Question for Nvidia users regarding power management

[hideki]

Been a while since Ive owned an Nvidia card, I was wondering about the power management capabilities of the recent generations of cards.

ATI cards (since the 3000 series) have Power Play, which downclocks the GPU/memory dynamically, depending if the card is idle, mild use or heavy use. The idea being to reduce the cooling requirement and power consumption.

As far as Ive been able to find out, the Nvidia equivalent is Powermizer.

Does anyone have experience with it, how it compares to power play and what cards support it?

This is like the Cool n Quiet tech for the AMD CPU's then.

I wouldn't bother.

Too much hassle!

Power management is automatic with my 460.

Same for my 470. At the end of the day, it saves a bit of power. Hence im using it on my CPU and GPU and keeps everything cool

 

[rolypolyman]

My 470 at idle= gpu 50.6mhz
Mem 67.5mhz
Shaders 101mhz
Temp 30c
Fan 1124rpm (1850max)
Volts 0.8750v


All this from Gpu-z sensors. Oh and as stated above this is automatic.

From the responses, at least the 400 series (and im guessing later) has this feature.

Intel CPUs do a similar thing, they can reduce the multiplier on idle. It works well enough.

Its like when I have cool and quiet enabled from the bios, it throttles my speed and I can tell it is on. I do a lot of graphic design work and when Cool n Quiet is enabled Photoshop CS5 is very laggy, but when disabled, it runs very fast.

Reason I don't bother with it.

Throttles your performance!

How does it throttle your performance? It automatically adjusts its speed depending on the demand for it. In terms of GPU, as soon as you launch the game, then it will put clocks to normal. A bit like ATI and their 2d/3D clocks.
