For a long time, the first high-performance discrete graphics card DG2/Alchemist of the Intel Arc Ruixuan family has two cores, one is a 512-unit large core, and its performance is expected to be comparable to RTX 3070, and the other is a 128-unit small core, whose performance may be on par with GTX. 1650 SUPER, and more models from them.

Both the official rendering and the official product positioning map are these two cores. However, in the latest Linux graphics card system controller firmware (IGSCU FU) submitted by Intel, three cores of DG2 SOC1, SOC2, and SOC3 appeared at the same time, and the corresponding units were 512, 256, and 128. individual.
It is likely that the SOC3 256 unit version was added later and will be released later. In the previously exposed DG2 product line, there did appear a 256-unit version, corresponding to SKU3, with 128-bit 16GHz 8GB GDDR6 video memory, but it was generally believed or actually a castrated version of 512-unit at that time.
In terms of performance, the 256 units are just between the large and small cores in terms of specifications, so they are almost half of the large cores and twice that of the small cores, and are estimated to be comparable to the RTX 3060 or RX 6600.
It is also interesting that as early as September 2020, a 384-unit version of the PCB circuit diagram appeared. Combined with the official renderings of 512-unit and 256- unit versions, it is estimated that the core area of the SOC3 256-unit version is about 190-200 square millimeters.
The core area of SOC1 512 unit is 24.660×16.068≈ 396.24 square millimeters, and the core area of SOC2 128 unit is about 12.82×12.20≈ 156.40 square millimeters.
Anyway, hurry up and post it, can’t wait…
