NVIDIA started Tesla K20m sales 5 January 2013 at a recommended price of $3,199 . This is a Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 5 GB of GDDR5 memory clocked at 1.3 GHz are supplied, and together with 320 Bit memory interface this creates a bandwidth of 208.0 GB/s.

Compatibility-wise, this is a dual-slot graphics card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 267 mm. One 6-pin and one 8-pin connectors are required, and power consumption is at 225 Watt.

Passmark

This is the most ubiquitous GPU benchmark. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.
