64 Bit Gentoo Raspberry Pi 3 Benchmarks

Thu Feb 02, 2017 2:28 pm

Yesterday I received an E-mail from sakaki, who has released Bootable 64-bit Gentoo image for the Raspberry Pi 3, with Linux 4.10.0, and has compiled and run some of my RPi benchmarks, suggesting co-operation in publishing results (glad to do it). I produced a bootable SD card and ran my first benchmarks successfully, that were compiled with gcc-6, via OpenSuse.

Gentoo was running using “on demand” frequency control between 600 MHz idle and consistent 1200 MHz when running CPU benchmarks (unlike OpenSuse). Reference to both will be in:

The initial 32 bit benchmarks have been compiled to run at 64 bits and results are reported in my Raspberry Pi Benchmarks thread:

The initial benchmarks were Whetstone, Dhrystone, Linpack and Livermore Loops, with performance gains of up to 40%.
