AMD confirms Navi 31 and Navi 33 development of next-generation graphics cards
AMD has started preparing to release its next-generation GPUs, currently referred to as the Navi 3X or Navi 30 series. While there is plenty of life left in RDNA2, AMD has added support for Navi 31 and Navi 33 GPUs to the Radeon Open Compute Common Language Runtime (ROCclr), also known as ROCm Developer Tools.
Currently, Navi 31 is assumed to be AMD's next flagship GPU, with a multi-chip module (MCM) design and two graphics chiplets. AMD will continue to only have access to GDDR6 VRAM, but the Navi 31 is expected to offer up to 15,360 cores across an 800 mm² die with between 256 MB and 512 MB of Infinity Cache.
By contrast, Navi 33 should serve as a mid-range option with 5,120 cores on a 440 mm² die. Navi 33 is believed to have a monolithic design, distinguishing it from Navi 31. Its GDDR6 VRAM could be limited to a 128-bit bus too, halve the 256-bit bus afforded to Navi 31.
Additionally, AMD is thought to be developing Navi 32, a GPU that is closer in design to Navi 31 than Navi 33. Navi 32 is yet to appear on ROCclr, though. All Navi 3X GPUs are rumoured to be arriving in late Q2 2022.
