Running Intel's Clear Linux On AMD EPYC Rome? Still Significant Performance Uplift Over Ubuntu

Thursday 5th of September 2019 04:00:00 PM
The current AMD EPYC 7742 2P benchmarking that is happening at Phoronix is an interesting Linux/BSD operating system performance comparison. That's in the works while so far are some Ubuntu and Clear Linux numbers. Yes, Intel's open-source Clear Linux platform does run fine generally on AMD hardware -- including the new AMD "Rome" processors -- and generally does still run damn fast. Here is a look at Clear Linux on this 128 core / 256 thread server with Clear Linux against Ubuntu 19.04 as well as the upcoming Ubuntu 19.10.
