AMD’s next-gen flagship graphics card (Navi 31, presumably the RX 7900 XT) might 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 a substitute.
Earlier than we go into this, we should always make it clear that the twin GPU rumor is simply that – hypothesis that Staff Crimson will construct the flagship round a pair of GCDs (graphics compute dies) – as is the chance that AMD would possibly stick with the present monolithic design it has all the time used for its Radeon shopper graphics playing cards.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), at the moment are arguing it is likely to be the case that Navi 31 will run with simply the one GCD.
The idea is that AMD may use a configuration of 1 foremost 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).
Evaluation: Two turns into one? Possibly, or possibly not…
As PC Gamer suggests, it might be the case that AMD has not been in a position to notice the dream of getting two GPU chips working collectively seamlessly, so that they’re solely seen as a single GPU by the system – avoiding the issues and issues which 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 efficiency – the uptick could also be a lot lower than that, and different points can crop up too). Briefly, 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 positive 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 concerning a brand new design with a number of GPU chips suggests that is the route Staff Crimson intends to take. And in addition that having a single GPU with the theorized six reminiscence chiplets doesn’t make sense from a latency standpoint (an essential consideration for gaming efficiency). 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, in spite of everything, if hypothesis on the launch timeframe proves appropriate, and it nonetheless isn’t clear whether or not the basic design for the next-gen will sport a number of GPUs or not. All we will do is watch this house in the intervening time.Regardless of the case concerning the precise design, all of the {hardware} leakers predict a strong flagship from AMD, and one that might properly run rings round Nvidia’s next-gen Lovelace prime canine for power-efficiency (with Staff Inexperienced rumored to be going very heavy on the ability utilization).
