Geekbench only have an ARM Linux tool for one version of their GeekBench 2, and none in their latest and greatest GeekBench 3 (The non trial version of their tool sells for $13, so the market for an ARM Linux benchmark tool is tiny, they do have Android and iOS covered)
 
Here is how I ran the tests on some ARM Linux machines that I own:
$ wget http://cdn.primatelabs.com/geekbench-2.4.2-LinuxARM.tar.gz
$ tar xvfz geekbench-2.4.2-LinuxARM.tar.gz
$ cd dist/Geekbench-2.4.2-LinuxARM
$ ./geekbench --benchmark
(when the benchmark finishes running they give a URL to where they have uploaded the results on their website)
 
Other trial versions can be downloaded from the following URL's:
http://cdn.primatelabs.com/Geekbench-2.4.2-Linux.tar.gz
http://cdn.primatelabs.com/Geekbench-2.4.2-WindowsSetup.exe
http://cdn.primatelabs.com/geekbench-2.4.2-LinuxARM.tar.gz
http://cdn.primatelabs.com/Geekbench-3.3.2-Linux.tar.gz
http://cdn.primatelabs.com/Geekbench-3.3.2-WindowsSetup.exe
 
The Trial versions only test the 32 bit instruction set and the results can only be viewed online. And most version fails at detecting multiple cores and threats them as threading opportunities to parallel the testing. The testing only looks at CPU performance, so even though a NVIDIA Jetson TK1 has a good CPU and an amazing GPU, this is not reflected in the results.
