Amds Flagship Rdna 3 Gpu May Not Have An All New Design After All

AMD’due south flagship RDNA 3 GPU may non have an all-new design after all

AMD’due south adjacent-gen flagship graphics carte (Navi 31, presumably the RX 7900 XT) may not become for a multi-scrap module (MCM) design sporting two separate GPUs as previously rumored, and could stick with a single GPU (every bit traditionally used) instead.

Before we go into this, we should make information technology articulate that the dual GPU rumor is just that – speculation that Team Carmine will build the flagship around a pair of GCDs (graphics compute dies) – as is the possibility that AMD might stay with the existing monolithic blueprint information technology has e’er used for its Radeon consumer graphics cards.

With that firmly in mind, several sources, including 3DCenter

spotted, the YouTuber underlines that several prominent Twitter leakers have joined in with this speculation), are now arguing it might be the example that Navi 31 volition run with just the one GCD.

The theory is that AMD could apply a configuration of ane master GCD (5nm), hooked upwards to vi memory chiplets (MCDs, built on 6nm), which would be a seven chiplet design.

RedGamingTech believes that we volition encounter Navi 31 sporting 12,288 cores, and that it’ll run with 24GB of VRAM, more the 16GB corporeality previously rumored (with a 384-bit retention interface).


Analysis: Two becomes one? Maybe, or maybe not…

As PC Gamer suggests, it may be the case that AMD has not been able to realize the dream of having 2 GPU fries working together seamlessly, so they’re simply seen as a unmarried GPU by the system – fugitive the complications and problems that have historically plagued the likes of SLI and CrossFire solutions whereby two graphics cards are linked together. (In those cases, yous don’t get twice the performance – the uptick may be much less than that, and other issues tin crop up likewise).

In short, it’s a thorny conundrum to tackle, and RedGamingTech asserts that they’re ‘pretty confident’ AMD has abandoned the 2 GCD configuration (which was also rumored to be for Navi 32, incidentally), and volition now run with a single GCD. RedGamingTech does get in clear that they’re not certain, though, and cautions against being also sure on this signal. And indeed some other leakers disagree that AMD is swerving away from the two GCD design for Navi 31.

argues that AMD is sticking to the previously rumored plan, asserting that the number of patents the visitor has regarding a new design with multiple GPU chips suggests this is the route Squad Blood-red intends to take. And also that having a single GPU with the theorized vi memory chiplets doesn’t make sense from a latency point of view (an of import consideration for gaming functioning).

What all this underlines is how uncertain the rumor manufactory is even at this relatively belatedly stage of development for RDNA 3 graphics cards. The cards could be out in around 4 months, subsequently all, if speculation on the launch timeframe proves correct, and it still isn’t articulate whether the key design for the next-gen will sport multiple GPUs or not. All nosotros can exercise is watch this infinite for the fourth dimension being.

Whatever the case regarding the verbal design, all the hardware leakers are expecting a powerful flagship from AMD, and one that could well run rings around Nvidia’s adjacent-gen Lovelace top dog for power-efficiency (with Squad Light-green rumored to be going very heavy on the power usage).
