- Intel has discontinued the Clear Linux project, a high-performance Linux distribution optimized for x86_64 processors.
- Clear Linux was known for aggressive compiler tuning, kernel patches, and system-wide optimizations, leading in performance on both Intel and AMD hardware.
- Final benchmarks show Clear Linux is ~48% faster than Ubuntu 25.04 out-of-the-box on Intel Xeon Max servers.
- Clear Linux was heavily optimized for AVX-512 and newer Intel ISA features, making it ideal for high-performance computing.
- Benchmarks were conducted on a Supermicro Hyper SuperServer with dual Xeon Max 9468 processors, 512GB RAM, and NVMe storage.
- Clear Linux 43760 used Linux 6.15.5 kernel, GCC 15.1.1, and Python 3.13, while Ubuntu 25.04 used Linux 6.14, GCC 14.2, and Python 3.13.
- Ubuntu 25.04 defaults to 'schedutil' governor, which can impact performance compared to Clear Linux's 'performance' governor.
- Power consumption was monitored to assess the impact of Clear Linux's optimizations on CPU efficiency.
