Summary

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 dual-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

12.64%

of a leader's which is NVIDIA GeForce RTX 3090 Ti.

  • Passmark
  • GeekBench 5 OpenCL

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.

GeekBench 5 OpenCL

Geekbench 5 is a widespread graphics card benchmark combined from 11 different test scenarios. All these scenarios rely on direct usage of GPU's processing power, no 3D rendering is involved. This variation uses OpenCL API by Khronos Group.

Benchmark coverage: 9%
