Important news has arrived about AMD’s new generation RDNA 4 graphics cards. AMD RDNA 4 graphics cards will bring major innovations in ray tracing and will also be used in Sony’s PS5 Pro game console. Here are the details…
AMD RDNA 4 graphics cards will improve PS5 Pro ray tracing feature
According to the post made by user @Kepler_L2 on Twitter, AMD’s RDNA 4 graphics cards will offer major improvements in ray tracing technology. Moreover, most, or even all, of these features will also be available on the PS5 Pro console. Here are the features that will increase ray tracing performance…
New ray tracing features include: Double RT Intersect Engine The double-layer ray intersection engine, called Ray Tracing Engine, will make ray tracing operations faster and more efficient. RT Instance Node Transformation Ray tracing sample node transformations will make graphics more dynamic and detailed.
64B RT Nodesthat is, 64-byte RT nodes will make it possible to perform ray tracing operations more precisely and accurately. Ray Tracing Tri Pair Optimizationwill increase graphics performance by increasing ray tracing optimization of triangle pairs.
Bounding Volume Hierarchy (BVH) Improvementswill offer improvements that will speed up ray tracing by representing geometric objects with simpler structures. Moreover, OBB and Instance Node Intersection support will support ray tracing even in more complex scenes.
As for the PS5 Pro features, the eight-core Zen2 processor comes with a 3.85GHz high frequency mode, in this mode the GPU performance drops by approximately 1%. The GPU’s rendering speed has been increased by 45% and ray tracing performance has been tripled. Memory bandwidth increased by 28% to 576GB/s, and available memory for games increased by 1.2GB. Additionally, PSSR super resolution technology and 300T 8-bit AI computing power are supported.
In other news about AMD’s RDNA 4 series, it is stated that these cards will be produced with TSMC’s N4P process and the chip density will be increased. Most RDNA 4 graphics cards will use 18Gbps GDDR6 memory, which may be lower than some RDNA 3 models. But performance will still be impressive. The flagship model of AMD’s RDNA 4 GPUs will feature 50% more shader engines than the Navi 31.
