The CPU manager is composed of up-to 9 tabs. Availability depends on Android version and the use of custom kernels
Summary – shows CPU+GPU model information

CPU controls – allows controlling CPU or shows detail state of CPU on non-rooted devices
Voltages – allows controlling CPU voltages – requires root and custom kernel
Governors – allows controlling CPU governor configuration (requires root)
MPDecision – allows controlling how kernel activate CPU cores – requires root and custom kernel
Graphics – shows various graphics of CPU/GPU data (load, temperature and frequencies)

GPU controls – allows controlling GPU or shows detail state of GPU on non-rooted devices
Frequencies – shows CPU frequency timings, eg how long each frequency is used

Thermal – allows controlling CPU thermal throttling – requires root and custom kernel
