![]() ![]() The old time-based counters never exceed 100%, but the utility-based counter will reflect >100% when the CPU is running in turbo/boost mode. This will flip the skin around to use the old Win7 time-based counters, and you'll see it now acts like your other CPU skins.Īn easy way to tell what any skin is using without digging into the code is to max out your CPU and look to see if the performance exceeds 100%. If you want to see the difference, open the CPU Meter Settings skin (click the wrench icon in the upper right corner) and check the option "Use Legacy Mode". This is why the Gadgets CPU Meter matches Windows 11's Task Manager, it uses the new utility performance counters. And Turbo Boost drives the processor above 100% of its nominal speed, and allows the processor to exceed 100% capacity.Īny Rainmeter skin that uses CPU measures, or UsageMonitor measures that use the CPU alias, will not report CPU performance accurately (or at least, not the same way Task Manager or Resource Monitor does). With the redesigned Task Manager, the first processor is shown to be running at 50% capacity, whereas the second processor is shown to be running at 100% capacity. Both appear to be doing the same amount of work: 100% of their capacity. Before this change, under the time-based performance counters (used in Windows 7 Task Manager), those two processors clocked differently. A processor that's running 50% of the time and clocked down to 50% frequency performs only half the work of a processor that's running 100% of the time at 100% frequency. This change was intended to provide a more accurate representation of how much work the system is handling, and the utility counters do just that. The utility performance counters take into account the processor performance state and Turbo Boost-based enhancements to measure and normalize the work that's being done by the CPU. The old time-based performance counters measure the percentage of time that the processor is busy, whereas the new utility performance counters measure how much work the processor actually performs. The difference between the two counter types concerns how they measure the actual work that the processor performs. (Windows Resource Monitor will show values over 100%.) Task Manager's CPU Performance tab will truncate (or clamp) CPU utilization values to 100%. ![]() ![]()
