. Most of the performance uplift will go into fixing performance, we could see games that look essentialy identical when it comes to graphical features but have better performance and image quality (while having the same resolution)
4. Game runs in 900p or 720p in 60FPS on PS5, all that + power of the Pro will go into fixing image quality of the game, increasing resolution to something that PSSR can change into good 4K experience. No change in performance or graphics.
5. Game runs in 900p or 720p but struggles to reach 60FPS, I won't even comment on that and we have games like that on PS5
Even DLSS can't produce good IQ (in motion) from 720p to 4K so some games will look like shit anyway...

a 7700XT will be comparable to a 4070 in rasterization but way off on RT, but PS5 Pro will have better RT capabilities than a 7700XT.

This is just a baseline example, 45% more headroom is massive, in reality if a game runs at 720p and struggles to reach 60fps on PS5 then it's a pile of shit and wouldn't run well on a 4070 either, it's all relative right, some games are just not saveable no matter how much brute force you throw at them.

4070 is still above that by more than 10% and 3080 is almost 20% better in raster.
45% is big and also... not big. It will take 30fps game ~45FPS and game that runs in 45FPS (like wukong hahaha) to stable 60. This is nice improvement but nothing earth shattering.
When it comes to resolutions 45% won't even let you go from 1080p to 1440p...

Firstly that's relative performance assuming PC, DX11/12 PS5 vs 2080Ti has a 25% relative performance increase toward the 2080Ti, but I can play Fortnite at a very stable 120fps on PS5 but get around 70/80fps on a 2080Ti at the same native resolution, PS5/Pro have other advantages over PC's.
There are PS5 games that have offered similar performance to a 2080Ti at the same settings which defies expectation of the PS5, all engines are not created equally.
Secondly - you can't have it both ways 45% is huge or 10% is nothing - it will be comparable to a 4070 and will surpass it in some titles.
Wukong will do 120fps on PS5 Pro PSSR upscaled from 1080p with the same settings and better IQ thanks to the 45% uplift in rasterization and the improved 4xRT increase assuming they patch it.

In 2020 when PS5/XSX released both consoles were compared to 2070S - 2080, nothing changes since then other than Nvidia and developers not giving a fuck about turing architecture anymore. Raw power of PS5 is still around that level. 2080ti is comfortably above that and your anecdotal evidence is just that, anecdotal evidence. Go watch some DF videos.
Wukong runs in 45FPS in 1080p, you need that 45% just to reach stable 60 in 1080p. It also uses software lumen so 45% is all you get from raster improvement. If they patch it it will be more heavy anyway, hardware lumen performs worse than software version on Ada cards even with best RT hardware available.
120fps only with frame generation...

PS5 outperforming the 2080 Ti by 50%? I don't think so.
There is one game: The Last of Us Part I.
gooner4life_uk

I stated it will run 120fps if they patch it to include PSSR as an upscaler so running on the same settings, not if they improve settings.
I don't need to watch Digital Foundry videos, I have 2 rigs here with a 2080Ti and a 4090 as well as a PS5, I can run my own comparisons, PS5 performs to a 2080Ti level in some games because of the other benefits of the PS5 arch and API's vs a PC, of course nothing improved from a hardware level, nobody claimed that, this will be my last response to you, because you don't actually know anything, you're just parroting things Digital Foundry have said and quoting 45% from developer documentation like it's going to be a straight 45% uplift, like i said, it's a baseline, most games will offer more than 45% improvement overall on PS5 Pro vs PS5, some will offer less than 45% it depends on the engine and the developers.

Where did I say PS5 outperforms a 2080Ti by 50%, I used one example, being Fortnite where 2080Ti struggles at the same settings as PS5 and get's outperformed by 30/40% unless I drop to DX11 on the 2080Ti where it will perform within 5% of the PS5.

Welcome! Rumour from the same dude who leaked the PS5 Pro design is that we're getting an announcement in the first two weeks of September. We'll see though.

70-80fps to 120 is a 50% increase using 80fps as the baseline. This never happens.
"I don't need DF." You sure as shit do because your magic PS5 is performing almost like a 3090 and we're all dying to see it in action.

120fps vs 80fps is a 33.33% uplift in FPS, PS5 performs nothing like a 3090 and i haven't claimed it anywhere.

You forget that Fortnite uses dynamic resolution on PS5 so good luck comparing this title.

Yet here we are:
Stop comparing 7700xt to PS5 Pro in such a rudimentary manner. It has much better memory setup.
Gaiff
SBI’s Resident Gaslighter
This is not how basic mathematics work.
The baseline is 80fps. You add 50% to 80fps, what do you get? 120. 80 x 1.5 = 120. The PS5 performs 50% better than the 2080 Ti in this case or the 2080 Ti performs 33% worse than the PS5. Either way, that's 3090 territory and it's bollocks.
Thanks for replying to me your a legend I always look for your comments on this forum

No doubt about that: the memory setup is the same as the 7900 GRE
256 bit/16 GB/18 Gbps
13.7 GB are available for games so still more than 12 GB

It has faster memory for sure but you forget about super fast L3 memory that both 6800 and 7700XT have while PS5 Pro don't.
NMS update probably talks about upper bounds of dynamic resolutions, we will see actual stats in game.

I didn't forget anything. IC means jack shit at the output resolution levels PS5 Pro will be rendering.
No, lower bounds.

It talks about lower bounds of dynamic res
If infinity cache means jack shit for ~1080p then more memory bandwidth of PS5 Pro (vs. 7700XT) means that as well...
Game probably doesn't have to drop res as low thanks to that INCREASED MEMORY BANDWITH of PS5 Pro vs. PS5.
1080p - 2 073 600 pixels
1440p - 3 686 400 pixels
1440p needs 78% more power.

