The GRID K340 is a high-end professional graphics card by NVIDIA, launched in July 2013. Built on the 28 nm process, and based on the GK107 graphics processor, the card supports DirectX 11.2. The GK107 graphics processor is an average sized chip with a die area of 118 mm² and 1,270 million transistors. GRID K340 combines four graphics processors to increase performance. It features 384 shading units, 32 texture mapping units and 8 ROPs per GPU. NVIDIA has placed 4,096 MB GDDR5 memory on the card, which are connected using a 64-bit memory interface per GPU (each GPU manages 1,024 MB). The GPU is operating at a frequency of 950 MHz, memory is running at 900 MHz.
We recommend the NVIDIA GRID K340 for gaming with highest details at resolutions up to, and including, 1920x1080.
Being a dual-slot card, the NVIDIA GRID K340 draws power from 1x 8-pin power connectors, with power draw rated at 225 W maximum. GRID K340 is connected to the rest of the system using a PCIe 3.0 x16 interface. The card measures 267 mm in length, and features a dual-slot cooling solution. Its price at launch was 3,299 US Dollars.
