The Tesla K20Xm 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, 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. It features 2688 shading units, 224 texture mapping units, and 48 ROPs. NVIDIA has paired 6 GB GDDR5 memory with the Tesla K20Xm, which are connected using a 384-bit memory interface. The GPU is operating at a frequency of 732 MHz, memory is running at 1300 MHz (5.2 Gbps effective). Being a dual-slot card, its power draw is rated at 235 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Tesla K20Xm 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 7699 US Dollars.

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.)
