Intel ACM-G12 GPU discovered with 16 Xe cores and 256 EUs

The Intel Graphics Compiler on GitHub suggests that the company is preparing to release a third ACM GPU after the ACM-G10 and ACM-G11. For reference, the Intel Graphics Compiler is open source and an LLVM based compiler for OpenCL. Currently, the Graphics Compiler supports platforms from Gen8 through to Gen12 graphics.

As the screenshots below, a recent patch added support for ACM-G12, a GPU that Intel did not reveal at its Arc Graphics presentation. While the patch refers to the GPU as ACM-G12, it also outlines that G12 is 'DG2 256'. In other words, the ACM-G12 has 256 Execution Units (EUs), slotting in between the ACM-G10 and ACM-G11, which have 512 and 128 EUs, respectively.

Additionally, this would mean that the ACM-G12 has 16 Xe cores, plus 2,048 FP32 cores. Unfortunately, it remains to be seen when Intel will announce the ACM-G12 and in what form. VideoCardz speculates that the ACM-G12 could arrive as an Arc A500 desktop graphics card. Currently, Intel has only announced a mobile Arc A500 graphics card, which utilises the ACM-G10 instead. Alternatively, VideoCardz suggests that the ACM-G12 could debut in a workstation GPU, expected to be released in Q3 2022.
