Thought the 448 would be higher as that's a crippled 580 core like the 570 ;)

They can't know where in the wafer it was just through software detection though and even if they could why would GTX 570 all be the centre of the wafer and GTX580 not? :p

I think all that's happening is that the GPU-Z devs have decided on a benchmark voltage for each model (that they've presumably chosen by inspecting a range of cards) and they simply compare the VID of each GPU to that benchmark to get a percentage.

GTX 570 probably scores highly because they're effectively just downclocked GTX580's and most likely all have a similarly low voltage.

Did You really think the guy who mentioned positioning in the wafer meant it :D

It must work on some set of parameters, but I would not give it a second thought, it's just a bit of fun ;)

Hmmm, well volts don't to into a GPU, they go through it. It could be that they have a way of measuring this. Perhaps it is just making calculations from the VID. It may also be that the GPU packaging has some kind of coding too.
 
Sooooo, I think I've got a record here, 44.0% on my Asus GTX 480 I bought from OCUK.
It runs about 5/10 degrees hotter than the other in SLI.
The other 480 is a PNY GTX480 second hand and that one reports 84,9%.

Asus GTX 480: 44%
PNY GTX 480: 84,9%

how do you do this test? opened up the lastest version of GPU-Z but no asic quality? i have a 7950 so should work

ar found it! didnt read instructions!
 
PNY GTX480: 72.6%
Not that I believe this measurement has any connection with the real world from the figures seen (>100%??).
