Polaris and Vega were ROP-limited, and performed worse than nvidia cards with similar tflop measurements.
The Xbox has a higher tflops rating because of more compute units, but it has the same number of raster units. Because the PS5 clocks higher, its ROP throughput will be greater. In a rendering workload like games this will make a difference. Whether or not this offsets the fewer compute units remains to be seen, but I’d wager the consoles are going to come out pretty much on par. There’s not going to be a big discrepancy like PS4 and Xbone.
