The Quadro K4000 was a enthusiast-class professional graphics card by NVIDIA, launched in March 2013. Built on the 28 nm process, and based on the GK106 graphics processor, the card supports DirectX 12.0. The GK106 graphics processor is an average sized chip with a die area of 221 mm² and 2,540 million transistors. Unlike the fully unlocked GeForce GTX 660, which uses the same GPU but has all 960 shaders enabled, NVIDIA has disabled some shading units on the Quadro K4000 to reach the product's target shader count. It features 768 shading units, 64 texture mapping units and 24 ROPs. NVIDIA has placed 3,072 MB GDDR5 memory on the card, which are connected using a 192-bit memory interface. The GPU is operating at a frequency of 810 MHz, memory is running at 1404 MHz.
Being a single-slot card, the NVIDIA Quadro K4000 draws power from 1x 6-pin power connectors, with power draw rated at 80 W maximum. Display outputs include: 1x DVI, 2x DisplayPort. Quadro K4000 is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 241 mm in length, and features a single-slot cooling solution. Its price at launch was 1269 US Dollars.
