I received an Intel Core i5-12400F with full-core boost reaching up to 4.4GHz when idle. However, under any workload all cores instantly limit to 4GHz (3990MHz). It seems the CPU is adjusting this way due to temperatures, but that’s not true—my system reached a peak temperature of 51°C during summer while fully loaded. My main concern is: why does the CPU hit the maximum frequency of 4390MHz when idle, yet caps at 3990MHz under stress? Power plan is set to High Performance, and the motherboard is an ASUS PRIME B760 PLUS D4. I haven’t noticed any power restrictions in the BIOS. Some might say it’s not a big deal for 400MHz, but trust me, the GPU situation is even more confusing—please help clarify this.
You're all set. This will push it to its highest speed when idle. Any reduction while under load suggests the power limit, review the details in a more comprehensive source like HwInfo.
This behavior means that each processor core operates infrequently, with only a few percent active at any time. When the system reaches maximum demand, all available cores must perform at full capacity simultaneously, which can lead to power or thermal constraints. Under normal settings, Ryzen manages this by adjusting performance accordingly.
It seems the setup appears to match, but there’s no sign in the BIOS or settings that lets you bypass power restrictions, particularly since you have plenty of heat capacity.
The details about Intel non-K chips are unclear to me, but it seems you're suggesting limitations on performance improvements.
