NVIDIA Tesla K40c: specs and benchmarks

NVIDIA Tesla K40c


NVIDIA started Tesla K40c sales 8 October 2013 at a recommended price of $7,699. This is Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 12 GB of GDDR5 memory clocked at 6.01 GHz are supplied, and together with 384 Bit memory interface this creates a bandwidth of 288.4 GB/s.

Compatibility-wise, this is 2-slot card attached via PCIe 3.0 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 245 Watt.

It provides poor gaming and benchmark performance at 22.53 percent of a leader's which is NVIDIA TITAN V.
