CPU Z – The Ultimate Hardware Monitor

CPU-Z is one of the premier hardware monitoring programs available, providing fast access to information about your computer’s processor. The program quickly scans your system before displaying its findings in an easy to use tabbed interface.

Once you pass the validation window (your data will be anonymously shared with CPU-Z), the application reveals detailed information about your CPU, RAM, motherboard and graphics card in an easily understandable format. It includes tables with easily digestible results that make for an informative reading experience.


CPU Z offers an intuitive user interface and vast amounts of granular information, making it the ideal way to quickly gain access to detailed hardware data. The program gathers information about your CPU, motherboard, and random-access memory (RAM) for an overall overview of your computer system – making it popular among hardware enthusiasts, overclockers, and computer reviewers.

At first launch of CPU-Z, you will be asked to validate your PC. This creates an online report detailing anonymously all aspects of hardware including clock speeds. This data is then compiled and ranked within our validation database – however if desired you may opt out by checking off ‘Private validation’ at the bottom of the window.

Once logged in, the program will display a tabbed layout containing information on your CPU, motherboard and RAM. Each tab covers an aspect of its functionality or performance for example:

For instance, the CPU section provides information on your processor name and model along with its architecture, cores and clock speed. Furthermore, this program gives insight into its cache hierarchy which includes locations, sizes and technologies of all your cache locations. The Motherboard section displays your motherboard manufacturer, model and chipset while RAM gives insight into memory type size timings of your RAM on board your motherboard. Furthermore, this program also provides real time CPU usage monitor. Benchmarking allows you to keep track of your CPU’s performance and temperature when conducting resource-intensive tasks, especially during times when you overclock or run resource-intensive applications. The benchmarking section also offers a CPU stress test you can run for 10-15 minutes to check for stability – an invaluable feature when overclocking or running resource-intensive programs.


No matter if it’s an AMD eight-core Ryzen CPU that you just bought or an old Pentium chip that needs some new thermal paste applied, CPU-Z provides in-depth hardware monitoring capabilities. Along with reporting basic CPU details, system information and benchmark capabilities are all offered within this freeware utility program.

CPU-Z is an established program with many features that have made it a favorite among hardware enthusiasts. The application provides up-to-date data about your processor, memory and mainboard. Its user-friendly interface includes tabs for CPU Cache Memory SPD Graphics Bench.

The first tab of this program shows details about your CPU, such as its model and codename, core stepping and process, memory type and speed as well as physical core count. Furthermore, this tab displays L2 cache size, location and speed; its internal/external clock multipliers as well as total L2 cache size/location/speed details are displayed here as well.

Level 1 or L1 cache is an internal register in a CPU that stores instructions and data. The size of this memory typically ranges between 2KB to 64KB. When reading or executing certain instructions, a CPU searches first for their entry in L1 cache before checking main memory if none can be found there.

Level 2 (L2) cache is an additional memory containing smaller data sets that are stored for quick access by a CPU, usually via coprocessors with high-frequency alternative system bus links to ensure operations don’t lag due to main memory system congestion.


A motherboard is an essential piece of computer equipment that contains various chips that manage data flow in and out. Additionally, it contains ports for keyboard, mouse and cassette tape players – though often taken for granted or taken for granted by users.

CPU-Z is a freeware application that offers users detailed information about a PC’s processor (CPU), RAM and mainboard hardware. With this data at their disposal, CPU-Z allows users to optimize their hardware for overclocking or resource intensive apps – as well as prevent compatibility issues when installing new components.

The program’s straightforward design makes it simple and intuitive for novice or seasoned hardware enthusiasts to use, providing easy navigation between tabs to view hardware information about CPU, GPU, memory and more. Real-time monitoring capabilities are also included with real-time alerting capability and reports can be saved as text or HTML files for future reference.

On the CPU tab, this application displays various details about your processor’s core and caches, such as its model, speed, voltage and temperature. Furthermore, it offers important insights into its architecture – its internal and external clocks, clock multiplier and L1 and L2 cache information are displayed alongside core voltage detection as well as partial overclock detection capabilities.

Additionally, this tool provides in-depth details regarding your RAM’s size, type and timings through its “Memory” tab, making it invaluable to system builders and enthusiasts who seek to understand its capabilities and identify any problems which could affect performance. Likewise, its “Graphics” tab displays information regarding your graphics card manufacturer, driver version version number memory size compatibility; which helps determine if its graphics card fits within current software or hardware configurations.


CPU-Z is an invaluable tool when shopping for or upgrading an existing PC, providing in-depth information and performance data about all aspects of its hardware including CPU, motherboard and memory. Furthermore, its built-in benchmark enables you to compare system specifications among systems.

This application’s interface resembles most hardware monitoring programs, with tabs representing different aspects of your system – CPU Cache Mainboard Memory SPD Graphics Benchmark and Benchmark being some examples. Each tab provides information regarding hardware from CPU to graphics card in your computer system.

The CPU tab displays important details about your processor, such as its codename and processor type. It also shows its manufacturer and model numbers along with clock speed information. Furthermore, you can view other information about it such as its internal clock multiplier multiplier features or supported instruction sets.

Another feature found within the software is the CPU benchmark, which tests your processor in single-threaded tasks. While not measuring real world workloads, this benchmark does demonstrate modern CPUs’ capabilities by measuring instruction/branch predictability and memory accesses. Unfortunately, its results cannot fully represent all applications users may run on their computers.


The System Information Tool displays information about your graphics card such as its name, type, driver version and device ID. In addition, it shows details about its interface version, connection width, maximum support sidebanding capacity sideband frequency cache descriptor size speed as well as screen resolution and RAM memory usage. Available both for Windows and Android systems – simply download from its official website and install on your system to test its features – even conduct CPU benchmarks or stress tests through this simple to use app with its intuitive user interface!
