Quad core power consumption

[mishima]

Just wondering, compared to the core 2 duo - what does the quad core chip consume in watts? Does it demand more power from the PSU?

I just looked on Intel's web site. A Q6600 is rated at 95W TDP. An E6600 is rated at 65 W TDP.

So nothing drastic then in comparison! Cool thanks

Arn't the E6600 the old stepping versions? I would imagin the E5500 would be half of 95w as its like a Go 6600 isn't it? Seems only logical that a quad core use twice as much watts for the same clock speed as a dual core.

Read their mechanical and thermal design whitepapers and find out.

Hows the phenom compare generally

Sounds like a lot of effort to me.

The 9.xx are about 90W, and the FX 8.x are 125W.

That does sound quite a lot but if they can switch off the cores when not needed, it should run a lot cooler. It'd be nice to have the HSF on 600rpm when the machine is just idling, I do that now with my conroe but it goes to 70c

If you overclock with your C2D Dual or Quad its worth trying C1E - Enhanced Halt State and EIST this will automatically drop the cpu's multi and volts to the lowest default values when idle, when put under a sufficient load the multi and vcore increase to deal with the load and drop back down when idle.

Edit:
The vcore aspect of this may not work with overclocks that require a lot of volts. It may take some experimentation on your part.

I use the multi drop and thats fine. The voltage drop would make it unstable I think, Im not sure it works with overclocking?
Is that what you use with yours, I have the same board and cpu.


I just checked and eist and c1e was allready on

Without auto voltage on vid the above is disabled. Obviously it wont boot to 3.4ghz unless I set the cpu voltage manually and even turning +100mv to auto resets it on windows load. No go :/

the original quad core tdps where 130w i think (as in the b2 core 2 extremes, not the b3s), the reason the b3 has a tdp of 105w and the g0 has a tdp of 95w is probably because of newer steppings etc.

Your right enough this is why I never actually seen the voltage drop at any time. It does needs vcore to be on auto and like you say it maynot supply enough volts to be stable at a high overclock.
