Rainmeter performance monitor12/13/2023 ![]() ![]() ![]() Displays processor model and clock speed.Supports symmetric multiprocessing (SMP) and non-uniform memory access (NUMA) architectures (skins for up to 4 CPUs or 4 NUMA nodes are provided, but more can be added).Displays CPU utilization for an unlimited number of CPUs and processors with up to 64-cores/128-threads each.I've taken the most widely used gadgets and re-imagined them in a new suite of Rainmeter Gadgets. It is a platform that enables skins to run on the desktop. Rainmeter is a free, open-source application for Windows PCs. Gadgets aren't supported in Windows 8 or Windows 10 without hacks and workarounds and often they break after applying Windows Updates. Unfortunately, with the deprecation of the Gadget platform and outright banning of gadgets by some corporate policies, these gadgets have become obsolete.

The important thing to note is all these numbers are "correct", it just depends how you want to measure "Usage". Something like that, I'm doing this from memory so I may have it backwards. If you do the math (quickly!) you'll see that "% CPU Usage" x (100 / "%Maximum Frequency") will give you a number that more closely matches Rainmeter and HWiNFO. If you look at Windows' Resource Monitor (yet another info source), the top of the CPU pane shows "% CPU Usage" and "% Maximum Frequency". If you look at the individual logical cores, the values will be correct, but the overall number is something different. Unfortunately, it appears that Task Manager's overall utilization number is somehow being "un-scaled" and reports some weird value. In this case overclocked cores report 100+% performance, while underclocked cores will never get to 100% even if they are fully occupied. Task Manager uses this new performance counter for "usage". This counter better works with dynamically clocked cores to report the amount of work being done. In Windows 8 and later, a new performance counter was added, Processor Information > % Processor Utility. The time-based counters both report 100% in each mode, so Microsoft made a change. For example, if a CPU is running overclocked at 100%, it is doing WAY more work than if it was running 100% at the base clock speed. In Windows 8, Microsoft changed the way they measure "usage", because time-based monitoring doesn't mean as much when CPU's are automatically overclocking and underclocking. HWiNFO and Windows 7's task manager also used this as well. If you look are PerfMon, this is the Processor > % Processor Time counter. (I wondered about this, same as you.)įirst, Rainmeter's CPU measure and the UsageMonitor plugin with the CPU alias, both pull the CPU usage from a source that uses a timed-based performance counter. Just looking for more info and a way to maybe hopefully get a more accurate reading.Īttached is just once example but they never really seem to match up, HWiNFO and RainMeter get pretty close most of the time but still pretty off from Task Manager.Īctually, all those sources do align once you realize where the data is coming from and how it is being reported. I was working on a cpu meter and I noticed that Windows Task Manager, Rainmeter, and HWiNFO all report different CPU usage values, is it because of how they are calculated or where they get their info from? I'm not really sure who to trust here, Task Manager is pretty high at the moment and fans are blowing hard so im leaning towards believing the higher number reported by Task manager vs HWiNFO and Rainmeter (Processor=0).
