TechPowerUp GPU-Z 0.5.8 Released

TechPowerUp today released the latest version of GPU-Z, our popular video subsystem information and diagnostic utility that provides you with accurate information about the graphics hardware installed, and lets you monitor their clock speeds, fan speeds, voltages, VRAM consumption, etc., in real-time. Version 0.5.8 introduces two new features. The first one is a render test that applies sufficient load (not stress) on the GPU to pull it out of PCI-Express link-state power-management, to ensure the Bus information is accurate. If you find the PCI-Express bus link speed or PCIe version displayed incorrectly, simply click on the "?" button next to the field to launch the load test.

The next new feature is ASIC quality, designed for NVIDIA Fermi (GF10x and GF11x GPUs) and AMD Southern Islands (HD 7800 series and above), aimed at advanced users, hardware manufacturers, and the likes. We've found the ways in which AMD and NVIDIA segregate their freshly-made GPU ASICs based on the electrical leakages the chips produce (to increase yield by allotting them in different SKUs and performance bins), and we've found ways in which ASIC quality can be quantified and displayed. Find this feature in the context menu of GPU-Z. We're working on implementing this feature on older AMD Radeon GPUs.

The full change-log follows.

  • 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)
  • 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

did you try GTX 460 768MB bios? your ASIC quality is rather high maybe you'll have 336CC..

dontknow what u mean all stock bought the card new like this mean i got a bad card?

Higher = better, yes?

ASIC quality value seems to follow very well the VID of cards. Lower VID, higher ASIC quality.

Gigabyte GTX 460 SOC 1GB with VID of 0.962V and stable at 915MHz core at default voltage.

so is this the chips binned across the entire gpu series because i tried a 4 cards

GTX460 768 40%
GTX460 41.1%
GTX470 59.5%
GTX580 98.2%
My GTX 460 1GB is


need to see more GTX 460 results see if this is normal i run my card ar 800/1000/1600 all the time hangs around 55c max temp

I think Afterburner shows possible VIDs for many different GPUs. For example my old 6950 TFIII showed 1.10 and 1.15 VID choices, and it was a 1.10V card, meaning higher leakage.

A high leakage card operates at lower voltage to balance the otherwise higher power draw and temps. It will also overclock higher than what a low leakage card would. The problem is though, cards usually have a limit of voltage increase, say +150mV for 6950, which means AB could overvolt a 1.15V card to 1.3V, but a 1.1V card would crash above 1.25V.

A high leakage card is what you want if you do extreme OC, and you can keep the card cool (H20,LN2 etc.). Your mileage will vary of course, not all low VID cards are good OC cards, and not all high VID cards OC bad. It's a part of product binning, they try to fit in as many chips as possible to a similar spec.

My rating

I have GTX 580's in SLI. The rating is 86.5%, is that for both cards? Does GPU-Z average both scores?

Is that a good score? I have no idea what it means.
