A CPU monitor that shows usage on every thread
A total CPU usage figure hides most of the story. A game stuck on one thread can max out a single logical processor while the overall number reads a modest 15%, and a background update can spread lightly across all of them. CPU Core Load Reporter is a CPU monitor that puts every thread in view at once, so you can tell which kind of busy you are looking at.
The processor is drawn as a chip seated in its socket, with the model name printed on the lid and the silicon visible underneath. Each logical processor gets its own square on that silicon, warming from dark through amber to ember as it works harder, and the busiest square picks up a soft bloom. Above the chip a headline sums up the state in one word, Idle, Light, Busy or Running hot, next to the percentage, and the hint below it names the busiest thread.
Load is read from the Processor Utility counter, the same one Task Manager uses, so the two agree rather than leaving you to work out which is right.
How to check CPU usage per core without Task Manager graphs
Task Manager can show logical processors, but only after you right-click the CPU graph and change its view, and then you get a wall of small identical charts. Here the chip is the view. To dig into one thread:
- Click its tile. The headline switches to that thread's load and the trace below draws its last 60 seconds, with Now, Avg and Peak.
- Use the arrow keys to step from thread to thread.
- Click the chip outside the tiles to go back to All threads.
- Open Settings to choose Update every (Half a second, 1 second or 2 seconds) and to move the Running hot above slider between 50% and 100%.
Find what is causing high CPU usage
Under the trace, a panel called Using the processor lists the five programs with the biggest share right now, each with its icon and its share of all threads. A program that splits itself into many processes, as browsers do, is counted as one row with the number of processes beside it, so the real culprit is not hidden behind a dozen small entries. The list refreshes every two seconds and only observes; it never closes anything.
Below that sit the processor's details: model, core and thread counts, live speed against base speed, uptime since Windows last started and, where the firmware reports it, the voltage.
P-cores and E-cores, labeled on the chip
On a hybrid processor, not every thread is equal. The app counts performance and efficiency cores separately, shows the split as P and E core totals, and badges each tile with P or E. That makes it easy to see whether a heavy task is running on the fast cores or has landed on the efficiency ones.
Watch your CPU from your phone
Click Watch on your phone and scan the code. The same chip opens in the phone's browser, with every thread live, the headline and the busiest programs, and you can tap a thread to follow it there too. Nothing needs to be installed on the phone. It is handy for keeping an eye on a long render or a game from across the room without alt-tabbing.
