The processor speed is below what was claimed.
The CPU runs at a base frequency of 3.7 GHz, a specification AMD will confirm meets. The advertised 4.2 GHz boost is flexible and might only appear under certain conditions. It usually works best for simple, single-thread operations. Avoid relying on it when the whole processor is heavily loaded.
Currently, AMD's performance isn't as consistent as it used to be. Back when the Ryzen CPUs advertised a maximum boost of 4.2 GHz, they often reached that speed regularly. "MAX BOOST 6.7 GHZ!!" – though not always reliable, it sometimes hit once a year under the right conditions.
The Ryzen CPUs definitely reached the advertised boost speeds. Most models released over the past five years, aside from very basic options, include higher boost clocks for single-threaded work.
It's been similar on both ends since Turbo became popular. Perhaps in the initial days, mobile makers were more inclined to customize for higher performance. With monitoring tools, you'll probably notice some cores reaching their peak clock speeds occasionally. Just remember, it won't stay there continuously.
CoreBoost is activated via BIOS and advertises a maximum speed of 4.2GHz, though you haven't reached those numbers during testing. Stress tests and games have consistently capped at around 3.9GHz. You regularly verify these figures using third-party tools.
Stress tests typically engage every core. Execute cinebench in single-core mode, you should increase it further.
