The Truth About Graphics Power Requirements V2

Recommended Posts

That's totally understandable.

The csv or/and website is a pretty cool idea too.

 

I'm looking forward for any new development (whenever it happens).

 

Thanks again for the reply and for your hard work. :)

Yeah I saw that and is mainly the reason I didn't use that review as a source (can only have 4 source results per card atm) and as I had 4 other reviews to choose from I used those instead. All the other sites that measure accurately were reading about 20W idle.

 

I often filter out obvious variations like this. If a result skews too far from the standard deviation I omit the offending reading. Or use another site's results. If there's not much data around I may stick with it even if it skews a bit much, as I think with not much data, any more data even if not quite correct still helps.

 

In this case 10W and 33W is quite varied compared to what 4 other good sites were measuring, so left xbits out this round.

fair enough

silly me for not looking at the reviews you had collected the data from first

would the average user ever see that kind of draw? I doubt it but never the less that is what the card draws at full tilt maybe add a second GTX580 uninhibited column or something?

I'd was going to suggest leaving it below the Furmark level, however after a bit of a look around I did find this:

 

While this is a hardware measure the real trigger is in software. FurMark and OCCT are indeed throttled, but we’ve been able to throw other programs at the GTX 580 that cause a similar power draw. - Anandtech GTX 580 Review

 

To be honest I wasn't aware of anything else that put up that kind of sustained draw, so it is a bit of a surprise. To be honest I'd leave it at 300w for a little while rather than worrying about it excessively right now - it'll take a while for various other RL ingame to come in (not that I doubt techpowerup et.all per se, just I think more data points would be good). If that does turn out to be anything other than a very unusual case though definitely up the peak load, however at a guess I'm thinking that won't be necessary.

Sorry about the long wait between updates.

I hope you may update soon with these newer cards in the wild (mostly GTX 560Ti), and thanks for your efforts!

Yep, with the imminent release of the GTX550 and dual GPU cards from both camps I'll post an update once they're out.

We'll wait: the official launch of the reference Nvidia GeForce GTX 550 Ti (GF116) is scheduled in three weeks' time.

Glad you found it useful :)

 

 

 

Interesting that I haven't posted an update in a long while. Basically nothing has come out since!

 

Well there was a FirePro card out yesterday, but apart from that not much. I'll probably wait until HD7000 series before the next update.

Holy mother of God. After all this time I'd not looked at this. Amazing work Mark, after reading the methodology this has to be the best resource I've seen for this topic on the interwebs!

 

You sir is a winrar!

The charts are no longer visible on the site, and no information is presented in text. I just thought you should know...

Yeah it's bound to happen, websites get updated, URLs change etc. I'm not going to bother updating links once I've put them in. At the time I put them in they work.

No doubt though you can search their site and find the article in question though.

rofl you've only just seen this? This has been going since well before forums 3.0 launched. :P

In fact this thread really should be called V3 not V2. Had to do a lot of rejigging when forums 3.0 happened (back then all graphs we're ASCII art!)

 

But yeah, glad it's useful and thanks for the praise. Like watching the thread views go up. No one comments much but I know it gets looked at a lot lol.

Okay, so my PSU supplies 408W on the 12V. My CPU's max TDP is 128 W. Therefore, that leaves ~280W for the GPU right? The AMD 6950 uses 176W @ Peak 3D. Does that mean my 450W XFX PSU can handle a 6950?
