Geekbench is not intended for benchmarking large workstations. Look at how the web site actually describes the benchmark. It's for phones and laptops and similar devices. A test mode that uses a machine in a way that is only relevant to high-end workstation or server use would be actively harmful to the suitability of Geekbench for its intended audience of consumer hardware and consumer users.

You can use geekbench 5 in that case. But given that they deprecated that, it might be harder to compare to others.
