About CoreFreq
CoreFreq is CPU monitoring software with BIOS-like functionality for 64-bit processors. It reports per-core frequencies, idle states, temperatures and power usage in fine detail, and supports a wide range of Intel and AMD generations, with code for x86_64, aarch64, ppc64le and riscv64.
It works through a kernel module and a background daemon, with DKMS configuration and a systemd service provided. That makes it suited to enthusiasts and people tuning or diagnosing hardware, rather than casual monitoring.

Alternatives to CoreFreq
Compare allSoftware that can replace CoreFreq for an important use case, and what changes if you switch.
s-tui
Terminal tool that graphs CPU frequency, utilization, temperature and power and can run a stress test.
s-tui graphs CPU frequency, temperature, power and load in a terminal with a built-in stress test, needs no kernel module, but gives less C-state detail.
CPU-X
Inspect processor, motherboard and system information on Linux.
CPU-X inspects processor and motherboard information on Linux with graphical, terminal and report modes, focusing on identification more than live C-state and power tuning.
PowerTOP
A Linux command-line tool for diagnosing power consumption and power management problems.
PowerTOP diagnoses power consumption by device and process on Linux, trading per-core frequency and C-state depth for power management tuning.
