New in 0.8.21
- CPU and GPU panels on Overview. Each has its own dial, watts, and 1 min / 15 min / 1 hour averages. The GPU panel names the chip and the app using it most. Local AI models show here, not on the CPU.
- GPU colours the menu bar icon. Amber when the graphics chip averages 60% over a minute, red at 90%.
- Power by part (Energy tab). Watts for the CPU, graphics chip, Neural Engine and memory, read from the chip itself with no password, plus the rest of the Mac. Apple silicon only.
- Save power on the Graphics card. Graphics watts now, and one-click ways to cut them: optimise the screen, close a drawing browser tab, unload a local AI model, quit a background app using the GPU, or Low Power Mode on battery.
