Performance Rating

The Tesla K20m was an enthusiast-class professional graphics card by NVIDIA, launched on January 5th, 2013. 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. 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 K20m 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 K20m, 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).
