GPU-Z is a fine little Windows utility that, much like its CPU-Z brethren, can tell you all sorts of useful information about your graphics sub-system. The lightweight program does not require a restart, and weighs in at 922 KB. GPU-Z is distributed by TechPowerUp, and is now officially on it’s 0.5.5 version.

The new version adds support for a slew of AMD and Nvidia graphics cards, improved support for BIOS identification, and a new tab for a giveaway by graphics card vendor PowerColor. On the AMD front, the new version adds support for the companies line of A-Series APU graphics cores, AMD’s mobile cayman GPU “Blackcomb,” and various FirePro cards including the V8000, V3700, and 2460 (FireMV). On the Nvidia side of things, the new version adds support for the GeForce GT 530, GT 545, GT 560 Ti OEM, Quadro 400, Quadro 4000M, and Quadro 5000. Further, GPU-Z updated support for mobile versions of Nvidia cards, including the GeForce GT 305M, 410M, 520M, 520MX, 555M, and the GTX 580M.

The program further improves the BIOS readings of Nvidia cards as well as fixing a shader count detection bug on the Blackcomb mobile Cayman AMD parts. The ASUS MARS II GPU also receives support in version 0.5.5. PowerColor is holding a giveaway for a 6990 graphics card to a lucky winner. The new GPU-Z tab has all the relevant information as well as an entry form. Lastly, the program will now remember the last selected GPU selected from the drop down on multi-GPU systems.

The updated support is nice, and the lightweight program starts up just as fast as the previous versions. Do you use GPU-Z?  You can download the new version here.
