Intel Has More P-State Changes Coming For Linux 4.12

Tuning the P-State CPU frequency scaling driver for the Linux kernel feels like a never-ending process. While it's been around for years and continues to be refined, for some Intel CPUs on some workloads, the CPUFreq scaling driver leads to be better performance and even Intel's own Clear Linux distribution is using CPUFreq by default. With Linux 4.12, more intel_pstate revisions are taking place.

Benchmarks Of Many ARM Boards From The Raspberry Pi To NVIDIA Jetson TX2

For some weekend benchmarking fun, I compared the Jetson TX2 that NVIDIA released this weekend with their ARM 64-bit "Denver 2" CPU cores paired with four Cortex-A57 cores to various other ARM single board computers I have access to. This is looking at the CPU performance in different benchmarks ranging from cheap ~$10 ARM SBCs to the Raspberry Pi to the Jetson TX1 and Jetson TX2.
