The GRID K2 was a enthusiast-class professional graphics card by NVIDIA, launched in May 2013. Built on the 28 nm process, and based on the GK104 graphics processor, in its GK104-895-A2 variant, the card supports DirectX 12.0. The GK104 graphics processor is an average sized chip with a die area of 294 mm² and 3,540 million transistors. GRID K2 combines two graphics processors to increase performance. It features 1536 shading units, 128 texture mapping units and 32 ROPs per GPU. NVIDIA has placed 8,192 MB GDDR5 memory on the card, which are connected using a 256-bit memory interface per GPU (each GPU manages 4,096 MB). The GPU is operating at a frequency of 745 MHz, memory is running at 1250 MHz.
Being a dual-slot card, the NVIDIA GRID K2 draws power from 1x 8-pin power connectors, with power draw rated at 225 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. GRID K2 is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 267 mm in length, and features a dual-slot cooling solution. Its price at launch was 5199 US Dollars.
