My Windows 7 desktop pc built about 2 years ago.
Gigabyte Z97X-UD5H motherboard

Memory 32768 MB DDR3 SDRAM 666MHz
AMD Radeon R9 200 Series
I have no idea what the test results mean : )
I have a regular hard drive that spins at 7200rpm. Maybe I can goose the score up a bit if I have a SSD drive.
Single-Core Score 4494
Multi-Core Score 13299
Geekbench 4.1.0 Tryout for Windows x86 (64-bit)
OpenCL Score
81547
It means that, according to the charts above, your machine is being beaten by seven of the iMacs in single core performance bench marks, and nine of them in multicore bench marks.
It's beaten by six of the iMacs in the graphics processor bench marks.
I hope this helps in understanding what the test results mean. ;^)
