CPU-Z is a freeware system information and hardware monitoring tool developed by CPUID. It provides detailed information about your computer's central processing unit (CPU), motherboard, memory (RAM), graphics card, and other hardware components. Since its initial release in 2004, CPU-Z has become one of the most trusted and widely used hardware identification tools in the world, with over 100 million downloads globally.
Unlike many system information tools that require installation and may include bundled software, CPU-Z is completely free, lightweight (approximately 2MB), and available in both installer and portable versions. The portable version can run directly from a USB drive, making it perfect for technicians, system builders, and anyone who needs to quickly identify hardware on multiple systems.
CPU-Z reads information directly from your hardware's identification registers and system firmware, providing accurate, real-time data about your system's components. This makes it an essential tool for hardware verification, system diagnostics, performance optimization, and technical documentation.
CPU-Z uses advanced detection algorithms to read hardware information directly from your system's components. It accesses CPU identification registers, memory SPD (Serial Presence Detect) chips, motherboard BIOS data, and graphics card firmware to gather comprehensive hardware specifications.
The application displays this information in an organized, tabbed interface that makes it easy to find what you're looking for. Each tab focuses on a specific hardware component: CPU, Caches, Mainboard, Memory, SPD, Graphics, and Bench. The Bench tab includes a built-in CPU benchmark tool that allows you to test and compare your processor's performance.
CPU-Z updates regularly to support the latest processors from Intel and AMD, ensuring accurate detection of new hardware. The software is compatible with Windows 7, 8, 10, 11, Windows Server, and Android 4.0 and later. It requires minimal system resources and runs efficiently even on older hardware.
Verify that you received the correct hardware components when purchasing a new computer or upgrading your system. CPU-Z helps you confirm CPU model, RAM capacity and speed, motherboard specifications, and graphics card details match what you paid for.
Quickly identify hardware components when troubleshooting system issues, updating drivers, or checking compatibility. CPU-Z provides the exact model numbers and specifications needed for finding the right drivers and support resources.
Understand your system's capabilities to optimize settings, verify overclocking results, and ensure optimal memory configuration. CPU-Z's real-time monitoring and benchmarking features help you get the most from your hardware.
Export detailed hardware reports in TXT or HTML format for technical support, system documentation, upgrade planning, or warranty purposes. CPU-Z reports include all hardware information in a professional, easy-to-read format.
Essential tool for PC builders and system integrators. Verify component compatibility, check BIOS versions, ensure proper memory configuration, and document builds for clients. CPU-Z is the first tool many professionals install on new systems.
Use CPU-Z's built-in benchmark tool to test CPU performance, compare with other processors, verify overclocking stability, and measure performance improvements after upgrades or optimizations.
CPU-Z supports virtually all modern processors from Intel and AMD, including desktop, mobile, and server CPUs. The software is regularly updated to support the latest processor releases, typically within weeks of new CPU launches. CPU-Z can identify and display detailed information for:
CPU-Z supports all memory types including:
Visit the official CPUID website to download the latest version of CPU-Z. You can choose between the installer version (recommended for permanent installation) or the portable ZIP version (perfect for USB drives or temporary use). Both versions provide identical functionality.
The download is completely free, requires no registration, and contains no adware or spyware. CPU-Z is a trusted tool used by millions of users worldwide.
If you downloaded the installer, run it and follow the on-screen instructions. The installation process is quick and straightforward. If you downloaded the portable version, simply extract the ZIP file to any folder and run cpuz.exe directly.
The portable version is ideal if you don't have administrator rights, want to run it from a USB drive, or prefer not to install software on your system.
Launch CPU-Z and explore the different tabs. Start with the CPU tab to see your processor information, then check the Memory tab for RAM details, and the Mainboard tab for motherboard information. Each tab provides comprehensive details about that component.
CPU-Z displays information in real-time, so you can see your CPU's current clock speed, which changes based on workload. This is normal behavior for modern processors with power-saving features.
Use the Tools menu to export your hardware information as a TXT or HTML report. These reports are perfect for documentation, technical support, or sharing system specifications. The HTML format is particularly useful as it creates a nicely formatted, easy-to-read report.
Reports include all information from every tab, making them comprehensive documentation of your system's hardware configuration.
CPU-Z reads information directly from hardware registers and firmware, ensuring accurate, reliable data. Unlike software that relies on Windows Device Manager or system information, CPU-Z provides detailed technical specifications that match manufacturer specifications exactly.
This accuracy is crucial when verifying hardware purchases, troubleshooting compatibility issues, or documenting system configurations for technical support.
At just 2-5 MB in size, CPU-Z is incredibly lightweight and launches instantly. It uses minimal system resources and doesn't slow down your computer. The portable version can run from a USB drive without leaving any traces on the system.
This makes CPU-Z perfect for quick hardware checks, system diagnostics, or running on systems with limited resources.
CPU-Z is completely free with no hidden costs, no subscription fees, and no premium versions. There are no ads, no bundled software, and no data collection. It's freeware in the truest sense of the word.
This makes it accessible to everyone, from individual users to large organizations, without any licensing concerns or budget constraints.
CPU-Z is actively maintained and regularly updated to support the latest hardware. New processor releases are typically supported within weeks, ensuring CPU-Z remains current with the latest technology.
Updates are free and easy to install, and the software notifies you when new versions are available, though you can continue using older versions if preferred.
Yes, CPU-Z is completely safe. It's developed by CPUID, a reputable software company, and has been used by millions of users for over 20 years. The software contains no malware, adware, or spyware. It's available directly from the official CPUID website and trusted download sources.
No, CPU-Z works completely offline. It reads information directly from your hardware and doesn't need internet access for basic functionality. The only time an internet connection is useful is for downloading updates or using the online validation feature to compare your hardware with an online database.
No, CPU-Z cannot overclock your CPU. It's a monitoring and information tool, not an overclocking utility. However, CPU-Z is excellent for monitoring your CPU during overclocking - you can watch real-time clock speeds, voltages, and use the benchmark tool to verify overclocking results. To actually overclock, you'll need to use your motherboard's BIOS or dedicated overclocking software.
This is completely normal! Modern CPUs use power-saving features that reduce clock speed when idle to save energy and reduce heat. When you run a demanding application or the CPU-Z benchmark, you'll see the speed increase to the advertised boost clock. Check the "Specification" field in CPU-Z to see your CPU's base and boost clock speeds. The "Core Speed" field shows real-time speed, which varies based on workload.
Both versions are identical in functionality. The installer version creates shortcuts, integrates with Windows, and is better for permanent installation. The portable (ZIP) version can run directly from any folder without installation - perfect for USB drives, temporary use, or when you don't have administrator rights. Choose based on your needs; many users keep both versions.
Latest version includes support for newest Intel and AMD processors, improved accuracy, and enhanced benchmark features.
