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

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.
These opinions are my own, not of AMD.
> Designed from the ground-up for cross-platform comparisons, Geekbench 5 allows you to compare system performance across devices, operating systems, and processor architectures. Geekbench 5 supports Android, iOS, macOS, Windows, and Linux.
But it seems like there are a lot of other options.

PC hardware sites are probably less concerned with "cross-platform" benchmarks. As long as the system hardware and operating system are the same, varying only the component you're testing, you can test with any benchmark that runs on the system.
