PCGN - AMD co-developed Microsoft’s DXR 1.1 API to speed up Xbox Series X ray tracingMicrosoft and AMD, however, worked together on the latest iteration of the DXR API specifically to aid the Xbox and RDNA graphics cards. But DXR 1.1 is still entirely backwards compatible with Nvidia’s GPUs, which would suggest there will be some commonality across all platforms.
“Microsoft DXR 1.1 API… was co-architected and co-developed by AMD and MIcrosoft to take full advantage of the common ray tracing architecture,” says Wang.” This is a great proof point of the benefit of ‘Radeon everywhere’.”
Or at least it will be if there is a tangible performance boost for Radeon’s ray tracing versus GeForce RTX ray tracing for similarly priced graphics cards. If developers are coding specifically for AMD’s ray tracing methodology for consoles, and it is significantly different to Nvidia’s, then you would naturally expect performance to be better for the red team. But only time will tell how that all plays out.

XBox Series X / RDNA 2 - up to 380 miliard ray intersections/sec (380 GigaRays/sec)
RTX 2080 Ti / TU102 - up to 10 miliard ray intersections/sec (10 GigaRays/sec)
Oboje jsou hausnumera, ale dafuq?
Právě jsou to hausnumera, ale jinak je to stejné. Obě čísla jsou uvedena pro stejné operace za sekundu (ray intersections/sec), ale nevíme za jakých podmínek atd., takže stále hausnumera, ale když už to tvrdí Micro$oft...Timmah! píše:https://www.resetera.com/threads/xbox-s ... 51/page-28
tu sa to rozobera v diskusii podrobnejsie.
Niekto tam spocital, ze tych 380 miliard treba vydelit 10, cim sa dostavame na 38 Gigarays, cize 4x viac ako 2080Ti.
Nato mu ale zase iny clovek napisal, ze tych 380,resp 38 nie su Gigarays, ale len tie "intersections" a to su dve rozdielne veci. Naopak, MS vraj tvrdi, ze RT jadra same o sebe maju vykon 13 TF, zatialco Nvidia pri prezentacii Turingu prisudila RT jadram 2080(nie Ti) 23 TF...
Este inak:
"The RT cores in the XBOX are doing 13TF worth of RT work. So 13TF RT + 12TF Raster = 25TF.
NVIDIA claims 35TF for the 2080, spread out like this: 23TF RT + 10TF Raster + 2TF INT/FP execution = 35TF.
So according to that metric the 2080 is 40% faster in RT than the Xbox Series X. The 2080Ti would be at least 85% faster."
Takze suma sumarum, vie boh ako to je
Ale predpokladam, ze nejako zasadne rychlejsie ako u Turingu to nebude, a ak nahodou ano, tak Ampere to minimalne dorovna, resp. dalej navysi.
