The original
AIDA64 Extreme
Detailed hardware identification, sensor monitoring and benchmarking for Windows.
Replacements
Listings that take over the same core job as AIDA64 Extreme.
HWiNFO
The deepest hardware report and sensor monitor on Windows, free for personal use.
HWiNFO is free for personal use and offers deep hardware reports with sensor logging and alerts, but commercial use needs a paid Pro licence and it stays Windows only.
Speccy
Quick summary of a Windows PC's hardware and temperatures.
Speccy gives a one-page summary of hardware and temperatures with shareable snapshots, has a free edition, but offers far less detail than AIDA64 and development has slowed.
HWMonitor
A Windows hardware monitor that reads voltages, temperatures, fan speeds, power and clock sensors.
HWMonitor focuses on voltages, temperatures, fan speeds and clocks with a free edition and ARM64 builds, but has no benchmarking and puts graphs in the paid PRO version.
CPU-Z
A tiny freeware window that tells you exactly which processor, board and memory are in a Windows PC.
CPU-Z is free and portable, reporting CPU, board and memory SPD details, with an Android version, but it does not track temperatures or run broad benchmarks.
Libre Hardware Monitor
Reads temperatures, fan speeds and voltages straight off the motherboard, and feeds them to other tools.
Libre Hardware Monitor is free, open source under MPL-2.0 and portable, reading motherboard, CPU, GPU and drive sensors, but it lacks detailed inventory reports and benchmarks.
Open Hardware Monitor
Open-source reader for temperature, fan and voltage sensors.
Open Hardware Monitor is free and open source and runs on Windows and Linux, but upstream development stopped and newer chipsets are often unrecognised.
OCCT
A PC stability, stress testing, benchmarking and hardware monitoring tool for Windows and Linux.
OCCT combines stress testing, benchmarking and hardware monitoring, runs on Windows and Linux, and is free for individuals, but focuses less on detailed inventory reports.
Hardinfo2
A graphical Linux tool that shows detailed system information and runs benchmarks.
Hardinfo2 is a free, open source Linux app that combines system information with benchmarks, replacing AIDA64's Windows-only reports for Linux users.
Also worth comparing
These listings name AIDA64 Extreme as their own alternative, so the relationship runs both ways.
Core Temp
Small utility that reads per-core CPU temperature on Windows.
AIDA64 Extreme is paid software combining sensor monitoring with detailed hardware inventory and benchmarking, a much larger tool than Core Temp's CPU-only readout.
CPU-X
Inspect processor, motherboard and system information on Linux.
AIDA64 Extreme is a paid Windows-only tool with detailed hardware inventory, exportable reports, sensor monitoring and benchmarking, unlike the free open-source CPU-X.
GPU-Z
A tiny Windows utility that reports everything about your graphics card: clocks, memory type, bus width, sensors and BIOS.
AIDA64 Extreme covers the GPU within a full hardware and software inventory with exportable reports and benchmarking, but it is a paid licence with a time-limited trial.
SIW
Windows system information tool that reports hardware, software, network and sensor details.
AIDA64 Extreme is also paid and Windows only, adding benchmarking and sensor output to external displays alongside detailed exportable hardware and software reports.
Similar software
Related functionality, not a direct replacement.
Hard Disk Sentinel
Drive health, temperature and lifetime monitoring for HDDs and SSDs.
Fastfetch
Prints a summary of your hardware, operating system and desktop in the terminal next to a logo, quickly and configurably.
ThrottleStop
A small Windows utility that monitors and corrects Intel CPU throttling, especially on laptops.
