[Behardware] GPU power consumption - 93 cards tested - Page 3

post #21 of 27
Maybe it is time for me to get a new video card. The results are interesting to say the least.

From your card you could get a GTX 470 and still consume less

It is interesting how idle power draw on high end cards dropped from about 40-50W so 20-25W

*EDIT: How about this for detail? Xbit's power consumption tests follow a similar methodology, but they also post intantaneous power draw (not only average):

Gosh looking at that makes me dislike my GTX480! Until I load up BFBC2:V .

Awesome info. If you're a 6950/6970 owner, take note of the last paragraph in the conclusion. Upping the PowerTune limits increases performance and power consumption by quite a lot.

This is really cool stuff. Loving the power consumption of the 68xx barts cards.

Why does the 4850 1GB use so much less power than the 4850 512MB, or even the 4830. More efficient pcb design perhaps?

Ah, I love my 6850's. Best little cards on the market right now, and pack a hell of a punch.

The 4830 is from harvested dies and to achieve a good level of performance they are overvolted and have higher clock speeds than the 4850 (so consume a bit more). The 1GB 4850 has the same number of memory chips of twice the density - they should consume about the same, but probably the higher density memory chips are more frugal.

They are the best FPS/W cards right now
