[Grooveriding]

What experience is that exactly Grooveriding?

Are you saying your 480's now throttle in furmark?

Prime95 isn't that bad, an unfair comparison actually. Test with AVX Linpack, overclocked with your chip at 5GHz let's see how "realistic" that test is.

I've owned AMD cards, most recently 5870s, they didn't throttle in Furmark.

Prime95 is a perfectly fine comparison, it loads your CPU pretty hard with small FFTs. It even caused throttling on my current machine, before I installed a block on my MB, because the VRMs on my mobo got too hot.

Not sure why you have such a hard-on against Furmark ? Because nvidia doesn't like it, or what ? It's a good program to make sure your overclock is stable. You can even remove the driver throttle from nvidia's driver via a hack if you like. They just don't like how much it highlights power consumption and temperatures. It's certainly not a 'virus'.

This can't be true, reviewers won't have enough leeway to get reviews up when the NDA is lifted.

And who said that this guy is a reviewer? :hmm:

Because AMD and Nvidia block it?

Just because you are unaware of something doesn't mean it's not true.

You realize you can tell if it is throttling right, clock speeds get reduced in Furmark.

Do you have a link to back up that AMD throttles Furmark ? And why is it such an issue to throw AMD in with nvidia as throttling Furmark, anyways ?

Good grief, man. Not everything is AMD vs nvidia.

Grooveriding you've been spending too much time looking for flaws in your own hardware, AMD has been throttling furmark since before 4xxx series and powertune is a power throttling "feature".

It's not about Nvidia vs AMD, in fact I can't even see how you came to that conclusion, it's about Furmark being a worthless program to rate video card power consumption.

 

[notty22]

According to these articles AMD throttled in software looking for furmark.exe at various times. Then they added a VRM monitoring circuit that throttles when programs like Furmark are run, based on VRM heat, because they exceed any normal gaming/programs. Of course o/c , changes that and throttling can happen in those cases to.

Furmark will still have a purpose. When you want to disable throttling and see exactly how much juice your gpu can suck up.

And speaking of juice, nothing beats the 480! (except the marsII and other exotics)

I bet groove could pull 1000 watts with his 3, throttling disabled

Here's the answer.

Yes, Furmark is throttled on AMD cards just like it is with nvidia cards. However, it is only throttled when powertune is at 0%. All review sites push powertune to 20% to test TDP and powertune > 0% will result in furmark not being throttled. This is easy to see yourself by using Afterburner, with powertune at 0% the clocks will not ramp up. But anything higher than 0%, it will not throttle and clocks will be 100%.

Someone remind me why this is being argued? Just curious. You can also disable furmark throttling on nvidia cards, but you cannot do so through the driver. You have to use GPU-Z with the command line argument -GTX580OCP (If I remember right).

That reads as hardware vrm protection on the 5870, not driver throttles. My 5870s did not throttle, also power time if I recall was added on 6xxx and is user controlled.

Whatever the case, there is nothing wrong with furmark if you have a stable system was my point. I guess that could not be said though with the possibility of impinging on the faith.

 

[notty22]

It's just more consistent to compare power pull comparing various cards using a couple games. Not just furmark.
It's good thing there is throttling mechanisms for VRM / tdp as long as normal overclocking is not effected. And I'm sure extreme o/c's want a way to over-ride that as well.

Because people want to use it's abnormal power draw as an indication of actual power draw. When some companies were throttling others were not...

I didn't bother to scroll up and read the rest of the posts related to this, but AFAIK most reviewers test with powertune at 20% (which is not normally what is used) - and it is not throttled at that setting.

I'll just close by saying...Who gives a F about furmark throttling :thumbsup: not this guy

It's being argued because of the nvidiots have nothing else to throw at AMD. Let's get the thread back on track.

Good results, but the thing that struck out to me is they only got 1150MHz on the GPU? Not much of an overclock.

I think I'm going to take the advice I received in an awesome PM from a friendly user and just drop the gpu section from my bookmark page entirely.

It's such a round number that I think it's software limited. Hardware limits will vary from sample to sample, of course.

Shocking, dual 7970s uses as much power as a 7970 times two. Maybe less in fact.

Whoa.

Thanks for posting this :thumbsup:

 

[f1sherman]

yeah I know, but did you see those 270W?

not so eco friendly - cool'n'quitet when you switch to +20% is it?

it even races ahead of gtx 470 D:

You're running out of rocks to throw at AMD. C'mon, you can do better than this :thumbsup: (still don't care personally, cya.)
