The GRID K2 was an enthusiast-class professional graphics card by NVIDIA, launched on May 11th, 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. 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 paired 8 GB GDDR5 memory with the GRID K2, 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 (5 Gbps effective). Being a dual-slot card, the NVIDIA GRID K2 draws power from 1x 6-pin + 1x 8-pin power connector, 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.
