Intel Xeon Phi SE10X Image Intel Knights Corner Image
The Xeon Phi SE10X is a professional graphics card by Intel, launched in November 2012. Built on the 22 nm process, and based on the Knights Corner graphics processor, the card supports DirectX 11.1. The Knights Corner graphics processor is a large chip with a die area of 350 mm² and 5,000 million transistors. It features 244 shading units, 61 texture mapping units and 61 ROPs. Intel has placed 8,192 MB GDDR5 memory on the card, which are connected using a 512-bit memory interface. The GPU is operating at a frequency of 1100 MHz, memory is running at 1375 MHz.
Being a dual-slot card, its power draw is rated at 300 W maximum. Xeon Phi SE10X is connected to the rest of the system using a PCIe 3.0 x16 interface. The card measures 248 mm in length, and features a dual-slot cooling solution.
