This demo favors the 6000 series. The RTX 6700xt is a 13 tflops card. only 9% more powerful than the XSX. And yet it is averaging 44 fps while the XSX and PS5 average around 25 fps around the city.
Those benchmarks were done with a 12900K. That CPU is a lot faster than Zen2, especially one with cut down clocks, cache and higher memory latency.
On a demo that is so heavy on the CPU, that 12900K is doing a lot to skew results.
More importantly, it is destroying the 2080 and 2080 Super which are usually much better at ray tracing performance and on par with it in standard rasterization so clearly the game was optimized for RDNA 2.0 GPUs found in consoles. And yet, the consoles are struggling to hit 30 fps at a mere 1080p although TSR might have some kind of performance hit compared to native 1080p results we see here.
AMD has already released a first set of drivers optimized for this release of UE5. Nvidia still hasn't done that.
Also consider that a lot of shader code is optimized for RDNA2, since this is the base for current gen consoles.
Still, things dont add up. The PS5 and XSX are underperforming. They are both roughly on par with the 2080 if not the 2080 Super, but they arent performing like they should here despite the same RDNA 2.0 family cards destroying even 30 series cards on PC.
It's a CPU bound tech demo. And the PS5 and Series S/X have a good CPU, but it's not high end stuff.
