Agree with Simon, very helpful analysis! I found your interpretation of the B580 limiting its efforts for Path Tracing in very challenging cases like Cyberpunk to make a lot of sense. Even a 4090 is taxed significantly by CP2077 with everything turned up to the highest settings, and you explained well how Path Tracing costs a lot of bandwidth and compute that is then missing elsewhere. Boils down to the graphics (drivers) team choosing wisely which battles to fight. 11 FPS just don't look good 😄.
Would be interesting to know how, for example, Nvidia's drivers deal with those choices across GPUs with very different capabilities. And, if someone from Nvidia reads this: Send Chester a 5090, so he can treat us to a great deep dive on Blackwell !
And, AMD, how about doing likewise with the 9070XT? RDNA4 sounds mighty good, maybe even better after a deep dive into it by Chester!

I have a 9070 on-hand and I'm working through rdna 4 stuff. There's a lot to do, give me some time :P
Great and helpful analysis, as always. Thank you!
(I might be wrong, but I think that any-hit shaders are used for shadows, not for transparency. With transparency, order matters)
Great article as always. Man, if only there were a big battlemage chip
