Nah man, both comparisons are wrong. I would go with Second Form Frieza for base PS5 and Third Form Frieza for PS5 Pro. An incremental step towards the actual big transformation.

That as well, but there are double the execution units in RDNA3 and when you can dual issue (limited scenarios in RDNA3, slightly expanded on RDNA3.5 IIRC) you can get to double that peak… when you can dual issue you can get then another bump by using FP16 and even more with INT8/4.

The leaks were from dev documentation. So pretty much confirmed by Sony.
Dual Issue is part of RDNA3.x and PS5 Pro GPU has a lot of new architectural changes… new ROP, new RT units, WMMA instructions (AI acceleration), etc… why do you draw the line at VOPD instructions?

The Playstation roaches are the ones inflating those Teraflops from what I can see. Green rats are somewhat quiet, because Xbox is pretty much dead at this point.
What's to inflate?
The numbers are in the official leaked technical documentation for developers which was obviously right about everything?
It's 16.7tf and 33.4tf with dual issue with half precision.
It's also not relevant to talk about teraflops since the key features of the Pro are the PSSR and the new advanced ray tracing architecture. The rest is there just to support the new features.

The claim about dual issue theoretical peak is separated from FP16 usage. PS4 Pro, PS5, Xbox Series X|S, etc… and now PS5 Pro can use FP16 or lower precision to boost throughput.
Finding code that benefits from both dual issue and FP16 will be rare, but that would run at 4x the base FP32 rate for that section of the code.

This was a curious case on PS4 Pro, it used "geometry upscale rendering" that was advertised (or at least mentioned) before the release of the Pro, but saw little use. Basically, the geometry runs at native 2160p, while pixel shaders run at 1080p. The resulting image is a mixture of sharp and blurry, but in case of Gravity Rush, it worked well enough.
Edit: of course this has already been discussed, should read the thread to the end before replying, but ehh, I'll still leave this here.

It's absolutely mind-blowing people are complaining about the dual issue teraflop number that AMD itself uses for their graphics cards since RDNA 3....
Check the 7800 XT teraflop number....

Take the L. You made a mistake. It happens. No point moving the goalposts now.

I wonder if 8k is achievable through pssr when it's matured 
definitely not powerful for a complete 8k image but maybe a set resolution upscaled to 8k without sacrificing image quality. I'm more intrigued how capable pssr can be

I get zero info on Nintendo sadly
It doesn't really matter if the code is rare or not, because as always, <10% of the code is responsible for all the slowdown.
Good programmers will find, using profiling, the sections of code that need to be boosted, and such a feature will no doubt prove useful.
No. RDNA3 can dual issue some instructions/operations so the FP32 FLOPS is double.

Sure, might be also limited by bandwidth at some point, but it is not a waste of transistors if not Cerny would demand changes… see how they got AMD to redesign the Ryzen 2 FPU: https://chipsandcheese.com/p/the-nerfed-fpu-in-ps5s-zen-2-cores

There seem to be a lot of confusions, PS5 PRO is 33.4 TF with dual issue at full fp32 precision, not half precision. So the theoretical max of the machine is officially 33.4 TF. Dual issue feature exists, it is not to be dismissed wishfully. It can ad a significant ~15-20% of compute performance especially in a fixed spec APU.

Of course it was. The Touryst plays at 8K/60fps on base PS5.
Please make researches before saying shit like this. It's alright to be wrong, it happens to me all the time.

Oh this is so highly ironic. If you'd bother to watch the video - it renders internally at 8K, but that is supersampled to 4K, because, yes, the base PS5 lacks the HDMI bandwidth to actually output in 8K. But as you say, it's alright to be wrong.

Well said. Asked Expert in Germany and they told me that Sony isn't providing disc drives till early 2025.Guys, we are almost there and Europe is the land of no disc drives.

I'll let you know once I see how Black Myth Wukong runs on it and how it compares to a budget PC. That game should've been the showcase for PS5 Pro, but it's strange how it's not on the list of enhanced games, but hopefully added soon.

