Can anyone explain the inconsistency of the effective clock (max values only) in this HWiNFO Score please?

Cpu core load, clock speed drops during idle and boosts up when needed.

Depends on core load, more demanding loads will yield higher effective clocks

Don't use HWInfo for Ryzen because of misreporting. For accurate monitoring, use Ryzen Master

Forgot to mention this is after Cinebench. Surely that should use all cores right?

when set to all cores, yes

but they will throttle when they hit max temp (around 100c)
or are limited by the mobos vrm power config

the ryzen core design changed on this gen, each core will have its own max limits, and the cpu will use the best cores as often as it can, when windows or programs are not limiting or assigning cores

Wait, this is new to Zen 3, or was it improved? My Zen 2 also seems to behaving this way, but I'm not sure how much of it is Windows' doing; I just noticed those two or three cores seem to be the ones that always get the preferred treatment.

zen 2 uses ccx modules with cores sharing cache in their own banks

with z2 ccx design the fastest cores were not always on the same ccx and needed to transfer cache from one bank to another

zen 3 changed the ccx design, all are cores now share the same cache bank

Oh, yeah, that much I knew. I was just confused because the "preferred core" bit seemed like it was happening on my CPU as well but you mentioned it as a new thing, but I wasn't sure if this was merely coincidental and Windows' doing or something. My prior CPU was a Core i5 2500K under Windows 7 and I didn't notice the behavior there.

I see the same inconsistencies with my 5600X with HWInfo64. HWmonitor won't show clock frequencies and Ryzen Master doesn't show clocks either nor can you manually overclock in advanced view because the cores aren't showing at all.
BIOS is up-to-date as are chipset drivers. We will have to wait for these programs to get updates.

But the load will be gone and the core usage and thus clocks and temps settle down soon as such a test is over. Plus Ryzen highest clocks (Turbo Boost) will depend quite a bit on your temps. Keeping it cooler should help boost higher automatically and also help be more consistent.
