Hardware Lumen is roughly 18% heavier than Software Lumen according to Alex's own findings in the matrix demo. himself. He's seeing a 50% increase in pixels. That gets us to 68% better performance.
That's not how the math works - %s are multipliers. If those translated directly to performance (as you alluded to) - that would give you 77% total increase.

and the rt cores are also 2x faster not just for the extra 24 CUs, but for all of 60 of them.

either way, its insane to suggest that the 50% increase in pixels is not in line with the specs.

huh? PS5 is 10.2 tflops. PS5 Pro is 16.7 tflops. 36 CU vs 60 CU. 66% more compute units. Same clocks. Thats a 63% boost in compute power. Not to mention the 2x better RT performance thanks to new RDNA4 rt cores.

We have no seen games perform upto spec, but that doesnt mean the performance here doesnt align with the spec differential when it literally fucking does. If anything the other games where the console is offering only a 30% boost are the ones where the performance doesnt align with the spec.

1.5 x 1.18 =1.77

You don’t add 50+18. Come on.

I'm tempted to suspect that the unpatched PS5 Pro Boost mode is just a PS5 overclocking mode.

Example) Zen2 3.85GHz + 36CUs 2.5GHz + Memory bandwidth +28% = 30-35% fps boost
* Disabled additional 24 CUs

SONY should release detailed specs for the PS5 Pro.

Wow nice update! 56% increase in resolution while support HW RT. Alex really knows how to showcase raytracing features and it shows. The game has a "darker" more grounded look than base PS5 now thanks to the better RT accuracy.
I would have liked to see performance comparison against a 6800 XT/7700 XT though, why not do it in this game if he knows the settings?

Locked 60fps and dynamic resolution fuck up chances for fair comparison.

Why patched games also (mostly) show ~30% gains?
