Could anyone tell me what the idle power consumption of a AMD64 3500+ is? TDP is also 65W (like the E2160)
As these CPUs support Cool'n'Quiet, I suppose/hope it will be low as well.

(my current system uses this CPU, and the motherboard has 8 SATA ports. See where I'm going?

)

MOD, finally found this:

Quote:

November 2004 saw AMD move into the 90 nm age, nine months after Intel did. AMD unveiled a new and very impressive CPU, codenamed Winchester http://en.wikipedia.org/wiki/Winchester (D0), which was only available in the low-cost market segment. As such, the core made its way into the Athlon http://en.wikipedia.org/wiki/Athlon 64 3000+, 3200+ and 3500+ models. The technology it was based on was anything but low-cost, though: we would have loved to see the looks on the faces of Intel's engineers when they measured the power consumption of AMD's 90nm CPUs and realized that even under full load, this unimposing CPU draws a mere 31.4 W. This means AMD was able to reduce the power consumption by about 44% clock for clock. Further measurements taken on a specially-modified motherboard in our Munich lab showed an idle power consumption of only 11.1 W.

But the best was yet to come. When the Cool & Quiet feature was activated and the frequency dropped to 800 MHz, the CPU contented itself with incredible 3.2 W. The Winchester was followed by the Venice stepping, which added SSE3 support to the Athlon 64 and lowered the power consumption even further.

I have a Venice core. Are these numbers correct? Because they are pretty sweet

As I still have a XP120 CPU cooler lying around, passive cooling would be no problem

About right I think.

I remember having 3200+ C&Q enabled and when browsing the fan just turned a few second severy 5 minutes... And even then it turned very gently.

Could someone tell me how much energy an AMD Duron 800-1000Mhz CPU consumes when idle?

piotke · 1st July 2008, 09:56

I'll measure it this evening. Have a durun 700 here.

BlackRabbit · 2nd July 2008, 12:46

Thanks!
Information of that kind is not easy to find, unfortunately

Those days we didn't mind power consumption that much, I suppose

Can you measure CPU power consumption? Or will it be the total system (cpu,mobo,ram)?

jmke · 2nd July 2008, 12:48

total of course, unless he's able to solder some resistant directly to the CPU socket to measure power draw

anyway, difference between 10W and 30W is not huge BR, let's not get carried away here!

It's not really the electricity costs that make me ponder. The machine is installed in a pretty small place, without any ventilation. In these circumstances, 20W of power can make a lot of difference in roomtemp.

However, (re)discovered athcool (for AMD Athlon/Duron CPUs). Seems to be able to lower CPU temp reasonably (and thus: room/system temp).

Piotke: could you perhaps measure the difference with<->without athcool-like tools? (unless ofcourse, you're not actually booting into some OS). It would be interesting to see how much difference such a tool could actually make

Will test, but after werchter.
