Intel Core i5 8400 Linux Performance
Written by Michael Larabel in Processors on 5 October 2017. Page 5 of 5. 12 Comments

The Core i5 8400 does run well with the multi-threaded Darktable RAW photography program.

And Coffee Lake does very well with its Java performance, no pun intended.

The timed LLVM compilation performance of the Core i5 8400 is right behind the Ryzen 7 1700.

Lastly with 7-Zip compression, the Core i5 8400 is in line with a Core i7 4790K Haswell CPU.

Thanks to Intel transitioning Core i5 CPUs to representing a hexa-core design, the Core i5 8400 is quite a capable sub-$200 USD CPU (it's expected to retail for around $180). The similarly priced Ryzen 5 1600 has the benefit of SMT and larger L3 cache, but as shown in these benchmarks with the processors I have available, in several instances the Core i5 8400 was competing with the Ryzen 7 1700 and sometimes even between the Ryzen 7 1700 and Ryzen 7 1800X. Where the Core i5 8400 does particularly well is in the single-threaded benchmarks and where the workloads do better with Intel's superior IPC performance.

Those wishing to see how their own Linux system(s) compare side-by-side to the results found in this article, simply install the Phoronix Test Suite automated benchmarking software and run phoronix-test-suite benchmark 1710057-TY-KAFK8400876.

See more tests in our Core i7 8700K benchmarking while additional Coffee Lake Linux testing will be forthcoming on Phoronix.
