The H3C XG310 is a professional graphics card by Intel, launched in November 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 77 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 900 MHz, which can be boosted up to 1550 MHz, memory is running at 2133 MHz.
Being a single-slot card, the Intel H3C XG310 draws power from 1x 8-pin power connector, with power draw rated at 300 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. H3C XG310 is connected to the rest of the system using a PCI-Express 3.0 x16 interface.
