AMD Phenom II 920 & 940 Full Review [UPDATED with more tests]

[Dante80]

Either way I will wait for more professional/in-depth reviews.

In what way do you think this review is not professional enough? The guys are busting their balls even on New Years eve to give us leechers numbers to crunch...



O_o...what a powerhog this 780!...

[roofsniper]

well it would be nice if there are more reviews just so you can confirm things and things will be different in different reviews. as you can see there on idle alone the 780a uses 40W more and that will expand out with load. you can't look at the power consumption on this review alone and will need more reviews with different configurations.

[Dante80]

Of course it would be nice to have more reviews. The more, the better.

And you are right about platform power consumption, the more different setups we have, the better (p45 instead of only X48, 790fx and gx numbers, etc etc).

Also, different platforms may give different results. For example, you may get better numbers at stock for phII if you tweak your system more (this comparison is made on an un-tweaked vista os), put better memory in, oc only the nb etc etc. Same goes of course for all the intel setups too.

From an complete power consumption I'd expect detailed system setup descriptions including used voltage meter, tools used to generate load, software running in background (if), ambient temps, idle and load temps, all bios settings whom affect load, all important voltages used, maybe even an efficiency diagramm of the psu used. Did I miss something?
Really appreciate their hard work, but these infos are required for comparisons.

For the power consumption tests the mobo i used is M3A79-T so,forget about 780a

For the 3D tests, Crysis

CPU load,Cinebench/orthos

wait so which benchmarks used the 79T? cause in the system specifications page it only says foxconn destroyer.

Thats interesting cause it's my current mobo (with Ph 9850), and I've noted that if a set vcore to Auto (or manually to 1.30v, 9850 default vcore), this mobo overvolts it in load to 1.344v. I've measured power consumption in these circumstances, and means ~12w more comparing it with a real 1.30v, exactly 1.296v (manually to 1.265v), or ~10w more with 1.31v (manually to 1.275v).
Have you checked if overvolts PhII too?
What about Intel rigs?

Interesting, first time i heared that mobos/cpu overvolt under load, usually they have a drop.

that's what happening with my Intel rig (P5B + Q6600). For example, I set vcore to Auto, and under load, undervolts to 1.25-1.26v (vcore default is 1.30v). If I set it manually to 1.30v, undervolts ~1.26v too... etc

But on the other hand, with ASUS AMD mobos occur the contrary usually, overvolts CPU like is the case with this M3A79.

These issues are crucial to keep in mind specially when power consumption tests are done, to obtain accurate results.

On asus when you see at cpu-z that on load it overvolts about 0.022v or so, its actual no overvolt and no vdroop.

I ve measured that on 4 asus(commando,maximus formula,Evolution,m3a79-t) with a DMM.
