Intel Arc Alchemist Graphics Card Lineup Detailed
SiSoftware put out the mother lode of information on Intel's upcoming Arc "Alchemist" gaming graphics card series, along with OpenCL compute performance of the entry-level Arc A380. The Arc series model numbering is "A" (Alchemist) followed by a number series. The A300 series makes up the entry-mainstream; the A500 series makes up the mid-performance segment; and the A700 series leads the pack with high-end SKUs. The "Alchemist" GPUs are built on the 7 nm silicon fabrication node at TSMC, the N7.
The A300 series is based on the smaller "Alchemist" series dies, with 128 EUs (execution units), which work out to 1,024 programmable shaders. The A500 series and A700 series appear to be carved out from the larger silicon. The A500 series has roughly 384 EU or 3,072 shaders. The top-dog A700 series has all 512 EU or 4,096 shaders enabled. Intel is tapping into industry-standard GDDR6 for dedicated graphics memory. The A300-series SKUs typically have 6 GB of 14 Gbps-rated memory across a 96-bit wide memory bus, for 192 GB/s of bandwidth. The A500 series parts have 12 GB of 16 Gbps-rated memory across a 192-bit bus, for 384 GB/s of bandwidth. The top A700 series maxes out the 256-bit memory bus with 16 GB of memory at 16 Gbps data-rate, for 512 GB/s bandwidth.
