This is our combined benchmark score.
Passmark
This is the most ubiquitous GPU benchmark. It gives the graphics card a thorough evaluation under various types of 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.

Pros & cons summary
| Performance score | 11.14 | 11.07 |
| Recency | 5 January 2013 | 27 June 2017 |
| Maximum RAM amount | 5 GB | 16 GB |
| Chip lithography | 28 nm | 14 nm |
| Power consumption (TDP) | 225 Watt | 300 Watt |
Tesla K20m has a 0.6% higher aggregate performance score, and 33.3% lower power consumption.
Instinct MI25, on the other hand, has an age advantage of 4 years, a 220% higher maximum VRAM amount, and a 100% more advanced lithography process.
Given the minimal performance differences, no clear winner can be declared between Tesla K20m and Radeon Instinct MI25.
