More Power Consumption / Perf-Per-Watt Figures For Intel Kabylake On Linux
Written by Michael Larabel in Intel on 12 February 2017 at 09:00 AM EST. 1 Comment
In yesterday's Core i3 2100 "Sandy Bridge" vs. Core i3 7100 "Kabylake" comparison I included all of the power consumption and performance-per-Watt results. If you are looking for additional power numbers from other Kabylake CPUs, here is some additional data.

As some extra numbers uploaded to were extra power consumption, performance-per-Watt, and raw performance numbers for the Pentium G4600, Core i3 7100, and Core i7 7700K on the same motherboard/system. I hadn't used the Core i5 7600K in this comparison since I wanted to avoid swapping it out to reduce any extra stress on this bent processor.

Ubuntu was used for this round of tests albeit with switching to the newer Linux kernel and such; Antergos was used yesterday in the i3-x100 CPU comparison.

All other hardware/software components were kept the same during testing.

We've featured these three Kabylake CPUs in other Linux comparison articles, but it's always fun looking at the latest figures.

Especially when factoring in the performance-per-Watt with the Phoronix Test Suite polling a WattsUp Pro AC power meter.

And taking advantage of other Phoronix Test Suite extra features.

The power consumption was interesting.

There is also some CPU thermal data with all three processors being cooled by an Arctic Cooling Freezer i11.

Go stop by for all the benchmark data. To compare your own system's performance, simply install the Phoronix Test Suite and run phoronix-test-suite benchmark 1702117-RI-KABYLAKEP69. Set the MONITOR=cpu.temp environment variable prior to running PTS if you also want to compare your CPU thermal performance.
