🧠 CPU-Z · Processor & System Encyclopedia
📌 Overview
CPU-Z is a freeware system profiling and monitoring application developed by CPUID. It gathers detailed information about the main components of your computer: processor (name, vendor, core stepping, instruction sets), motherboard (BIOS version, chipset, PCIe configuration), memory (RAM type, size, timings, SPD), and graphics (basic GPU info). With a footprint below 5 MB, no installation required (portable version available), and support from Windows 95 to Windows 11, CPU-Z has been the industry reference for CPU identification and validation for over two decades.
⚙️ Core Features & Technical Specifications
| CPU Identification | Processor name, code name, core stepping, revision, TDP, core voltage, clock multiplier, bus speed, and full list of supported instruction sets (MMX, SSE, AVX, AVX‑512, AMX, etc.). |
|---|---|
| Cache & Core Topology | Detailed L1, L2, L3 cache sizes and associativity; number of physical cores, logical threads; core parking status and real‑time per‑core frequency. |
| Motherboard & BIOS | Manufacturer, model, chipset (Intel / AMD), southbridge, BIOS brand, version, date, and UEFI status. Also PCI‑Express link configuration. |
| Memory (RAM) Analysis | Type (DDR4, DDR5, LPDDR5…), size, channel mode (dual, quad), NB frequency. SPD tab reads JEDEC and XMP / EXPO profiles including timings (CAS, RAS, tRFC), voltage, and manufacturer (Samsung, Hynix, Micron). |
| Real‑time Monitoring | Per‑core clock frequency, core voltage, memory frequency, and load graphs (visible in the latest versions). Includes a validation tool to generate online proof of your system specifications. |
| Portable & Lightweight | No registry changes; runs from USB stick. Supports 32‑bit and 64‑bit Windows, and also offers an Android version (CPU-Z for Android) for mobile SoC analysis. |
🆕 What's New (v2.13 – June 2025)
- Intel: Added support for Arrow Lake‑S refresh, Panther Lake engineering samples, and Intel Core Ultra 300 series (Lunar Lake‑M).
- AMD: Granite Ridge (Ryzen 9000 X3D), Strix Halo with hybrid memory detection, Turin server APUs.
- Memory: Improved DDR5 SPD hub reading and CAMM2 module detection.
- General: Enhanced validation checks for overclocking databases, fixed frequency reporting on hybrid architectures (P‑core / E‑core).
📊 Monitoring & Real‑World Use Cases
CPU‑Z isn’t just a static information tool — its benchmark tab (added in recent versions) provides a quick single‑thread and multi‑thread performance comparison against reference scores. The validation feature lets you upload your CPU specs to the official CPU‑Z database, generating a unique URL that proves your clock speeds and voltages — essential for overclocking forums and hardware auctions. IT technicians use the SPD tab to verify mismatched memory modules, while PC builders rely on the motherboard and chipset identification to find correct drivers.
✅ Why choose CPU‑Z over other profilers?
Unlike HWInfo or AIDA64, CPU‑Z focuses on delivering the most accurate CPU, memory and motherboard information in an ultra‑light, zero‑configuration interface. It’s completely free, updated monthly, and the validation system is the de facto standard for competition records (HWBOT, OCCT). With over 500 million downloads since 1999, it remains the first tool opened when diagnosing an unknown system.
💻 System Requirements & Compatibility
| Operating Systems | Windows 11, Windows 10, Windows 8/8.1, Windows 7, Windows Vista, Windows XP, Windows 2000, and even Windows 95/98/ME (legacy versions). Native x86/x64 support; Android version available on Google Play. |
|---|---|
| Supported Processors | All Intel (Core, Pentium, Celeron, Xeon), AMD (Ryzen, EPYC, Threadripper, Athlon, Duron), VIA, and older Cyrix / Rise CPUs. |
| Disk & Memory | ~3 MB executable, runs with <15 MB RAM. No installation required for standalone ZIP package. |
🔒 Reliability & Trust
CPU‑Z is digitally signed by CPUID, contains no malware or adware, and is used by major hardware review sites (AnandTech, Tom’s Hardware, Guru3D) and YouTube creators (Linus Tech Tips, Gamers Nexus, JayzTwoCents). The validation database stores over 200 million verified submissions, making it the largest public repository of CPU and memory configurations. Whether you are a system builder checking newly installed RAM, an overclocker pushing for a world record, or a technician diagnosing a faulty motherboard — CPU‑Z delivers accurate, tamper‑proof data instantly.
