Linux Power Efficiency Of Skylake, Broadwell, Haswell & Kaveri Compared
The Xonotic results were similar to the Tesseract and Unigine Valley test results except that in terms of raw performance the A10-7870K had managed a few frame lead.
Turning over to some CPU benchmarks, under the FFTW workload the Core i5 6600K was the fastest processor but ended up coming in with a lower performance-per-Watt than the Core i7 CPUs of the Haswell and Broadwell era.
