GPU load, live, without Activity Monitor

Activity Monitor does not show GPU utilisation as a number you can glance at, and keeping it open costs you a window. The notch's system card carries GPU, CPU, temperature and memory in one row.

The number macOS keeps to itself

GPU utilisation comes from the accelerator's own performance statistics — the integrated-GPU figure both Intel and Apple Silicon expose — so it is the real device utilisation, not a guess derived from CPU load.

Temperature and memory beside it

CPU temperature, memory pressure and network throughput sit on the same card, with free space on every drive under them.

Rank by energy, not just CPU

Top Processes can sort by an Activity-Monitor-style energy impact — CPU time and wakeups together — which is what actually explains a fan spinning up or a battery dropping, where a raw CPU percentage does not.

Samples only while you are looking

The stats refresh while the card is on screen and stop when it is not, so a monitor you leave enabled is not a monitor you pay for all day — the measured figures are on the CPU and battery page.

Mac GPU monitor — FAQ

How do I check GPU usage on a Mac?

Activity Monitor has a GPU history window but no at-a-glance percentage. Notchy reads device utilisation from the accelerator directly and shows it on the notch's system card, next to CPU, memory and network.

Does it work on Intel Macs and Apple Silicon?

Yes. The utilisation figure comes from the performance statistics both architectures publish, with a fallback key for the driver generations that name it differently.

Does it show GPU temperature?

It shows CPU temperature alongside GPU utilisation. Not every Mac publishes a readable GPU temperature sensor, so a number that would be blank on many machines is not promised.

Can I see which app is using the most energy?

Yes — Top Processes can rank by energy impact instead of CPU, which surfaces a process that wakes constantly at low CPU but still drains the battery.

Does monitoring cost CPU itself?

It samples only while the card is visible and stops the moment it is not, so an idle notch costs nothing to keep it enabled.

Is a GPU monitor free in Notchy?

Yes. The whole system card — GPU, CPU, temperature, memory, network and drives — ships free.
