GPU-Z is a free Windows utility from TechPowerUp for information, diagnostics and monitoring related to a video card and GPU. On supported graphics cards, monitoring can include clock speeds, voltages, temperatures, video memory usage and ASIC quality. Its Advanced tab displays support for Vulkan, DirectX Raytracing, DirectML and OpenGL APIs. When Resizable BAR is enabled, GPU-Z can report the exact BAR size. The download page lists version 2.66.0, dated May 29, 2025, and offers both a standard download and an ASUS ROG themed version. MD5, SHA1 and SHA256 checksums are listed for the standard download. TechPowerUp is the publisher; it says it began in May 2004 as an enthusiast hobby. GPU-Z is listed for Windows, with a free plan priced at no cost. Its focus is graphics-subsystem information and monitoring, rather than a broader system-management role.
