Benchmarking OpenMandriva 4.0 Alpha - The First Linux OS With An AMD Zen Optimized Build

The Stress-NG kernel tests were another case of mixed performance but at least in some of the tests seeing better performance with OpemMandriva's Znver1 build.

OpenMandriva's Redis package did appear a little bit faster with its Znver1 optimizations.

The Blender performance was flat.

The PHP performance did speed up when using OpenMandriva's Znver1 build over the generic x86_64 packages.

Surprisingly, the znver1 build was booting slower.

Of 62 different benchmarks I ran on these two versions of OpenMandriva Lx 4.0 Alpha 1, the Znver1 build was faster in 34 cases while the generic x86_64 build was faster the other 28 cases. Overall, the performance was really a toss-up and based upon these initial results hard to declare whether the Znver1 build is really worthwhile. There were a few cases where the current Znver1 performance was slower, but at least for the most part in cases where it wasn't a clear winner at least offered comparable speed to the generic x86_64 performance. Even in the cases of Znver1 winning, the benefits were not as profound like what we see with Clear Linux on Intel hardware but that was not to be expected considering the differences in their approach and engineering efforts. As the official OpenMandriva Lx 4.0 release nears, I'll be back with an even greater selection of benchmarks and on multiple AMD Zen systems to get a better feeling for this Znver1-optimized Linux build.
