Intel Xeon Phi 3120A
The Xeon Phi 3120A is a high-end 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. Unlike the fully unlocked Xeon Phi 7120P, which uses the same GPU but has all 244 shaders enabled, Intel has disabled some shading units on the Xeon Phi 3120A to reach the product's target shader count. It features 228 shading units, 57 texture mapping units and 57 ROPs. Intel has placed 6,144 MB GDDR5 memory on the card, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 1100 MHz, memory is running at 1250 MHz.
We recommend the Intel Xeon Phi 3120A 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 3120A 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 1,695 US Dollars.

|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.
