How to Check Your Computer Specs on Windows and Mac

Knowing your computer’s exact specifications helps you troubleshoot problems, determine upgrade options, check game compatibility, and make informed buying decisions. Here’s how to find every spec that matters on Windows and Mac.

Windows: Quick Overview

The fastest way to see basic specs:

1. Press Win + I to open Settings
2. Go to System → About
3. You’ll see: processor (CPU), installed RAM, system type (64-bit), Windows edition and version

Windows: Detailed Specs

CPU (Processor)

• Settings → System → About shows the model (e.g., “Intel Core i7-12700K” or “AMD Ryzen 5 7600X”)
• Task Manager (Ctrl+Shift+Esc) → Performance tab shows real-time speed, cores, threads, and cache

RAM (Memory)

• Settings → About shows total installed RAM
• Task Manager → Performance → Memory shows used/available, speed (MHz), form factor, and how many slots are used
• Command Prompt: wmic memorychip get capacity, speed, manufacturer for per-stick details

Graphics Card (GPU)

• Task Manager → Performance → GPU shows model, VRAM, driver version, and real-time usage
• Or: right-click desktop → Display settings → Advanced display → Display adapter properties
• For NVIDIA: open NVIDIA Control Panel → System Information

Storage Drives

• Settings → System → Storage shows drive sizes and usage
• Device Manager → Disk drives shows exact model numbers
• Task Manager → Performance → Disk shows type (SSD vs HDD), read/write speeds
• For health: download CrystalDiskInfo (free) — shows SMART data, temperature, and total writes

Motherboard

• Command Prompt: wmic baseboard get product,manufacturer,version
• Or download CPU-Z (free) for detailed motherboard, BIOS, and chipset information

Everything at Once

For a complete report: open Command Prompt and run systeminfo. This dumps CPU, RAM, OS version, network adapters, BIOS version, and more.

For a hardware-focused deep dive, download HWiNFO64 (free). It shows every sensor, every spec, every detail about every component.

Mac: Quick Overview

1. Click the Apple menu → About This Mac
2. Shows: chip (M1, M2, Intel), RAM, macOS version, serial number
3. Click More Info for storage, display, and additional details

Mac: Detailed Specs

• System Report (About This Mac → System Report) shows every hardware component, serial numbers, firmware versions, and connected devices
• Activity Monitor (Applications → Utilities) shows real-time CPU, RAM, GPU, disk, and network usage
• Terminal: system_profiler SPHardwareDataType for hardware summary
• Storage: Apple menu → About This Mac → Storage → Manage

Why Specs Matter

• Upgrading RAM — Need to know current speed, type (DDR4 vs DDR5), and available slots
• Game compatibility — Compare your GPU and CPU against minimum/recommended requirements
• Troubleshooting — When getting remote support, having exact specs speeds up diagnosis
• Resale value — Accurate specs help you price a used computer correctly
• Storage upgrade — Need to know if your laptop supports NVMe, SATA, or only eMMC
