RDNA WorkGroup Processor (WGP) is a new unit introduced together with the RDNA 2 generation, where it always consists of two CUs (Compute Units), which today consist of 64 Stream processors. In the next generation, however, it would no longer have to contain classic CUs. Some people are talking about 30 WGP and others about 60 WGP, but this may simply stem from the fact that the Navi 31 is supposed to be a dual-chip GPU, so the information is not excluded.
We also learn about a total of up to 15,560 cores (three times that of Navi 21), which would mean that one WGP would be made up of 256 Stream processors / cores / shaders, whatever we call it, or twice the cores that make up one WGP in RDNA 2 chips.
In other words, RDNA 3 graphics chips would be divided only into WGP and no longer into CU, but the question is whether it is a design change that may affect performance and overall architecture, or it is just a cosmetic matter.
Next, the memory subsystem of the Navi 31 chip is discussed, which could still be only 256-bit, but this will probably apply to one chip with 30 WGP and it can also be expected that faster memories with higher throughput per pin (GDDR6X? ) and there is talk of a higher capacity Infinity Cache, which should at least double to 256 MB, and someone is talking about 512 MB. But even this can of course be connected with the topic of one and two chips in the GPU.
We are currently counting on AMD to launch its Navi 3 at the earliest in a year and rather by the end of next year, so at about the time when we expect NVIDIA Lovelace.
