AMD’s RX 6000 series graphics cards are still quite modern and it seems that this is not the time to talk about their successors. After all, we should get acquainted any day with the new Radeon RX 6600 XT and Radeon RX 6600 units belonging to the mid-range. It just so happens that we know almost everything about these systems today. In turn, 3DCenter has summarized all the leaks so far about next year’s modules based on the RDNA3 architecture. It turns out that there may be significant design changes to the current Radeons – if you believe insiders, the new graphics cards will be deprived of classic computing units. So what will replace them?
The AMD RDNA3 graphics chip is divided into so-called working groups. It is claimed that this solution will not significantly affect the complexity of the system.
AMD RDNA 3 – A leading Radeon graphics card with a NAVI 31 core can deliver three times higher performance than the Radeon RX 6900 XT
It seems that many sources unanimously say that the new generation of the flagship graphics processor called Navi 31 can have up to 15,360 stream processors. However, according to Beyond3D forum member Bondrewd, the Navi 31 GPU will feature 30 RDNA WGP (Workgroup Processors) modules. This GPU is currently believed to consist of two MCM arrays. At 15,360 stream units, this means that each group contains 256 shaders (FP32 cores/stream processors), which is double what RDNA2 WGP offers. Reports about the lack of computing units are no less interesting. The layout is divided into so-called working groups, which seems like an interesting solution, but it is claimed that it will not significantly affect the complexity of the design.
AMD NAVI 33 – Radeon graphics card based on the RDNA 3 architecture with specifications similar to the Radeon RX 6900 XT
There are also rumors about VRAM that will be on board the Navi 31 GPU. It’s true that there are no memory capacity leaks for the next flagship Radeon just yet, but we’ll likely see a maximum 256-bit bus again. More importantly, however, the Infinity cache is expected to expand from 128MB in RDNA2 to 256MB or even 512MB in RDNA3. This seems to explain the use of the same bus. However, it will take some time to confirm this news – it is likely that the Radeon RDNA3 graphics cards will debut in the third or fourth quarter of 2022.
