Performance Rating

The H3C XG310 was a professional graphics card by Intel, launched on November 11th, 2020. Built on the 10 nm process, and based on the DG1 graphics processor, the card supports DirectX 12. The DG1 graphics processor is a relatively small chip with a die area of only 95 mm². H3C XG310 combines four graphics processors to increase performance. It features 768 shading units, 48 texture mapping units, and 24 ROPs, per GPU. Intel has paired 32 GB LPDDR4X memory with the H3C XG310, which are connected using a 128-bit memory interface per GPU (each GPU manages 8,192 MB). The GPU is operating at a frequency of 1050 MHz, which can be boosted up to 1100 MHz, memory is running at 2133 MHz.
