GPU
The Tesla K20c was an enthusiast-class professional graphics card by NVIDIA, launched on November 12th, 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. 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 paired 5 GB GDDR5 memory with the Tesla K20c, 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 (5.2 Gbps effective).
Being a dual-slot card, the NVIDIA Tesla K20c 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. Tesla K20c is connected to the rest of the system using a PCI-Express 2.0 x16 interface. The card measures 267 mm in length, and features a dual-slot cooling solution. Its price at launch was 3199 US Dollars.

GK110 GPU Notes
| NVENC: 1st Gen NVDEC: 1st Gen PureVideo HD: VP5 VDPAU: Feature Set D L1 Cache is configurable from 16 KB up to 48 KB per SMX GK110 has 5 GPCs each capable of 8 pixels per clock. This limits complete GPU to 40 pixels per clock and because of that it can't feed all 48 ROPs when they all require data at the same time. Additional ROPs however can be used for MSAA (because it doesn't require additional data from rasterizers, while giving more work to ROPs.)
