Intel Core i5 10600K + Core i9 10900K Linux Performance Benchmarks
Written by Michael Larabel in Processors on 20 May 2020. Page 10 of 10. 64 Comments

Here is a look at the geometric mean of all the Linux gaming benchmarks conducted. The Core i9 10900K was basically tied with the Ryzen 9 3900X while the Core i5 10600K performed well too. Of 38 graphics/gaming tests ran, the Core i9 10900K won around 36% of them, the Ryzen 9 3950X won 52% of them, and the Core i9 9900KS won the rest (where the results were an effective tie). But when it comes to the more multi-threaded workloads commonly experienced on Linux, the Core i9 10900K was generally just running in between the Ryzen 9 3900X and Ryzen 9 3950X across the wide mix of workloads benchmarked:

Here is the geometric mean of all the CPU benchmarks carried out besides the gaming tests. The Core i9 10900K came out to being about 25% faster than the Core i9 9900KS but only 3% faster than the Ryzen 9 3900X. The Core i5 10600K meanwhile was striking mid-way between the Ryzen 5 3600X and Ryzen 7 3700X.

When running a wide range of CPU/system benchmarks and monitoring the reported CPU package power consumption using the Intel RAPL framework on Linux, the average CPU power consumption came in at 124 Watts... Right in line with Intel's marketing of a 125 Watt TDP rating. But at least according to the RAPL framework reporting based upon the Intel CPU metrics recorded, the actual peak power consumption of the CPU went as high as 380 Watts in extreme cases.

When cooling the Core i9 10900K with a Noctua NH-U9S with dual fans, the core temperature was 29 degrees at idle, 56 degree average under load, and peaked at 96 degrees. The i9-10900K hitting in the 90s was only encountered during the most demanding multi-threaded workloads, but if you will be hitting the CPU often, it may be wise with water cooling. More power/thermal benchmarks forthcoming with the i9-10900K.

Those wanting to see how their own Linux CPU performance compares to the various CPU/system benchmarks in this article, simply install the Phoronix Test Suite and run phoronix-test-suite benchmark 2005191-NI-NEWCOMPAR77 for your own fully-automated, side-by-side benchmark comparison. Additional Linux and BSD benchmarks forthcoming on Phoronix.