TLDR 32 Gbp caps 8k at 30fps with 4:2:2 chroma subsampling. Also forces you to pick between HDR or 4:4:4 chroma subsampling at 4K/120. I assume the Pro doesn't support DSC either. Kind of an own goal for a console that focuses on IQ as a selling point to not go with 40 Gbps. Never mind if it does support DSC.

The funny part is that MediaMarkt keeps saying that it “will be back in stock soon” on the product page…

I wish.
Ignoring the cost of the original PS5 we all paid four years ago, this thing is $500 more in Canada. I paid $720 after tax for the original. The Pro with stand and disc drive (both included with my PS5) is over $1200 after tax here.

PS5 Pro had an increase in strength when they improved the GPU, but the whole is held back by the weak CPU.
I think the analogy is perfect, because Ultra Super Saiyan is kind of an imperfect SSJ2, in the same way that the PS5 Pro is an imperfect PS6.

Show me the CPU constrained games... this makes zero sense.
PS5 will get cross gen games with PS6 and these games are gonna be obviously running on the same CPU...

Any game with RT, games that use Unreal Engine 5, recent Capcom games like Dragons Dogma 2, etc.
PS4 received multis from PS5, even though it has a tablet CPU. Your argument doesn't make much sense.

There's no 33.anything tflops, it's an RX 6800 with RDNA 4 RT and ML Bolted on, it's 16.7 teraflops.

Many aren't taking into account the fact that Sony is using FP32 to describe the performance of the Gpu in the pro, not FP16, which is what gpu vendors typically use when AI is involved in the pipeline (PSSR), which frees up gpu resources for other uses. It's why it's rated at 16.7 TFLOPS & not 33.4, not taking into account the design differences between the RDNA 3 compute unit and the RDNA 2 compute unit, which already makes the ps5 pro GPU much different than that in the base console. Perhaps Sony don't use FP16 in their metrics since the pro uses a hybrid rdna 3 and 4 gpu.
Nvidia has been using FP16 numbers to describe the performance of their GPUs since the Turing arch debuted (due to dslr becoming a factor in the pipeline). Amd doesn't do it yet, since they don't have bespoke ML hardware in their GPUs (that might change soon enough though).

Yes, it's an RDNA 2.0 RX 6800 with added RDNA 4.0 ML and RT cores added, that's where all the evidence points.

Presumably the 7800 XT is just the 6800 with VOPD and cache changes. And the 8800 XT will be the 6800 with VOPD and cache changes and extra RT and ML hardware. Or maybe we can go back to RDNA 1 and say the 6800 is just the 5700 XT with 50% more CUs, support for DirectX 12 and Infinity Cache. So that the RDNA 4 cards are really just souped up RDNA 1 parts.

I'll be testing Red Dead 2 v1.00 to see if there are any improvements.

Yeah, I think it make sense, if you could do FP16 for Graphics and FP16 for AI in one clock, if that it is possible, remains to be seen. That way you could achieve something which does not look that good into something which look nice at almost the speed, as there wouldn't be even any AI model running. It would probably also help with latency.
FP16 driven graphics is something which does looks kind of trashy, but if you would have model to mask those downsides, you would gain a shit-ton of performance. For a visualisation, a lot of mobile games operates at half precision, which means a lot of artifacts, but given the super high density screens, its not as noticeable. Or people just don't care.

That GPU isn't released yet.
PS5 Pro is RDNA3.5 + RDNA4 (with RT + ML) features. The latest AMD GPU is still RDNA3.

Maybe I made a mistake and should have had my PS5 ship instead of pickup. Eliminated any chance of getting it early in the latter method.

Really?
Not one single title outputted 8k. And only a single title rendered in 8K which is what you tried to move the goalposts to.

Can't believe in 2024 some people don't know the difference between rendering resolution and output resolution...

33.4 TF figure has nothing to do with fp16 though, it's fp32 with VOPD.

With some Rapid Packed Math thrown in there probably.

That would be 66.8 TF with RPM (fp16).

If Sony had put 33.4 tflops on the box the 45 percent faster rendering wouldn't make sense would it?

Pretty much. But, nowadays, floats aren't only used for raster alone, Rt is also part of that computation and since Amd has the RT core and the compute Unit together as one, their compute performance is measured differently. Nvidia has the compute and rt units on the same chip, but separate and thus their performance is calculated separately.
