Some specifications of AMD's incoming Navi 32 and 33 graphics cards have been leaked, but as always with rumours, take these claims with a lot of salt.
Navi 31 is the flagship GPU that the RX 7900 XT and 7900 XTX will be built around (the first RDNA 3 graphics cards will hit stores next month) and Navi 32 and 33 will be the two underlying GPUs, though we don't know. . We don't yet know which models they will drive (or when they might be released).
What we do know now, according to leaker @Kepler_L2 on Twitter as reported by Tom's Hardware(opens in a new tab), is the alleged core count of these GPUs discovered via AMD's ROCm software (on Github).
Based on these results, Navi 32 will have 60 Compute Units (CUs) or 3840 Stream Processors (cores), while Navi 33 will have 32 CUs or 2048 Stream Processors (this is the maximum configuration; there will also be variants with slice - reduced amounts of hearts , as usual).
It's useful to put that in perspective, of course, and we can do that by comparing it to the full flagship RDNA 3 GPU, with Navi 31 offering 96 CUs or 6144 stream processors.
Analysis: Let's be careful here(*3*)
At this point, it's tempting to compare those basic numbers and start figuring out roughly how well the relatively powerful second- and third-tier AMD GPUs will stack up against the higher-end Navi 31. And some quick math indicates that the Navi 32 will have just under two-thirds the core count as a flagship GPU, but there's a lot more to relative performance than that pure core count.
It all depends on what other specs AMD uses for the Navi 32 (and 33), such as clock speeds (base and boost), as well as considerations like memory speed and bandwidth. All of these factors are tied to a complex equation when it comes to the kind of relative frame rates you can expect from different RDNA 3 models.
All that to say that we certainly can't draw any conclusions yet on how this might reflect on the performance levels of Navi 32 and 33, and besides, we don't even know yet how powerful Navi 31 is. of all forms. (Todo lo que tenemos que hacer son los puntos de reference de lanzamiento cuidadosamente seleccionados por AMD que, naturally, lo mostrarán de la finest manera; todos los manufacturers de hardware lo hacen, por supuesto).
Generally speaking, there's a tinge of disappointment in terms of the online reaction to this leak, but we really have to wait and see how these GPUs evolve, or at least until we get more spills and rumors supporting more than just the so-called kernel. . account, but also provides additional details on other specifications. Naturally, the location of the prize will also be a key factor, as always.
