Last week Friday the unfortunate news came down that Intel was discontinuing their Clear Linux project effective immediately. For the past ten years Intel software engineers have been crafting Clear Linux as a high performance distribution that is extensively optimized for x86_64 processors via aggressive compiler tuning, various patches to the Linux kernel and other packages, and a variety of other optimizations throughout the operating system. For years Clear Linux has led Linux x86_64 performance not only on Intel desktop/mobile/server hardware but on AMD systems too. Here is a final look at the Clear Linux performance on the Intel side compared to the performance of the latest Ubuntu 25.04 release.
