New AMD RDNA 3.5 GPU Target "GFX1152" Appears In Open-Source Linux Driver
When it comes to the RDNA 3.5 / RDNA 3+ integrated graphics found with upcoming AMD products, the graphics driver IP has been referred to as 'GFX1150' and 'GFX1151' of the AMD GFX 11.5 graphics IP
The AMD patch enabling GFX1152 for the AMDGPU shader compiler back-end confirms it's still for an APU as opposed to any discrete GPU refresh. At least from the compiler back-end perspective, GFX1152 is neatly identical to GFX1150 (GFX1151 is slightly different with "Feature1_5xVGPRs" set for having more VGPR registers) with just adding various new checks on conditional statements for this new variant. The GFX1150 / GFX1151 support in the open-source AMD Linux driver stack has been coming together for months but with GFX1152 only appearing now is likely for some later product or possibly some semi-custom silicon solution.
