Geekbench 6 for Linux ARM64 (Raspberry Pi, Asahi on Mac, etc.)

I was wondering if a version of Geekbench 6 for ARM64 or aarch64 devices is in the works. There was a nice preview tryout build available for RISC-V and ARM64 in the past for 5.4.4, but it never saw any updates.

It would also be nice to have to compare with Windows on ARM devices too, once the Windows ARM version of Geekbench is available.

    We've got a preview build for Geekbench 6 for Linux/AArch64 available here:

    We've also added a preview build page where you can get the latest version of each preview build:

    Thanks! I've been testing the 6.0.2 preview on Ubuntu 22.04, and noticed that at least on an Ampere Altra workstation with 92 CPU cores, there are two separate issues:

      1. Like with Geekbench 5, it identifies the CPU (model M96-28) as having 1 CPU, 1 core, and 96 threads.
      2. It never seems to complete the multicore tests, and it gets stuck on a different test each time—it seems like it only spreads the job over a few cores, minimally.

    Geekbench 5 score, for reference, on the exact same workstation:

    @geekbench please reach out if you need access to resources to debug this.

    Thank you for letting us know. We have access to an 80-core Ampere Altra server through Hetzner, so we'll attempt to reproduce it there.

    Thank you! Maybe at some point an Ampere Altra Dev Kit or Platform could find its way into your test lab too ;)

    I'm able to reproduce the issue on the 80-core system. What's interesting is that this wasn't an issue a week ago on the same system:

    This is going to be an interesting issue to debug.

    FYI I re-tested today on Ubuntu 22.04 on the (96-core) Ampere Altra, and it still gets stuck during multi-core tests. I noticed the wattage never exceeds 170W either, so I'm presuming the multicore tests aren't hitting all 96 cores, at least for long enough to make my power meter hit the heights it does during other multicore benchmarks.

    Nice that you provide an aarch64 binary, however, it can not run on asahi linux, as the page size is 16k by default, and jemalloc assumes 4k:

    $ ./geekbench_aarch64
    <jemalloc>: Unsupported system page size
    terminate called after throwing an instance of 'std::bad_alloc'
      what(): std::bad_alloc
    fish: Job 1, './geekbench_aarch64' terminated by signal SIGABRT (Abort)

    Geekbench 6.2.2 for Linux/ARM includes support for 16K pages, so should work on both Asahi Linux and Raspberry Pi 5:

    Let me know if you hit any issues with this build!

    Thx John, this works on asahi linux!

    Also tested it on a dual Ampere Altra Q80-30 system, stuck in multi-core test multiple times and gave up eventually

    Once in Background Blur (CPU seems running nothing, 100% for the cores but the power readings are low)
    Twice in Object Remover (CPU not running at all)

    It also seems to only utilize 100 cores/threads in the multicore test instead of all 160 cores/threads.

    I am testing on an AADP with 96 Cores and 192GB of RAM, it gets stuck at Running Background Blur with 78 cores pegged and won't progress after a long time waiting. The Q80 server from Equinix Metal also got stuck at the same place. The Raspberry Pi 5 and Mac Mini M1 with Asahi Linux all finished.

    Geekbench 5 finishes on all of them.

    Is there a way to get a version that is not preview for linux/ARM? I have a paid version of GB6 but i cannot apply the cdkey to this preview version.

    Is any Geekbench release for RISC-V on Linux available for testing ? Please help . thanks.
