The GRID K1 was a enthusiast-class professional graphics card by NVIDIA, launched in March 2013. Built on the 28 nm process, and based on the GK107 graphics processor, in its GK107-450-A2 variant, the card supports DirectX 12.0. The GK107 graphics processor is an average sized chip with a die area of 118 mm² and 1,270 million transistors. Unlike the fully unlocked GeForce GT 640 OEM, which uses the same GPU but has all 384 shaders enabled, NVIDIA has disabled some shading units on the GRID K1 to reach the product's target shader count. GRID K1 combines four graphics processors to increase performance. It features 192 shading units, 16 texture mapping units and 16 ROPs per GPU. NVIDIA has placed 16,384 MB DDR3 memory on the card, which are connected using a 128-bit memory interface per GPU (each GPU manages 4,096 MB). The GPU is operating at a frequency of 850 MHz, memory is running at 891 MHz.
Being a dual-slot card, the NVIDIA GRID K1 draws power from 1x 6-pin power connectors, with power draw rated at 130 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. GRID K1 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 4140 US Dollars.
