Which values are always 100% accurate?

[Popolollo]

For example, are ROPs/TMUs always accurate? Can I use that value to spot cards with modded bios, and other types of mods?
I am getting values that make no sense to me. Like 1/1 ROP/TMU on a Radeon 8500. Even if it were a 9100 or LE, that value would not make any sense. But I know nothing. Can I trust that value, and what are the other values can I actually trust, i.e. fetched directly from the card.

Thanks!!!

It depends on the card/generation. For some really really old cards like the ones you listed the detection code is not complete

Thank you for the answer. What about memory bus width, amount of vram? I am getting a 3D Prophet II Ti as 64 bit, 32mb, but should be 128 bit 64mb, just because it doesn't seem to exist an Hercules Geforce 2 Ti with just 32mb. Thanks! A friend told me it might use high density samsung chips, or quadflat pack chips. Is that possible? How do I verify?

The Geforce 2 Ti mentioned has only 4 vram chips, like most of 2 Tis. It was released at the same time of the Geforce 3 Ti 500.
Is there any way I can help with completing the detection code? I have a bunch of old cards whose report doesn't seem accurate. I'd be willing to help improving that.

There really isn't much value in updating GPU-Z to detect ancient GPUs that only a handful of people in the world care about. I imagine that the detection code is already very convoluted and W1zz is unlikely to be interested in making it more so, which is a maintenance overhead tax for very little benefit.

Fair enough! makes total sense. However, back to the original question.... because even if it's not perfect surely something can be trusted... which are those values? Like, the frequencies? Unfortunately the amount of ram doesn't seem accurate in some cases. 4x high density samsung chips show as 32mb but they actually 64mb. Thanks!

Use good ol' Everest Home Edition for old cards, should detect them better.

For such ancient cards I don't think I can even tell you that, because I don't have any here for local testing. Everything newer than ATI R300 should show everything correctly, or it's a bug.

Try a few other sysinfo utilities and report the differences

I do! But I try to cross verify on multiple programs. There are a lot of fake cards with modded bios out there. Sometimes it's really hard to tell what's what. Thank you folks.

Thanks! With "report the differences" you mean I should submit bugs in GPU-Z with the incorrect info? I don't want to bother anyone with antique cards. As Assimilator said, it's not worth it. Thanks!

Please always report issues, so that I'm aware and can prioritize. Also for other users who might be wondering about the same
