AMD featured Navi 32 and 33 graphics cards Some specs have leaked, but as is always the case with the rumor mill, take these assurances with a full pile of salt.
Navi 31 is their flagship GPU RX 7900 XT and 7900 XTX They’ll be built around — the first of the RDNA 3 graphics cards to hit shelves next month — and the Navi 32 and 33 will be the GPUs below, though we don’t know which models they’ll be running yet (or when they might be unleashed).
What we know now, according to leaker @Kepler_L2 on Twitter as tom devices (Opens in a new tab) Reports, are the assumed base counts for these GPUs as revealed via AMD’s ROCm software (on Github).
Based on these results, Navi 32 will have 60 Compute Units (CUs) which means 3840 Stream Processors (cores), while Navi 33 will have 32 Control Units (CUs) or 2048 Stream Processors (this is the maximum configuration – there will be Also variants with cut amounts of cores, as ever).
It helps to put that in perspective, of course, and we can do that by comparing it to full-fat RNA 3 Main GPU, with Navi 31 providing 96 CUs or 6144 stream processors.
Analysis: Let’s be careful here
At this point, it’s tempting just to compare those core numbers and start to work out roughly how AMD’s relatively powerful second- and third-tier GPUs compare to the range-topping Navi 31. Some quick math indicates that the Navi 32 will only have less than two-thirds the number of cores as the main GPU, but there’s a lot more relative performance than that pure core count.
It all depends on what other specs AMD is running with Navi 32 (and 33), such as clock speeds (both core and boost), and also considerations like memory speed and bandwidth. All of these factors tie together into a complex equation when it comes to the kind of relative frame rates you can expect from the various RDNA 3 models.
All of this means we certainly can’t jump to any conclusions yet as to how this will reflect on Navi 32 and 33’s performance levels, and besides, we don’t even know how powerful Navi 31 is anyway. (All we have to go on are AMD’s chosen launch benchmarks which, of course, will show them in the best light – all hardware makers do, of course.)
Overall, there’s a tinge of disappointment regarding the online reaction to this leak, but we really need to wait and see how these GPUs might shape up – or at least until we get more spills and rumors that support not only the alleged core matter, But also provide more details about other specifications. Of course, pricing will also be a key factor, as always.
