CPU Core Load Reporter

Task Manager tells you the processor is busy. CPU Core Load Reporter shows you where.

The app draws your processor in its socket, with its real model name engraved on the heat spreader and a window onto the die. Every logical processor is a tile in that window, and each tile glows by how hard its thread is working: dark silicon when idle, amber when busy, a hot ember past the running-hot level. The busiest thread gets a soft bloom, so it is the first thing you see.

Click a tile and everything follows that thread: the headline reads its load, and the trace shows its last 60 seconds with the current, average and peak figures. Click the chip itself to go back to all threads. Arrow keys work too.

With nothing selected, the headline reads the total load as Idle, Light, Busy or Running hot, and names the busiest thread. The trace shows total load over the last minute, with the running-hot level marked on it.

Below the trace, the five programs using the most processor are listed with their icons, each with its share of all threads. A program that runs as many processes, like a browser, is added up into a single row, and the list refreshes every 2 seconds.

Under that are the processor's details: the model, the number of cores and threads, and the speed it is running at right now against its base speed, and how long Windows has been running. On hybrid Intel processors, performance and efficiency cores are counted separately and labeled P and E on the chip. On PCs whose firmware reports it, the voltage is shown as well.

Load comes from the same processor utility counter Task Manager uses, so the two agree. Speed is worked out the way Task Manager works it out.

Choose how often it updates, every half second, every second or every 2 seconds. Set the running-hot level anywhere from 50% to 100%. Show or hide the thread numbers. Pick light, dark or match Windows.

Scan the code in the app and your phone shows the same chip, every thread live, with the headline, the processor and the programs using it most. Tap a thread to follow it. It opens in your phone's browser: no app to install and no account. Your phone talks straight to your PC over an encrypted connection.

It needs no account and works with no connection. Nothing leaves your PC unless you connect your phone or send feedback, sign in to back up your settings or send feedback.
