Intel Xeon Phi 7120P Image Intel Knights Corner Image
The Xeon Phi 7120P is a high-end professional graphics card by Intel, launched in June 2013. 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 16,384 MB GDDR5 memory on the card, which are connected using a 512-bit memory interface. The GPU is operating at a frequency of 1238 MHz, which can be boosted up to 1333 MHz, memory is running at 1375 MHz.
We recommend the Intel Xeon Phi 7120P for gaming with highest details at resolutions up to, and including, 5760x1080.
Being a dual-slot card, its power draw is rated at 300 W maximum. Xeon Phi 7120P 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. Its price at launch was 4,129 US Dollars.
