If 7900 xt has 54 tflops and 350w I don't see the point to go nvidia. Dlss will be useless.
It's sounding like 7900 XT will have a lot more than 54 TF and consume much more than 350 watts. Going by leaks and rumors anyway.
I'm personally guessing it'll be around 75 TF and between 425 watts - 450 watts power consumption. No solid idea on shader cores tho; rumors/leaks have bounced between 12,288 and 15,360 a few times.
As long as there are IPC improvements console mid gen updates might just opt to not draw as many watts and have lower frequencies. If the rumors for 4090 are true it might go past the 100 TFlop threshold while PS5 is sitting at 10 TFlops. That's quite a generational leap, a PS5 pro probably doesn't have to go past 20/25 Tflops.
Just keep in mind TF aren't everything when it comes to gaming performance, not even close. Even if/when mesh shading becomes more prominent in the graphics pipeline (that's one thing where TF can matter because it is compute-driven and TF measure compute capability), you'll still need fixed-function processes, still need ROPs & TMUs, still need your primitive units etc. because different things may benefit from different functions.
It'd be funny (to me, anyway) if the 4090 is 100 TF but only has say 450 Gpixel/s pixel fillrate. I mean the 3090 is already over 3x the TF of PS5 but barely does 40 Gpixels/s more in pixel fillrate.
Nvidia tflops is half amd tflops nowadays. So comparing 4090 ti perf directly to ps5 would be 50tf vs 10tf
7900 xt will be 46-54 tflops probably at 400w
7800 xt 36-42 tflops probably at 300w
Even if u consider possible pro models on rdna4 these gen will not gonna catch these cards.
There's no way the 7900 XT comes in that low at performance unless set the clock to like 1.8 GHz or can only go as high as 2.2 GHz, and that's with a 12,288 shader core model. RDNA2 can already go much higher in clock, even the 6900 XT can boost to 2.5 GHz.
And again, it's not just about TFs. The consoles can make GPU, CPU, and I/O customizations the PC GPUs cannot, which can help even the score in some cases. And unless a game is massively reliant on compute-side processing, TF isn't going to matter that much.