I wasn't aware of PS5 using TSR and dynamic resolution the IQ is very very good in that case on PS5, I haven't checked Fortnite on the 2080Ti for a while, but i'd expect it will easily hit 240fps in DX11 but i don't think it would get anywhere close to 200fps with DX12 and Nanite/lumen enabled even with TSR and Dynamic Res on the 2080Ti based on past performance.

Fornite on the consoles uses dynamic resolution with TSR with a 4K target and the range is 864p-1836p. The average according to epic is 55% of 4K or 1188p. DF's analysis said it's comparable to High settings on PC. That's in the 60fps mode. The 120fps mode also gets rid of software virtual shadow maps, Lumen and Nanite.
I can't find something similar for the 2080 Ti because it's too old, but here is a 4060 running it at 1080p/High/Nanite and Lumen off and no dynamic resolution. He gets 200fps+.
Shortly after, he also runs it at 1440p with the same settings and gets over 130fps.
No way does a 2080 Ti with 120fps mode PS5 settings and resolution gets a paltry 70-80fps..

Kinda have to. In the absence of an actual PS5 Pro, all we can do is use PC parts in a similar ballpark to get an idea.

People will keep jumping in and correcting people if they keep posting things about PC that are blatantly wrong.
As for those that will actually buy it, well I’m one of them. Just because I’m PC first doesn’t mean I don’t extensively play PS5 as well.

This is from the same article.
Now, lets talk about that 123TFLOP FP16 number that AMD claims. While this is technically correct, there are significant limitations on this number. Looking at the RDNA3 ISA documentation, there is only one VOPD instruction that can dual issue packed FP16 instructions along with another that can work with packed BF16 numbers.
These are the 2 VOPD instructions that can used packed math.
This means that the headline 123TF FP16 number will only be seen in very limited scenarios, mainly in AI and ML workloads although gaming has started to use FP16 more often.
In the article, it states Dual-Issue can work with FP16 & BF16 instructions.
Below we can see WMMA utilizing FP16, BF16, & Int8 instructions.
From my understanding, it seems the SIMD32 utilize the AI Accelerators for higher throughput when doing Matrix operations but the AI Accelerators aren't dedicated in the same way as CDNA2 Matrix Cores. Maybe this changes in RDNA4.
You can read more on RDNA4 here.
Examining AMD’s RDNA 4 Changes in LLVM
Yeah I already discussed that quite a few messages back and showed exactly how those two instructions expanded, and then in my next message in the thread I showed how that aligns to the GoW Ragnarok ML AI implementation.
As for the WMMA, I might be misunderstanding but I thought it was just a hardware scheduler that could see opportunities to improve throughput by identifying scaler ops being done in vector ops and eliminating redundant work like multiplying with zeros that is common in lots of matrix maths like ML regression training and transforms. But for inference that wouldn't be the case as all the vector components will be needed with very low frequency of multiplications with zeros AFAIK to inference a pixel prediction in a PSSR, so ignoring the WMMA scheduler and manually writing inferencing to use either of those two dual issue packed BF16 or FP16 instructions would still be far superior performance and precision IMO, and especially as the BF16 would yield quality of eight FP32 vector components in 4 multiplications and 4 accumulations per instruction.

Honestly the only reason I'm on here going back and forth with people is out of love and cognizant of the fact that in another week or so this thread will effectively die and I'm sad about it
Anyways, back to arguing...
Lol 1080p? Are you crazy my friend!? Try 4k output always. Even when upscaling with PSSR it will always be a 4k output aka 4k size framebuffer and memory requirements.

- (Raster) performance between 7700XT and 7800XT depending of games
- With much better RT
- PSSR similar to DLSS (not sure how, technology or performance or both)

Ok fine I will post some charts...
Using the base PS5 as the starting point, its easy to see what we should expect from the pro.
Lets take a game like Star wars for instance. Here is it running at max settings and at 1440p
Notice the 7700XT is at ~40fps? Thats about the minimum we should expect from the PS5pro. The difference being that in a game like this it may tweak its IQ presets a bit (so not high/ultra across the board) and may even drop the rez from 1440p to 1296p then add RT better than whatever is used in the base PS5 and use PSSR to get it to 4k. That would be the PS5pro fidelity mode. In a situation like this, depending on how the devs wanna push it, you can even get a 60fps fidelity mode in such a game.
Then now lets look at the same game in 1080p
Now notice the game is running at 64fps? Again, the PS5pro will have tweaked IQ settings, which would typically mean it can get closer to 75fps+ in this mode. But its likely that they would then go onto add RT in this mode and have the game average 60fps.
Fme... I don't bother with all that relative performance stuff, as there can be a lot of little differences between GPUs that we can't account for. I just look at game performance... I believe the PS5pro would be at the very least, as good as the 7700XT. So I use that as my baseline, look at how it performs at 1440p and 1080p... and extrapolate from there. Thats a $450 GPU. And mind you, the PS5pro has more RAM, more bandwidth, better RT and PSSR.
Using the base PS5 as the starting point, its easy to see what we should expect from the pro.
| PS5 | PS5Pro |
| 1440p-4K@30fps (Fidelity Mode) | 1440p + PSSR > 4K @40fps+/ ~1296p + PSSR >4K @ 60fps |
| 900-1080p@60fps (Performance Mode) | 1080p + PSSR > 4K @60fps+ (maybe as high as 80fps)/ 1080P + PSSR > 1440p + RT @ 60fps |
Truth be told is that most of this stuff is moot. I think a better way to look at this stuff... is something like this instead.4070 is still above that by more than 10% and 3080 is almost 20% better in raster.
45% is big and also... not big. It will take 30fps game ~45FPS and game that runs in 45FPS (like wukong hahaha) to stable 60. This is nice improvement but nothing earth shattering.
