The Performance-Per-Watt, Efficiency Of Intel/AMD/NVIDIA GPUs On Open-Source Drivers
Written by Michael Larabel in Graphics Cards on 5 June 2014. Page 6 of 6. 28 Comments

There isn't too much to gain out of the GPU temperature data due to the variety of different AIB vendor graphics cards used and some of them having non-stock heatsink fans, unless you're just looking at comparing the average power temperature of a particular GPU against your own graphics card. The NVIDIA GPU temperatures were obviously lower since they were running at their boot frequencies.

You can benchmark your own system against all of this data by running MONITOR=cpu.usage,gpu.temp,sys.power PERFORMANCE_PER_WATT=1 phoronix-test-suite benchmark 1406039-KH-MONITORIN10 after having installed the Phoronix Test Suite.

Coming next week will be benchmarks on these many graphics cards using the proprietary AMD and NVIDIA Linux graphics drivers.
