CoreFreq vs G-Helper

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.

G-Helper is a free, portable Windows control tool for Asus laptops and handhelds. It brings together performance, fan, GPU, battery, and RGB controls in a single executable that does not require installation. Performance modes are Silent, Balanced, and Turbo, with built-in fan curves; GPU modes are Eco, Standard, Ultimate, and Optimized. Dedicated GPU controls include core and memory clock offsets, GPU power, Dynamic Boost, and temperature limits. Automation can change performance mode, GPU mode, screen refresh rate, and keyboard-backlight timeout according to AC or battery power. An in-game overlay reports FPS, CPU and GPU temperatures, fan RPM, and power draw. Selected Asus mice, keyboards, and headsets can have lighting, bindings, equalizers, and battery settings. The app checks Asus for model-specific BIOS and driver updates and uses the Asus System Control Interface driver plus BIOS-stored operating modes. It requires the .NET 10 Desktop Runtime and that Asus driver. The desktop application says it does not collect or transmit personal data.
