Real Power Consumption - 4870 X2 & GTX295 out of Spec!

Since we're at it, why not badmouth all the people who drive sportscars?

Already done that (Unless its a Tesla I guess!)

No, I would say pure electric cars. Hybrid cars and cars like the volt is just a joke. There is a plan here in Denmark to have 100000(From TV news) pure electric cars running in 2011 together with an american organization and the biggest power company here. I´m not sure how many cars there are here. Something around 1 or 1½million.

The key would be standardlized batteries. Cars will have a 160km(100miles) range on a charge. And charging stations would simply swap battery. Its faster than putting fuel on your car today. You can ofcourse also charge it at home.

And how is the electricity generated.

Will the current installed electrical grid supply the demand?

That's the big issue right now. A bunch of all-electric cars would put an enormous strain on the power grid.

Just wait, electricity will be rendered from...

hahaha that pretty much explains it all.. stuff like this gets ridiculous...

Mainly windmills at night. And then there is hydropower from norway aswell at night. Both are "uncontrolled" and thereby having large excess capacities at night and with windmills also when its very windy.

Its calculated that 700 windmills can keep the entire danish carpark running on electricity. Even making gas into electricity is a large plant would be more efficient that out in the car

But again, we also burn biofuel for CO2 neutrality. So its a win/win.

I'm sorry but the electric/hybrid car market is a big joke. Mainly because the arabs won't let an actual substitute for gas on the market, because that means less money for them. This may sound very childish and/or unlikely but you just have to look at the amount of good ideas for "clean" energy that get thrown in the bin for unclear reasons.

Look at what we have now. electric cheapo cars that won't even do 100mph and that will run out of battery charge in less than 100miles. Or that failure of the hybrid prius, which gets its ass spanked by the newer 1.3/1.4l diesels in terms of mpg and performance. The market REALLY does want you to overlook the green cars as of now.

Back on topic, I'm sure the cards weren't designed to run a very heavy stress test. If you game/render/work on them and they overheat, then that's another matter. AND if they draw double than what they're advertised to draw, then you have the right to complain. I mean, just look at how big the stock gfx cooling solutions are getting.. Soon we'll need a case with its own airflow just for the card itself. The problem is that both NV and AMD will not back down on their specs/anything, since we still buy them no matter what they draw, because they're the best of their league..

1) TDP is one thing, power consumption is another
2) furmark is not representing real-world, so it's useless for drawing conclusions about the real world.
3) Anyway, I found the article usefull because it confirms what I was thinking about the power consumption of 4870X2 and GTX 295: 4870X2 is wasting more energy; it's significantly hotter, thus louder when it's on load.

The hybrid cars are the most energy efficient cars available at the market that have decent performance and can satisfy the average-joe's needs.

That plan is very ambicious. I don't beleive that it will be realised in 2011.

The key would be standardlized batteries. Cars will have a 160km(100miles) range on a charge. And charging stations would simply swap battery. Its faster than putting fuel on your car today. You can ofcourse also charge it at home.

The key is to let better technologies enter the market. There are batteries with several times larger energy capacity then the best Li-ION batteries, capapble of recharching to full capacity within 30 min.

Hey, but let's not forget that there is engine using pure water as fuel. The only reason why we are still driving cars on fossil fuels are the big boses who want to milk as much money as they can from the old and outdated tech.

And how is the electricity generated.

Mostly in the nuclear power plants.

Will the current installed electrical grid supply the demand?

I doubt, but it's a piece of cake to upgrade the power network, ofcourse if you have money.

I see that most of you don't care about power consumption, but these cards draw power way above the specs of the cables and connectors.
About using Furmark: Isn't it my decision what software I run on my GPU? If I decide to run Furmark on it, I expect that the card still operates according to the power connector specs, and that the on card power regulation can handle all the load a software can generate (according to the test, the GPU voltage regulation got really hot).
Also, if I want to use the GPU for computation - do I have to limit the load to (let's say) 80% to not burn the card/my computer?

[gOJDO]

Well when we talk about gaming performance, power consumption is irrelevant. Also, for somebody willing to spend $500 for a graphics card, the delta in the bills doesn't matter at all. And don't forget, this is XS.

but these cards draw power way above the specs of the cables and connectors.

The "specs for the connectors and the cables" are BS. The cables and the connectors of every PSU can carry significantly more current and operate at significantly higher voltage than the max the PSU can give in a worst case scenario and for a long period.
On the other side, the connectors on every graphcis card are designed to carry on much more than the needed power flow. No wonder no body has issues with the electric cable installation on an overvolted and OC-ed cards which are consuming way more energy than @stock.

About using Furmark: Isn't it my decision what software I run on my GPU?

It's also your decission if you are going to OC the card, increase voltage and work in a high ambient temperature.

If I decide to run Furmark on it, I expect that the card still operates according to the power connector specs

Again these "specs" are a crapload of BS.

, and that the on card power regulation can handle all the load a software can generate (according to the test, the GPU voltage regulation got really hot).

If there were issues, there were going to be lots of dead cards, especially 4870X2's due to thier very high operating temeperature.

Also, if I want to use the GPU for computation - do I have to limit the load to (let's say) 80% to not burn the card/my computer?

You can safely use your card @stock for whatever computing purpose you want. Heck, you can OC your card and limit it to (let's say) 120% and not burn the card/computer.

You know the companies are not paying huge sums of money to their engineers without a reason.

Yeah! Why not? Hummer stopped making H1's in 2006 because we decided that they slurped way too much gas.

Furthermore, Hummer sold 54,052 H2's in 2006 and only 6,095 H2's in 2008. A huge difference, eh?

[Serra]

Higher power consumption is one thing, but that's pretty drastically out of specification.

In fairness to the hummer, that doesn't take into consideration that the H3 exists - so it's really more like 54k vs. 27k. Still a huge difference, mind.

I'm sorry to say the biggest reason for that is that in 2008, even people with very good credit were having trouble getting car loans. Also there was the very high gas prices.

<shrug> go ahead. Corvette can get near 30mpg on the highway so I don't see a problem. Pretty impressive really.
And you badmouthing me won't stop me from driving my Camaro

The Corvette is an amazing piece of machinery and I dread the day that my only choice in cars is some impotent econobox.

Back OT- Forgive my ignorance, but isn't pulling more power than the spec allows bad for parts longevity? If the PSU has enough amps on the 12V rail, what other shortcomings might there be?
