I didn't necessarily mean CPU benchmarking software. Just anything that does a lot of work and is easy to measure.
Simple stuff that's pertinent: WinRAR, 7zip, VeraCrypt have integrated benchmarks in the menus.
More complex but still easy enough: Video encoding.
I suppose a popular simple GUI tool would be Handbrake
, and your codec of choice (x264 or x265).
May want to tweak the number of threads to see what's better for each CPU: 4 or 8 (or 6?).
No specific opinion on PassMark. It's another synthetic datapoint.

(I think the WP version is multithreaded?)
for memory/cache latency and bandwidth. Though not sure if the trial version shows everything.
