NVIDIA Tesla K20c: specs and benchmarks

NVIDIA Tesla K20c

Summary

NVIDIA started Tesla K20c sales 12 November 2012 at a recommended price of $3,199. This is Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 5 GB of GDDR5 memory clocked at 5.2 GHz are supplied, and together with 320 Bit memory interface this creates a bandwidth of 208.0 GB / s.

Compatibility-wise, this is 2-slot 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.

It provides poor gaming and benchmark performance at 19.67 percent of a leader's which is NVIDIA TITAN V.
