In that article Charlie is talking about putting four Fermi Tesla's in a 2U case? But when I look at the newegg server case selection, 2U doesn't look that large.

What am I missing here?

Chicken Little thinks it's bad.

Very bad.

Putting them into a render or compute farm?

Yeah it is, a TDP of 188W for the 5870 vs a potential 275W for the Gtx 480 is a electricity bill/power consumption caveat.

I believe the boxes state it needs a 650 watt power supply. The 295 is listed as 680 watts. So I doubt it is 275 watts. Closer to 250 is my guess.

24 hours a day 7 days a week peak power will cost you 5$ more a month.
If you can afford 400$ cards, it shouldn't be a problem.

I think they're also going to have trouble doing a single card/dual GPU product due to power and heat. So, 5970 may stay at the top of the heap for a while.

Are the enclosures shown in that picture 2U?

If so, I am still having a hard time visualizing how four dual slot video cards would fit in each one of those tiny boxes?

Seriously YMMV.

Power costs 3-10x more here than a city owned electric company across the river. With a card such as that, it could mean a $40+ change in power costs.

Its really not going to be that much unless your computer is going full burn all the damn time (Ok it might be a problem for folders, but not really anyone else).

I think the power difference would be more of an issue if ATI was competing with Nvidia in the GPGPU market.

ATI doesn't sell video cards for GPGPU right? (Please let me know if I am incorrect)

Depends on where you live.

Yea, that means if your electric is 8x more then mine it would cost 40$ a month.
Now do you really game 24 hours a day ,30 days a month? NO.
So if you game 40 hours a month it would cost you 5$ even with your high electric bills.

Seriously, its only an extra light bulb. (100 watts) Big deal.

So Charlie was wrong about the 280w and admits it!

I'm sure many folks around here will feel vindicated.

If I understood what I read ,the original target was 225 watts and they raised it 50 watts to 275.
Mabe they raised the clocks to the target 750 from 625?

 

[frostedflakes]

According to the slides Charlie linked to, 225W was for a 448 SP part, in other words, the GTX 470. I don't see anything claiming the 512 SP GTX 480 was supposed to be 225W.

I was giving that reasoning for the sake of comparison/argument. Being a PC geek I like to choose the "best" based on any credible fact I can get. Lets say even if the bill is not an issue, it still may generate more heat, causing somewhat of a "warming" effect to the overall system.

Correct me if I'm wrong though.

Ok, but how much does noise figure into the equation?

P.S. I actually think it is amazing how Companies like Nvidia come up with creative methods to improve cooling (such as the backside slot on Fermi) while working within the restrictive ATX spec.

Then which one got raised 50 watts the gtx 470 or 480?
If it was the cut down part ,which I assume is the gtx 470, then they raised the gtx 470 by 50 watts and now is 275 watts? That would mean the gtx 480 is over 275 watts.

It sound to me the gtx 480 was 225 watts and was raised to 275 watts.

Quote:

If you recall, the official story is that the card, in it's cut down and underclocked version, pulls 225W. That number, along with stunningly poor performance, has lead to some notable backpedaling. If that isn't bad enough, some sources at GDC told SemiAccurate that Nvidia jacked up the TDP by 50W last week without warning.

You must stock up on candles then.

Charlie is claiming that the TDP of the GTX 480 was raised 50w. His "support" for this are some old nVidia slides claiming that a 448 SP Fermi was rated for <=225w. Considering the GTX 480 is a 512 SP part, I don't know why he's quoting the TDP of a 448 SP part as the original TDP of the GTX 480, but whatever.

Thats what I was trying to say.
Something is not right here.

If the gtx 480 "was" 225 watts and raised 50 watts to 275 watts ,then whats the gtx 470? under 200 watts? Or did they raise them both?

Are dual GPU video cards used in HPC?

At the moment, I cannot seem to find the Tesla equivalent of 295 GTX?
