Summary

NVIDIA started Tesla K20Xm sales 12 November 2012 at a recommended price of $7,699. This is a Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 6 GB of GDDR5 memory clocked at 5.2 GHz are supplied, and together with 384 Bit memory interface this creates a bandwidth of 249.6 GB/s.

Compatibility-wise, this is dual-slot card attached via PCIe 3.0 x16 interface. Its manufacturer default version has a length of 267 mm. No additional power connector is required, and power consumption is at 235 Watt.

It provides poor gaming and benchmark performance at

Passmark

This is probably the most ubiquitous benchmark, part of Passmark PerformanceTest suite. It gives the graphics card a thorough evaluation under various 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.
