This is a bad port, no disagreements there.
But those 35 tflops figures Nvidia put out are fake. There are more knowledgable PC posters who can explain why that 35 tflops GPU is gimped and is effectively a 20 tflops GPU, but the gist of it is that nvidia is fudging the numbers because the performance does not match the tflops gains from the 2080.
Notice how its pretty much equivalent to a 20 tflops 6800xt despite boasting 35 tflops of power.
This also matches user benchmarks which put it just 60% faster than the 2080.
Now lets take a look at the 6600xt which is AMD's 10.7 tflops card. only 4% slower than the 2080 which on my system ran at 1950 Mhz consistently giving us 11.4 tflops. Math adds up here. However, look at how powerful it is compared to the 20 tflops 6800xt and the 35 tflops 3080. Same thing we saw above.
This basically gives us a 1.75x figure if we assume the PS5 is somewhere around a 9.9 tflops 2070 Super or a 1.64x if we go by the 11.4 tflops 2080. Either way, it is no where near the 3-4x claim the numbers have you believe. Of course, ray tracing changes all of this and looking at how Nvidia's 30 series cards are roughly 50-70% better at ray tracing performance, i would assume traditional ray tracing would put it around 2.5x. However, the matrix didnt seem to give my 2080 or 3080 a big edge over AMD cards so it might differ by implementation.
