The Performance-Per-Watt Of NVIDIA Fermi To Pascal, AMD R700 To Polaris Benchmarks

The Dota 2 4K performance results, for those that don't remember the numbers from the earlier article. Of course, 4K was rather stressing on the older hardware but was needed for being able to stress the newer GPUs.

A look at the system power consumption during this benchmark.

So with the performance-per-Watt with Dota 2 it's fun to see how things have evolved. From the Radeon HD 4890 to R9 Fury the perf-per-Watt is up by 6.2x while from the GTX 460 to the GTX 1080 it's up by 11.6x, or 9.2x if wanting to just compare the GTX 460 to GTX 1060. Hopefully Vega will do better on the perf-per-Watt front as right now the GTX 1080 is delivering 1.87x the perf-per-Watt of the R9 Fury under Linux.

The Phoronix Test Suite was also recording the CPU utilization during testing too. You can see here at least with Dota 2, the NVIDIA driver does utilize more of the CPU during testing albeit delivers much better results.
