Intel Xeon Phi SE10X Photo Intel Knights Corner Photo
The Xeon Phi SE10X was 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. This device has no display connectivity, as it is not designed to have monitors connected to it. Xeon Phi SE10X is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 248 mm in length, and features a dual-slot cooling solution.

Card Notes

On November 15, 2011, Intel showed an early silicon version of a Knights Corner processor.

On June 5, 2012, Intel released open source software and documentation regarding Knights Corner.

In June 2012, Cray announced it would be offering 22nm 'Knight's Corner' chips (branded as 'Xeon Phi') as a co-processor in its 'Cascade' systems.
