The RDNA 4 Navi 48 (“GFX1201”) GPU, which will likely be positioned above the smaller Navi 44 (“GFX1200”) and thus is expected to represent the largest expansion leg for the upcoming Radeon RX 8000, is now official that AMD developers have documented so Confirm it. In the new AMD ROCm Open Compute Platform commits, developers have documented the work on the new GPU for the first time.

This means that the two new expected larger RDNA 4 GPUs appear in official documentation from AMD for the first time, but both GPUs were previously announced through Linux patches. AMD's upcoming Radeon RX 8000 series graphics cards with Navi 48 (“GFX1201”) and Navi 44 (“GFX1200”) GPUs built on the RDNA 4 architecture have recently been hitting the rumor mill – according to PCGH.
On LLVM's GitHub project page Two graphics processors, GFX1200 and GFX1201, have been named for the first time and could be specified for the upcoming RDNA 4 architecture. According to current information, the previous numbering of the so-called graphics account ID looks like this:
- Graphics Account ID (“GC”)
- GFX101X = RDNA 1 with Navi 1X
- GFX103X = RDNA 2 with Navi 2X
- GFX11XX = RDNA 3 with Navi 3X
- GFX 115X = RDNA 3+ with Navi 3X
- GFX12XX = RDNA 4 with Navi 4X
While the graphics compute ID “GFX115X” is for the RDNA 3+ refresh architecture, which is especially expected in new APUs, and has not yet been used, the new graphics compute ID “GFX12XX” is now also being mentioned for the first time. These are RDNA 4 Navi 4X graphics processors.
