Rumors of the next generation of AMD RDNA 3 ‘Navi 3X’ GPUs have already begun to hit the internet as reliable leaker, KittyYuko, who sent accurate information to Ampere GPUs months before release, has now posted the first alleged specifications for AMD’s Navi 33 GPU which gets the next generation Radeon RX graphics card for gaming.
AMD Navi 33 GPU for next generation Radeon RX graphics card reportedly has RDNA 3 ‘GFX11’ GPU IP with 80 computer devices and 5120 cores
According to KittyYuko, the AMD Navi 33 GPU is supposed to have the same specifications as the Navi 21 GPU, but will be based on the next generation of RDNA 3 GPU IP core. This means we get the same performance as the existing Big Navi 21 (RDNA 2) GPU in future mainstream graphics cards. This certainly sounds too good to be true, but given that AMD has promised huge performance gains with its RDNA 3 series of Radeon RX graphics cards, this may very well be the case.
Navi 33 (?) = Navi 21 + Next Gen IP Core

In terms of specifications, if Navi 33 matches Navi 21, we can expect a total of 80 computing units that will pack a total of 5120 stream processors if AMD keeps the number of CU cores to 64 SPs as the existing chips. What’s interesting now is that an earlier rumor had suggested that the Navi 31 GPU should also have 80 computing devices, but would be based on the new RDNA 3 IP. It seems that the 80 CU rumor could also be true, but those are not the full specifications that the chip will offer.
AMD Navi 31 chips end with an MCM solution and have dual 80 Compute Unit chip shapes, and each has 5120 cores. This will round up to a maximum of 160 computer units and a total of 10,240 stream processors. If that ends up being the case (and it looks more than ever that it would be), then we can definitely expect an 80 CU Navi 33 part. The Navi 32 SKU could end up with around 120-140 CUs, and it could also be a multi-chip module design.
This would compensate for a very hefty GPU design, and we can also expect it to be based on a brand new process node like TSMC’s 5nm. AMD has already patented an active brochiplet solution for its next-generation GPUs that comes with an integrated cache and connects the multiple dies found on Navi 3X (RDNA 3) GPUs, you can read more about that here.
You mean the highest level version of RDNA3?
Oh, it’s going to be a big bang.

I assume Ampere’s life will be extended at least until the end of next year.

AMD RDNA 3 ‘Navi 3’ GPU lineup of Radeon RX graphics cards will compete with NVIDIA’s own MCM GPUs based on either Ada Lovelace GPUs. From now on, the next generation parts are still not expected in late 2022 or early 2023, so treat this information with a light grain of salt.
