Measure ‘Quality’ with GPU-Z 0.5.8

GPU-Z is a handy tool for looking up information on your graphics card, verify your overclocking efforts or even export the BIOS (in those rare cases when it isn’t locked, particularly in a laptop).

The latest version brings some additional features to the table, including support for the latest (sort of) mobile GPUs from Nvidia (GeForce GT 640M) and AMD (Radeon HD 7690M).

Another practical feature is a simple render test that puts the card under load, which makes it easier to identify capabilities that might be ‘hidden’ due to power saving measures–in this case with a particular focus on the PCI-e bus configuration.

One of the most interesting additions, however, is an ability to display ‘ASIC quality’ for Nvidia Fermi and AMD Southern Islands (i.e. only Nvidia support for laptops for now, since there are no mobile Southern Island chips yet).

This quality score, displayed as a percentage, supposedly indicates how the manufacturers have sorted the GPUs according to electrical leakages. The developers have allegedly “found ways in which ASIC quality can be quantified and displayed.”

You access the feature by clicking once on the PCB icon in the title bar. This GTX 580M’s ASIC quality is apparently 73.7%, but for some people the number seems to exceed 100%, so there are definitely some good reasons to take these figures with a pinch of salt. In this case, the GPU works perfectly in spite of its paltry ASIC quality score, even at slightly-above-standard clocks.

All new features in GPU-Z 0.5.8:

  • Added explanation about PCI-Express power savings and 3D render test to accurately measure bus config under load
  • Added function to display ASIC quality for Fermi and Southern Islands. (Located in the GPU-Z system menu; click the icon in the top left of the window)
  • Fixed crash on older ATI cards
  • Added voltage monitoring for HD 7970
  • Improved real-time clock monitoring for HD 7970
  • Fixed OpenCL detection for AMD Antilles, Whistler, Seymour, Blackcomb
  • Improved default clock reading for AMD HD 7970 and Fusion
  • Added support for AMD FirePro V7900, HD 6930, HD 7690M, HD 6410D
  • Fixed Intel Sandy Bridge IGP to be DirectX 10.1, 32 nm
  • Added support for NVIDIA Tesla C2075, GeForce GT 630M
