Just look at the driver if you don't believe me. I already linked data structure descriptions on Reddit. Download 100.8885, open iga64.dll, start at offset 0x22fab8 and subtract 0x180000c00 from every pointer. Shouldn't be that hard!
Do you think it makes sense that TGL-H Xe is 12_5 based while Alder Lake which comes later than TGL-H is 12_2 based?
