Typo at 2nd table table model 620 works at 2.6 GHz not 2.8 GHz.

Otherwise nice article

Page 4: charts read "Regor" where they should read "Propus".
Still reading the rest. Seems to be well thought out and well written with a few typos here and there.

It's all good though. You're only human.

Hi, nice review!
I consider that the power consumption data is a bit wrong.
If I understand correctly the motherboard used for the amd tests has a chipset with integrated video. Using this kind of motherboard the power would be higher. And if you keep in mind that this is the most powerful integrated video it is possible that about 20W to be consumed by the video part of the chipset.
I saw a similar review on AnandTech and the power consumption reported by them for the intel cpu's is almost the same as yours but the amd values are at 175/179 for the 620/630.

All credit for AMD for this not expensive quad.I respect Intel too but problem of today Intel CPU is too many socket.

Except that AT do not show you the CPU consumtion. Xbitlabs is the only review site, to the best of my knowledge, that does it. If you want to eliminate the effect of the chipset power consumption look at the pure CPU numbers.
Xbitlabs, two tumbs up for showing the CPU power consumption!

AMD CPUs include IMC and so the CPU power consumption figures are not apples to apples.

I am not a MB expert but, the Xbit "pure cpu" is the additional 12v line to the Motherboard. I do not know for sure but is it possible that other components on the MB use power from that line?
I appreciate XBit reviews for the amount of detail that they bring and I praise some of the authors especially Anton Shilov.
But this time something is fishy.

No, the 12V CPU connector is exclusively for the CPU VRMs.
There is only a problem with Intel's new i5/i7 CPUs as these are not only drawing power from that CPU power line, but also from the normal 3,3 ATX line.

Hi,

nice article, I liked it.

Just one question concerning the overclocking results: Did you try to lower the NB multiplier ?

I guess the problem with the bad OC results is the NB clock. It normally maxes out around 2,6 - 2,8 GHz with Denebs, depending on the NB voltage.

I understand that there are no Black Edition Propus, however I assume that lower NB multipliers should be supported. Please try it out, if you have time.

Thx

Bingle

I tried to lower NB multiplier. But it didn't have any impact on OC results. BTW, Athlon II have no L3 cache that is why they can run with higher NB frequency than Phenom II CPUs.

Hi,
I try to figure out the power consumption of a phenom II 925 CPU, but I am a little bit confused.
I have found an earlier article about the phenom II 920 CPU. As I know, the phenom II 920 has 125W TDP, while the 925 CPU has 95W.
The earlier article said, that the power consumption of a system with the 920 CPU under heavy load is 219W. This article says, that the power consumption of a system (which is almost identical to the earlier one) with phenom 925 CPU is 239W.
I think there is a problem with the testing methodology ...
The earlier article is here: http://www.xbitlabs.com/a...-920-overclocking_12.html
