CPU-Z: Know Exactly What’s Inside Your Computer in Seconds
Solves in one sentence: Bought a used computer or built a new one and want to know if the specs match what the seller claimed? CPU-Z shows all your hardware info clearly the moment you open it.
Whether you’re a PC enthusiast or a regular user, there’s always that moment when you want to know your exact CPU model, memory frequency, or motherboard chipset. Windows’ built-in system info is too basic, and Device Manager is too scattered.
CPU-Z is designed for this exact scenario — open it and you’ll know, no extra steps needed.
What Is CPU-Z?
CPU-Z is a free hardware information detection tool. It reads detailed information about your system’s CPU, motherboard, memory, graphics card, and other hardware, displaying it in a clean interface.
The problem it solves: Get your computer’s complete hardware configuration within seconds, without opening the case.
What Info Can You See?
