Power Consumption & Thermal Testing With The Core i9 7900X On Linux

Next up was a run of PostgreSQL, where the 20 thread Core i9 7900X came out well in front of the other tested CPUs.

Air cooling was sufficient for all of the tested CPUs while the i7-7700K strangely peaked higher than the i9-7900X.

The Core i9 7900X had a average power draw of 110 Watts and a peak of 141 Watts while running PostgreSQL compared to the Ryzen 7 1800X at 97 / 124 Watts and the i7-7700K at 69 / 91 Watts.

But the higher power use of the Skylake-X was still enough to give it leading performance-per-Watt with this being one of the multi-threaded tests.

With the Apache web server test, the i9-7900X actually loses out to the i7-7700K.

Air cooling is still working out for the i9-7900X with the i11 and NH-D9L.

For this self-hosting Apache test, the power use of the i9-7900X was only a few Watts more than the other CPUs.
