Rufus vs CPU-Z

Rufus: what it's good at

Rufus writes ISO images to USB drives to create bootable installation media for Windows, Linux and diagnostic tools. It is small, portable, notably fast, and the standard choice for making a Windows install stick.

• Creates bootable Windows and Linux USB media
• Notably faster than most alternatives
• Portable — no installation needed
• Handles UEFI and legacy BIOS

CPU-Z: what it's good at

CPU-Z reports precise details on your processor, motherboard, memory modules and graphics — the fastest way to find out what a machine actually contains before buying an upgrade or diagnosing a fault.

• Detailed processor identification
• Memory module and timing information
• Motherboard and BIOS details
• Built-in benchmark and stress test

Which should you choose?

Both are free, so the honest answer is that you can install either and decide for yourself — that is the advantage of free software over a paid trial.

Both run on Windows. Only CPU-Z supports Android. If open source matters to you, Rufus publishes its source code and CPU-Z does not.

We deliberately do not publish a star rating for either. We have no way to verify a rating that would be honest at scale, and an invented one would be worse than none — so we give you the facts and let you decide.
