i am more impressed with the athlon 64 every day.

Like the Centrino ?

I have the dynamic clocking "Quiet N Cool" technology enabled on my Asus K8V motherboard and with AMD's latest Athlon64 driver.

This is the first desktop chip that I've had (or that I've seen that does this) automatically during normal usage.

It boots up at 800MHz (200x4) and I think 1.2v. It is cool as hell at the speed and still plenty fast for desktop use. Also at this speed, the fan on my Zalman CNPS7000-AlCu stops completely. No noise there.

As the workload increases, you can see it increase to 1800MHz (200x9). The voltage also increases. And it will fluctuate depending on the workload.

Then when the system goes commando and asks for maximum power, it goes to the default 2GHz (200x10). So, I'll be browsing the web at 800MHz, drop back to the desktop and launch NBA Live 2004 and the CPU goes from 800MHz straight to 2GHz in a flash.

I've sat back and watched this all unfold before my eyes with CPU-Z as you can see the CPU clock, multiplier, and voltage all change in real time.


AMD rocks

WOOHOOOO! I'm suprised they haven't used this as a major marketing tool.

Yeah, they should market this feature more. I think that Xbit's review was the only one that really talked in great detail about this awesome feature.

Exactly.

Does the Centrino do it dynamically based on processor load, or only off/on based upon if it's plugged into an AC outlet?

Umm, that's what Intel has had for years. Only two speeds. One for battery power and one for A/C power. Nothing as advanced as AMD's "Quiet n Cool" technology and nothing at all for the desktop side of things.

From Intel's data sheet on the Pentium M processor:


Page 14:

"this technology enables the processor to switch between multiple frequency and voltage points instead of two"

Page 23 has the various frequency and voltage levels. http://www.intel.com/design/mobile/datashts/25261202.pdf
