NVIDIA Tesla K40c: specs and benchmarks
NVIDIA started Tesla K40c sales 8 October 2013 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. 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 11.56% of a leader's which is NVIDIA GeForce RTX 4090.

APIs supported by Tesla K40c, sometimes including their particular versions.
Synthetic benchmark performance of Tesla K40c. The combined score is measured on a 0-100 point scale.
Combined synthetic benchmark score
This is our combined benchmark performance score. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.
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.
Benchmark coverage: 25%
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%
