It is always better to benchmark with actual programs than it is with benchmark utilities. Geekbench's claims as a cross-platform test are also not really validated.

For example, let's check out the M1 Mini review that Anandtech did, specifically these two pages:

https://www.anandtech.com/show/16252/mac-mini-apple-m1-teste... https://www.anandtech.com/show/16252/mac-mini-apple-m1-teste...

According to Geekbench, the M1 handily beats the 5950X in single-threaded work. However, according to Cinebench 1T and spec2017, the 5950X is faster at single-threaded. Who is "correct"?

The answer is a much more simple "look at the benchmark results that matter for your workloads." A good review will cover benchmarks of a variety of workloads as a result so you can figure out which matters to you. Which is never geekbench, since nobodies workload is ever geekbench. So a good review will tend to not include geekbench rather than include it, unless they just don't have better ways to compare whatever they're testing.
