AMD’s flagship RDNA 3 GPU may not have an all-new design after all - SociallyKeeda

AMD’s subsequent-gen flagship graphics card (Navi 31, presumably the RX 7900 XT) may not go for a multi-chip module (MCM) design sporting two separate GPUs as beforehand rumored, and will stick to a single GPU (as historically used) as an alternative.

Before we go into this, we must always make it clear that the twin GPU rumor is simply that – hypothesis that Team Red will construct the flagship round a pair of GCDs (graphics compute dies) – as is the chance that AMD would possibly stick with the prevailing monolithic design it has at all times used for its Radeon shopper graphics playing cards.(*3*)

With that firmly in thoughts, a number of sources, together with 3DCenter and RedGamingTech (as PC Gamer noticed, the YouTuber underlines that a number of outstanding Twitter leakers have joined in with this hypothesis), are actually arguing it is perhaps the case that Navi 31 will run with simply the one GCD.

The idea is that AMD might use a configuration of 1 primary GCD (5nm), hooked as much as six reminiscence chiplets (MCDs, constructed on 6nm), which might be a seven chiplet design.

RedGamingTech believes that we are going to see Navi 31 sporting 12,288 cores, and that it’ll run with 24GB of VRAM, greater than the 16GB quantity beforehand rumored (with a 384-bit reminiscence interface).

Analysis: Two turns into one? Maybe, or possibly not…

As PC Gamer suggests, it may be the case that AMD has not been in a position to notice the dream of getting two GPU chips working collectively seamlessly, in order that they’re solely seen as a single GPU by the system – avoiding the issues and issues that have traditionally plagued the likes of SLI and CrossFire options whereby two graphics playing cards are linked collectively. (In these circumstances, you don’t get twice the performance – the uptick may be a lot lower than that, and different points can crop up too).

In brief, it’s a thorny conundrum to deal with, and RedGamingTech asserts that they’re ‘pretty confident’ AMD has deserted the 2 GCD configuration (which was additionally rumored to be for Navi 32, by the way), and can now run with a single GCD. RedGamingTech does make it clear that they’re not sure, although, and cautions in opposition to being too certain on this level. And certainly another leakers disagree that AMD is swerving away from the 2 GCD design for Navi 31.

Coreteks argues that AMD is sticking to the beforehand rumored plan, asserting that the variety of patents the corporate has relating to a brand new design with a number of GPU chips suggests that is the route Team Red intends to take. And additionally that having a single GPU with the theorized six reminiscence chiplets doesn’t make sense from a latency standpoint (an necessary consideration for gaming performance).

What all this underlines is how unsure the rumor mill is even at this comparatively late stage of growth for RDNA 3 graphics playing cards. The playing cards might be out in round 4 months, after all, if hypothesis on the launch timeframe proves appropriate, and it nonetheless isn’t clear whether or not the elemental design for the subsequent-gen will sport a number of GPUs or not. All we are able to do is watch this house in the intervening time.

Whatever the case relating to the precise design, all the {hardware} leakers expect a robust flagship from AMD, and one that might properly run rings round Nvidia’s subsequent-gen Lovelace high canine for energy-effectivity (with Team Green rumored to be going very heavy on the facility utilization).
