The Athlon II X2 & Phenom II X2: 45nm Dual-Core from AMDby Anand Lal Shimpi on June 2, 2009 12:00 AM EST

Both the Athlon II X2 and Phenom II X2 are light on the power consumption. Our Athlon II X2 sample actually drew more power under load, possibly because of its larger L2 caches which operate at full clock speed rather than at the 2.0GHz un-core clock of the Phenom II's 6MB L3. Alternatively, it could just be poor BIOS power management support for the Athlon II at this stage.

vajm1234 - Tuesday, June 2, 2009 - linkits really hard to believe ad a lil concern for upcoming c2d processors --- why that 6300 sample didnt overclock? wat was wrong 3.7 i xpct normally but i m amazed as its a 45nm.... not 90 or 65

ShawnD1 - Tuesday, June 2, 2009 - linkI like how you included the overclockability at stock voltage. Since all of my computers use stock heatsinks, overclocking at stock voltage is pretty much all I can do.
Gary Key - Tuesday, June 2, 2009 - linkI used the standard heatsink off the Phenom II 940 on the X2 250, 1.4V, and hit 3.825GHz in Win7 64, idle temps around 33C, full load at 54C. I have retail CPUs coming with the new cost reduced heatsink to see what happens but any stock AM2+ heatsink from a Phenom/PhenomII works wonderfully for overclocking these two CPUs.
RamarC - Tuesday, June 2, 2009 - linkI know AMD has 'nudged' mobo makers to prevent this, but some still allow it. I'm curious why Anand didn't experiment with it.
AnnonymousCoward - Wednesday, June 3, 2009 - linkI figured those extra cores have defects.
Anand Lal Shimpi - Tuesday, June 2, 2009 - linkIt's more of a timing issue than anything else. I spent a lot of last week working on Lynnfield and there's one more CPU review before this week is up. I am curious about it and will look into it shortly though :)
flipmode - Tuesday, June 2, 2009 - linkHi Anand. Great review, it is much appreciated. The first thing I looked for was a comparison to the Brisbane CPU. To me, a comparison to Brisbane and a comparison to Penryn are the two most interesting.
ltcommanderdata - Tuesday, June 2, 2009 - linkI'm guessing if Phenom II X2s use harvested cores, they'll eventually be a limited commodity. Still, the Athlon II X2 seems to have a lot of scaling room left so higher clocked Athlon II X2s will probably do just as well.
I just flipped through the benchmarks this morning, but since I was one of those commenting on wanting to see the best of dual core Netburst processors like the 965EE for comparison, I wanted to thank you for deciding to include the 955EE.
ltcommanderdata - Tuesday, June 2, 2009 - linkAs a follow-up is AMD still making 90nm dual cores or have they converted the fab to 45nm now? I believe the previous fastest dual core was still the 3.2GHz 90nm Athlon 64 X2 6400+. It's too bad it wasn't included here.
