Power consumption of 3D cards?

[walkingdog]

I visited several websites and accomplished the following chart.


Every hardware website has its own way of measuring the power consumption of 3D cards,
some websites give the details on how they get the “numbers”.
Normally, 2D power consumption is measured while idling at desktop,no running programs at all.
Under 3D, however, this gets a little complicated
when every website uses different testing methods.
For instance, some use 3dmark, some use furmark, and some use crysis,
even MSI Kombustor is favored.
This results in a big difference –
websites using Kombustor show gts450 consumes less power than 5750,
But websites using crysis or furmark show gts450 is more power hungry than 5750,
I think under 3D 5750 is more power saving than gts450, still I have my doubts -
First,
Of what website do you think the most accurate while comparing to real 3D gaming conditions?
Crysis? Heavily 3D stress reflects the real gaming conditions?
Give your point to support your favored website.
Second,
TPU uses a unique way to get their numbers. They don’t test the whole system,
but via PCI-Express power connector(s) and PCI-Express bus slot to gain the number,
I think their “average 3D” is good although 3dmark03 is an antique,
but for me “average number” is more convincing than peak readings.
I give my vote to TPU, what is your point?

You've missed completely XBit Labs. :)
IMO the best methodology ATM.

I didn't miss it,
but until now no gts450 review on xbit, right?

Yep. Will follow, I'm pretty sure. :)

I have to ask.
As a power user, why do you give a rats about power consumption?
Is it because the cards are all almost equal in performance that they have to find another unit of measurement to pick on and differentiate between?
I don't know a single gamer that doesn't have a laptop, and then a gaming machine and shuts off the gaming machine when they are done, other than myself. I just leave mine on all the time and assume 1000w in my PSU means I will be pulling that if not less from the wall at any given time.

I dunno give me a chip that runs well, lower the heat output as much as possible and make it perform. I'm happy. Guess I'm special! Hahahah

[_dangtx_]

well, it's important for those that care about the monthly bill, or maybe the heat output, or noise, or all of the mentioned plus some.

And here it is.
