A patch to the open source Intel Graphics Compiler is said to have revealed the name of a third Arc GPU along with ACM-G10 and ACM-G11. Intel is probably planning a third GPU called ACM-G12, which could have 16 Xe cores and 2048 FP32 units.
Intel officially introduced two new Arc GPUs last week, the ACM-G10 and G11. These are new names for previously common DG2 GPUs. There are no limits to the names, because in addition to ACM-G10 or DG2-G10, SOC1 and DG2-512 are also particularly familiar to this GPU. DG2-G10 is said to be used in Intel’s Linux software development and is likely to be a combination of internal and public GPU names.
Is a third Arc GPU coming?
Now another name seems to have surfaced, suggesting that Intel hasn’t played all its aces yet and may have a third GPU up its sleeve, dubbed the DG2-256 or ACM-G12. The first name is said to have been mentioned in mid-March and has now appeared in a patch for the Intel Graphics Compiler for OpenCL and Ubuntu OS, which is said to have been released at the same time as the announcement of Arc Alchemist for notebooks. As is well known, this day only the ACM-G10 and ACM-G11 were presented, which leads to the conclusion that either there are only these two GPUs or that they are intended for the mobile segment and the third GPU of the group. It is not.

So the ACM-G12 could be used as a desktop GPU or perhaps a graphics unit for workstations, which is expected in Q3. In any case, Intel has not yet published exact technical data. Since the Intel Graphics Compiler patch includes the name DG2-256, the ACM-G12 can be expected to have 256 execution units, which are also known as Xe Vector Engines in Intel parlance. According to Videocardz, the ACM-G12 should also have 16 Xe cores and 2048 FP32 units, which is half the units of the flagship ACM-G10 GPU. With the width of the memory controller, 128 bits would be conceivable, but 192 bits would also be an option.
Ultimately, it’s unclear why Intel dropped the ACM-G12 when introducing mobile Arc GPUs and instead just limited itself to the other two copies. It is possible that the GPU will simply be released later, as according to Videocardz, public software development for SOC3 only started a few weeks ago.
