Alternatives to CPU-Z
A tiny freeware window that tells you exactly which processor, board and memory are in a Windows PC. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
CPU-Z
A tiny freeware window that tells you exactly which processor, board and memory are in a Windows PC.
Replacements
Listings that take over the same core job as CPU-Z.
HWiNFO
The deepest hardware report and sensor monitor on Windows, free for personal use.
HWiNFO reports even more hardware detail, including memory SPD data, and adds sensor logging and alerts, but commercial use requires a paid Pro licence.
CPU-X
Inspect processor, motherboard and system information on Linux.
CPU-X is free, open source under GPL-3.0 and runs on Linux with graphical, terminal and report modes, though some details need elevated access.
Speccy
Quick summary of a Windows PC's hardware and temperatures.
Speccy summarizes all PC hardware and temperatures on one page with shareable snapshots, has a free edition, but development has slowed considerably.
AIDA64 Extreme
Detailed hardware identification, sensor monitoring and benchmarking for Windows.
AIDA64 Extreme is paid, adding exportable hardware and software inventory, sensor monitoring and benchmarking to the identification CPU-Z provides for free.
Fastfetch
Prints a summary of your hardware, operating system and desktop in the terminal next to a logo, quickly and configurably.
Fastfetch is MIT-licensed and prints a hardware and OS summary in the terminal across Windows, macOS and Linux, but shows much less memory and board detail.
Hardinfo2
A graphical Linux tool that shows detailed system information and runs benchmarks.
Hardinfo2 gives a graphical hardware report plus benchmarks on Linux as open-source software, replacing CPU-Z's Windows and Android focus with Linux only.
inxi
A command-line system information tool that reports hardware, sensors, drivers and system details.
inxi reports hardware, sensors and drivers from a single command on Linux and the BSDs, with terminal output only instead of CPU-Z's small window.
Similar software
Related functionality, not a direct replacement.
GPU-Z
A tiny Windows utility that reports everything about your graphics card: clocks, memory type, bus width, sensors and BIOS.
HWMonitor
A Windows hardware monitor that reads voltages, temperatures, fan speeds, power and clock sensors.
Core Temp
Small utility that reads per-core CPU temperature on Windows.
Libre Hardware Monitor
Reads temperatures, fan speeds and voltages straight off the motherboard, and feeds them to other tools.
ThrottleStop
A small Windows utility that monitors and corrects Intel CPU throttling, especially on laptops.
OCCT
A PC stability, stress testing, benchmarking and hardware monitoring tool for Windows and Linux.
