- Max video memory 6 GB
- Memory type GDDR5
- Memory clock speed 5200 MHz
- Maximum resolution
Summary
NVIDIA started Tesla K20Xm sales 12 November 2012 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. 6 GB of GDDR5 memory clocked at 5.2 GHz are supplied, and together with 384 Bit memory interface this creates a bandwidth of 249.6 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. No additional power connector is required, and power consumption is at 235 Watt.
It provides poor gaming and benchmark performance at
of a leader's which is NVIDIA GeForce RTX 4090.

Overall score
This is our combined benchmark performance rating. 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.
- Passmark
- GeekBench 5 Metal
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.
Benchmark coverage: 24%
GeekBench 5 Metal
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 Metal API by Apple.
