NVIDIA Tesla K20c Image NVIDIA GK110 Image
The Tesla K20c is a high-end professional graphics card by NVIDIA, launched in November 2012. Built on the 28 nm process, and based on the GK110 graphics processor, in its GK110-885-KA-A1 variant, the card supports DirectX 12.0. The GK110 graphics processor is a large chip with a die area of 561 mm² and 7,080 million transistors. Unlike the fully unlocked GeForce GTX TITAN, which uses the same GPU but has all 2688 shaders enabled, NVIDIA has disabled some shading units on the Tesla K20c to reach the product's target shader count. It features 2496 shading units, 208 texture mapping units and 40 ROPs. NVIDIA has placed 5,120 MB GDDR5 memory on the card, which are connected using a 320-bit memory interface. The GPU is operating at a frequency of 706 MHz, memory is running at 1300 MHz.
Being a dual-slot card, the NVIDIA Tesla K20c draws power from 1x 6-pin + 1x 8-pin power connectors, with power draw rated at 225 W maximum. Tesla K20c is connected to the rest of the system using a PCIe 2.0 x16 interface. The card measures 267 mm in length, and features a dual-slot cooling solution. Its price at launch was 3,199 US Dollars.
