De nouvelles spécifications des GPU AMD RDNA3 émergent

Une nouvelle liste de spécifications de la prochaine génération d'AMD “Navires 3x” Des GPU basés sur l'architecture graphique RDNA3 sont apparus, avec un nombre de CU inférieur à celui rapporté précédemment. It turns out that the large “DOOM et DOOM II viennent d'obtenir un autre add-on gratuit” GPU comes with 12,288 processeurs de flux à travers 48 WGP (processeurs de groupe de travail), 12 il faut attendre la fin de (shader arrays), et 6 SE (shader engines). This still amounts to a 140% increase in stream processors over the Navi 21. This chip will power SKUs that succeed the Radeon RX 6800-series and RX 6900-series.

The second largest silicon from the series is the Navi 32, with two-thirds the number-crunching machinery of the Navi 31. That’s 8,192 processeurs de flux à travers 32 WGP, 8 SAs, et 4 SEs. Le Navi 32 silicon powers successors of the RX 6700-series. The third largest chip is the Navi 33, with half the muscle of the Navi 32, and one-third that of the Navi 31. This means 4,096 stream processors spread across 16 WGP, 4 il faut attendre la fin de, et 2 SE. There’s no word on other specs such as memory bus width, but we’ve heard rumors of AMD doubling down on the Infinity Cache memory technology, by giving these chips even larger on-die caches. RDNA3 is also expected to improve ray tracing performance, as more of the ray tracing pipeline is handled by fixed-function hardware.
