This morning I finally received my Phenom II X4 940BE!

Here it is:


and here you can see how nicely it looks in a socket:


I've spend some time running power consumption and benchmark comparison between Phenom 9950BE @3.0GHz NB2.0GHz RAM 1066MHz 5-5-5-15-25 2T and Phenom II X4 940BE @3.0GHz NB2.0GHz RAM 1066 5-5-5-15-25 2T

Note: For power consumption tests my HD4870 is clocked 625(500MHz desktop)/465MHz to save power. Everything else as in my SIG. RAM set in BIOS @2.05V
For game and application testing my HD4870 is set to 825MHz/950MHz
All tests are run on Vista Business x64 SP1 with all latest patches. Power options are set to High Performance which means C'n'Q is DISABLED!
Every test was ran at least 2 times and second test result was taken to minimize HDD activity influence on scores.
Cooling: AIR TT120Ultra + 120mm FAN 12V, ambient temp for first runs on Phenom 9950 around 16C-17C, later runs were 19C-21C.

Below are my findings:

Lets start form Power Consumption:


Phenom I 3GHz/1.32V after 15min. full load - 283Watt




Phenom II 3GHz/1.36V after 15min. full load - 241Watt




Special for BertM
Phenom II 3GHz/1.32V after 40min. full load - 233Watt (Higher NB @2.2GHz/ RAM@2.15V instead 2.05 like for previous runs - I will re-run this test properly later)
EDIT re-tested with 1.32vCore NB@2GHz RAM@2.05V - 230Watt



Phenom I 3GHz/1.32V idle - 238W



Phenom II 3.0GHz/1.36V idle - 190Watt



Phenom I 1.2GHz/1.05V after 15min. full load - 206Watt




Phenom II 1.2GHz/1.05V after 15min. full load - 185Watt




Phenom II 1.2GHz/1.05V idle - 176Watt



----> Undervolting<----


Phenom II 1.2GHz/0.88V after 15min. full load - 179W




Phenom II 1.2GHz/0.8V after 20min. full load - 177W

----> SUMMARY<----




First impression is very positive! Just look at LOAD power consumption between Phenom 9950 and 940. What's amazing is that at 3GHz old CPU needs as much juice in IDLE as new one FULL LOAD!
Then there is undervolting and another big surprise. This CPU can reliably operate at only 0.8V 1.2GHz. I have tried 1.4GHz but this ended up by BSOD.
In my short performance review I've tried to use applications different than rest of my colleagues. But even old games like Q2/Q3 and applications improved IPC by 5-15%! Newer applications which are designed with SSE and larger caches in mind can extract even greater boost from tweaks AMD did to Phenom II!
I'm really happy with my new CPU and finally I can utilize this great motherboard in a way I was intending from beginning.

Quick few words about OC. HTT clocking is much easier with new Phenom II, I've struggled to get 230HTT on older CPU, but 267HTT was quite easy with new processor. AOD is working great, except a bug with false clock reading, but this can be fixed by loading BIOS defaults. I'm still exploring limits of my sample on AIR, but so far 3.8GHz CPU 2.9GHz NB looks to be stable. 3.93GHz Cinebench stable for now and finally 4GHz+ only for SuperPi or other single threaded apps.

I hope you enjoyed my tests and that it will help few people make their minds!

argh 40 links :p
no problem with me if you show all the pics in this thread, im to lazy at saturday evening
how much power consumption does it take less if you bench the deneb at 1.3 volt at 3ghz?
ah k your still editting. 3 watt less, didnt expect that. cpu probably takes 95-85 watt there.

here is another stock voltage from me
( overdrive showed wrong values in its right colomn so i put cpuz over that to prevent confusion.

[BertM]

no i cant get them all there but 3410 seemed good for 30 minutes prime
http://www.xtremesystems.org/forums/...&postcount=949
im interest for now only in stock voltage oc's or little above or below stock voltage.
atm im priming 3410 at 2200 northbridge. this resulted in 20.234 superpi.
edit: ah bah error after 4 minutes, enough for today.

Special for BertM
Phenom II 3GHz/1.32V after 40min. full load - 233Watt

I've done 1h OCCT @3.4GHz NB2.2GHz stock volts




Now it's time to clock this baby!
I will report shortly ...

[BertM]

did you use more voltage on the northbridge ?
i upped the nb core a notch, the nb vid seems stuck.

No, not yet. I've just changed NB multi to 11x in BIOS.

[BertM]

ah yes that seems longer stable now.
i used 10 multi and higher htt 215 or something. that was not stable.

edit: i could be mistaken but cpu seems to be cooler at htt around 200.
im now priming 3535mhz with 2222mhz nb and 202mhz htt.
this was 19.6 seconds superpi.
it could also be that this mobo doesnt like to be high htt stable. i noticed that with the 5000be.

[Lightman]

Before I went to bed I've did quick OC session and managed:
220HTT / 3740MHz(1.46V) cores / 2420MHz(1.225V) NB - 15min stable (played Crisis, CB2003x64, CB R10x64, SuperPi, etc...)
200HTT / 3820MHz(1.46V) cores / 2212MHz(1.225) NB - 10min stable (played same games as above )

Then as a final move before leaving to bed I've looked for 1.46V clock limits and set CPU to 4070MHz - 5 sec. and reboot
Looks like I will need more volts for 4GHz ...
Will see tomorrow

This morning I finally received my Phenom II X4 940BE!

Awesome power figures, I would be curious to know the undervolting ability of the 940 at 3.0ghz. How low can you push that vcore, and how does it influence power?

Ok!

All settings like before and at:
1.25V full load - wall 223Watt - this is fully stable
1.20V full load - wall 218Watt - this is fully stable as well
1.15V full load - wall 214Watt - this is not stable (crashed after 25 minutes of stress)

Hope that helps!

awesome! Very good to know. So, that's ~15W savings from full load with 1.35v?

You have no idea how awesome it is to an old Slipgater like myself that you benched a Quake game. Kudos to you, good sir.
