7800XT is RDNA3 lol
PS5 Pro will basically have the performance of RDNA 2 16-17 TFLOPS.
i am talking about PR, not that it is a difference between architectures
Blame AMD for that.
Still 16.5TF Rdna 3/4 vs 10.2TF Rdna 2 is a huge upgrade.
no argument here. plus, Ethomaz showed the graph with AMD PR bullshit.Blame AMD for that.

No we're getting somewhere, you're spinning your tires not understanding this.
Just to people understand the Dual Issue.
It means you can issue TWO instuctions at the same time to a SP when you meet some rules (sending the same instruction to all SPs in a cluster).
That doesn't mean it will execute both instructions at same time.
It will still execute one instruction after the other.
The gain lies in saving the overhead to make two separably calls.
The gain is minimal to be fair.
And due that AMD used the marketing bullshit to say they GPU are now can do double the TFs they actually do.
And they don't.
A 30TFs RDNA3 will perform similar to 15TFs RDNA/RDNA2.

If those 33 TF were 3x over PS5 it would be more powerful in practical terms over a 4090 which due to thermals alone it would be impossible, let alone costs.
Sadly diminishing returns have been a thing for a long time. The PS5 pro will have high resolution gaming at 60 FPS to be more of a thing specially in those performance modes that used to hit 720p in some games.

I personally think the most exciting part of the specs is PSSR, AI and machine learning.
Still, 15TF RDNA 3/4 is not the same as 15TF RDNA 1/2.
It’s like saying a 3.5ghz Ryzen 1600 performs the same as a 3.5ghz Ryzen 5600.
Simply because the clock speeds are the same.
I don't give a fuck what DF said. All we're saying is
67 is in FP16
33.5 in Dual Issue
and 16.7 in FP32
If the PS5 Pro was really 33.5 tflops then why is it only 45% faster in rendering than the PS5 (10.3 TF)?
RDNA3 architecture is like that.

Exactly in terms of real performance per TFs:
RDNA > RDNA 2 > RDNA 3.
RDNA have a 5% better performance at same TFLOPS than RDNA2 but RDNA2 can reach way higher clocks so it can reach way higher TFLOPS... something RDNA can't.
RDNA3 is a bit slower than RDNA2 but it can do Dual Issue for marketing purpose.
BTW that was why RDNA3 was a big disappointment.
One because Sony is being modest.
Two I read somewhere 45-60 something.
Three because the GPU is being bottlenecked by the CPU and Ram.
Finally I never claimed we would get 3 times the power what I claimed was the GPU spec(that is somewhat hindered by the above)
IMO many unknowns exist with what's possible with it.
