Tesla K20s: specs and benchmarks

VS

Summary

NVIDIA started Tesla K20s sales 18 February 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. No additional power connector is required, and power consumption is at 225 Watt.
