A ton of information on Intel’s upcoming Arc “Alchemist” gaming graphics cards has been released by SiSoftware. Intel’s Arc “Alchemist” will be separated into three series, A300, A500, and A700. The “A” of course stand for Alchemist. As you can guess the A300 will be entry-level, A500 will be mid-range performance, and the A700 will be high performance. All of Intel’s “Alchemist” GPUs will be built on TSMC’s N7 7nm silicon fabrication node.
So to start with the A300 series it will have 128 execution units, which works out to 1024 programmable shaders. Next is the A500 series that will have 384 execution units and 3072 shaders. Finally at the top is the A700 that has 512 execution units and 4096 shaders. The A300 series will have 6GB of 14 Gbps GDDR6 memory across a 96-bit wide memory bus for 192 GB/s of bandwidth. The A500 series will have 12 GB of 16 Gbps GDDR6 memory across a 192-bit bus for 384 GB/s of bandwidth. The A700 series will max out with 16GB of 16 Gbps GDDR6 across a 256-bit bus for 512 GB/s of bandwidth.
According to the data released for SiSoftware “Alchemist” parts will support real-time ray tracing and meet the full DirectX 12 Ultimate specification. As of right now we do not know how much mixed-function hardware is used to achieve this.
SiSoftware did test an entry-level Arc A380 graphics card (1024 shaders) in its Sandra GPGPU benchmark that uses native OpenCL code. In this test the A380 offered comparable performance to a GeForce GTX 1660 Ti “Turing” and was very close to the RTX 3050 “Ampere” and RX 6500 XT RDNA2.
The Intel Arc Alchemist series is expected to launch in the first half of 2022.
