GPU-Z Overview
GPU-Z is a free, lightweight graphics-card information utility for Windows from TechPowerUp that reports detailed specifications and live sensor data for your GPU. It shows the graphics processor, its clocks, memory type and size, driver version, supported technologies, and a real-time sensor view of clock speeds, temperatures, fan speed, and power draw — useful for monitoring during gaming or stress tests. A notable feature is its ability to verify that a card is genuine and flag certain fakes, which makes it popular for checking second-hand GPUs. It can save a copy of the graphics card's BIOS and log advanced sensor data for troubleshooting, and it works across NVIDIA, AMD, and Intel graphics, which makes it a standard tool for both diagnostics and confirming a card's identity before purchase.
