CoreFreq vs TuxClocker

CoreFreq is free Linux CPU-monitoring software with BIOS-like controls for 64-bit processors. It reads frequencies, ratios, performance counters, instructions per cycle, C-states, temperature, and documented core-voltage readings. The interface shows processor features, brand and architecture strings, plus a topology map including caches. Its driver exposes controls for Turbo Boost, power management, thermal limits, prefetchers, and hardware-controlled performance states. A daemon and command-line client provide monitoring views and JSON-encoded system information. Listed architectures include Intel and AMD families, Arm A64, RISC-V RV64, and PowerPC64 LE. Requirements include Linux kernel 3.3 or newer and GNU C Library. Installation can use source builds or packages for several distributions. The project is GPL-2.0 licensed and uses shared memory between its kernel module and user-space component. Some virtual machines may hide required registers. Driver signing is required when kernel signature verification is enabled. The interface renders best in ASCII or VT100 terminals.

TuxClocker is a GNU/Linux hardware monitoring and control program made up of a D-Bus daemon and a Qt graphical interface. It can handle any number of devices at once, with users selecting device nodes to read or change properties. NVIDIA features include fan, clock, and power-limit controls, plus temperature, utilization, and VRAM monitoring; voltage settings and readings are available for 600–900 series GPUs under Xorg. AMD features include fan and clock control, performance parameters, voltage and VRAM monitoring, and voltage-frequency curve editing on applicable GPUs. CPU tools cover frequency and utilization monitoring, governor settings, frequency limits, power usage, and energy-power preferences. Installation options include a prebuilt release tarball and packages for openSUSE Tumbleweed. NVIDIA editing requires Coolbits, while AMD editing requires the amdgpu.ppfeaturemask boot parameter. Optional dependencies provide vendor support, and python-hwdata can improve AMD device names. The project is licensed under GPL-3 only and lists GNU/Linux as its current platform focus.
