The best open source alternative to GPU-Z is Open Hardware Monitor. If that doesn't suit you, our users have ranked more than 25 alternatives to GPU-Z and 12 is open source so hopefully you can find a suitable replacement. Other interesting open source alternatives to GPU-Z are CPU-X (by X0rg), hwinfo, Hardinfo and cpufetch.
The Open Hardware Monitor is a free open source software that monitors temperature sensors, fan speeds, voltages, load and clock speeds of a computer.
CPU-X is a free software that gathers information on CPU, motherboard and more.
hwinfo/libhd are used to probe for the hardware present in the system. It can be used to generate a system overview log which can be later used for support.
Hardinfo is a system information and benchmark tool for Linux. It shows detailed system info, including hardware, environment, and kernel. It can use lm_sensors and ACPI for temperature and battery information. It also has four CPU banchmarks and two FPU benchmarks.
cpufetch is a command-line tool written in C that displays the CPU information in a clean and beautiful way.
Examine is an app which gives you easy access to system information without needing to use the terminal, built for the COSMIC desktop.
