Overview
CPU-Z is a software application designed to provide information on some of the key features of the microprocessors found in personal computers.

What is CPU-Z used for?
CPU-Z attempts to determine the exact operating parameters and clock frequency of various Intel microprocessors, including:
The application also determines the manufacturer, model and family of the CPU, codename (where applicable), core stepping and process (where applicable) as well as other computer information such as Memory Type, BIOS Revision and Serial Number.
CPU-Z also deciphers the full signature of some processors that were initially only partially decipherable using other utilities.
More recent versions of CPU-Z also include support for decoding the second-generation Enhanced Intel SpeedStep technology (EIST) and AMD PowerNow! technologies.
Interface
The information presented by CPU-Z is displayed in tabs. By default, version 1.99 presents six tabs: CPU, Mainboard, Memory, SPD (Serial Presence Detect), Graphics and Bench. Each tab is further divided into groups of items which can be selected to display higher degrees of detail.
All Features
- Processor name and vendor
- Core stepping and process
- Processor package
- Processor current core voltage
- Internal and external clocks, clock multiplier
- Partial overclock detection
- Processor features, including supported instructions sets.
- L1 to L3 cache information : location, size, speed, technology.
- Motherboard information : name, vendor, BIOS, chipset, memory, AGP.
- Memory information : size, type, timings, specifications.
- A complete report, that includes CPUID, MSR, PCI device list, SPD, DMI.
