Overclocking
Global Foundries has been hard at work. While most of its public discussion has been about ARM and 28nm, AMD’s foundry partner continues to crank out 45nm SOI parts. Overclocking in general has improved on AMD’s CPUs as GF’s 45nm process is fairly mature.
When I reviewed the Athlon II X2 255 in January I indicated a 3.7 - 3.8GHz overclock was within reason. My Athlon II X2 265 sample managed 3.89GHz:
Moving up the totem pole the Athlon II X3 450 topped out at 3.692GHz:
The Athlon II X4 645 managed a 22% overclock to 3.789GHz:
Our best overclock with the stock cooler came from the Phenom II X4 970 at 4.1GHz:
Finally we have the 1075T that managed a 4GHz overclock, although I wasn't convinced of the overclock's stability in my tests - dropping down to 3.9GHz is probably a safer bet in this case:

OMG YOURRRR SO INSITEFULLL!!!11111Learn to spell, moron.

I just bought the 95W version of the 1055T and it took a few months for it to be available. I put it in my ECS A780GM-A Black Edition Motherboard and it works for awhile then the screen goes blank.Going to have to get a new motherboard. So much for backward compatibility with AM2+ socket.

I have seen a few desktops form OEMs featuring an AMD Phenom II X6 1035T.Is this an OEM only CPU ? Could you include it in your performance charts? Thanks

The 970BE looks interesting especially if it has headroom for more OC.coronaJet - Monday, October 4, 2010 - link
I think its astonishing, that the new Athlons X2 and X3 have lower power consumption than the old ones, even if they work at a higher frequency.How is that possible? Is that a new stepping or better voltage magagement ?

Looking at these charts. The Core i5 750 consistently beats the X4 970 and they're priced to compete against each other. Not only does Intel win more, but they win in all the areas that really matter to me; not to mention the power consumption advantage.Secondly, where AMD actually does very well, encoding video, that advantage is negated by the fact that regardless of how good the CPU is a encoding and rendering video doing those things on the CPU is almost entirely obsolete. I know I do all that stuff using my Nvidia GPU and it's exponentially faster.
In other words, AMD can't win anywhere at a similar price compared to intel. The ONLY reason I can see buying an AMD CPU and that price point right now is if the CPU is all your changing and you already have an AMD Motherboard. Unfortunetly for AMD if you're building a whole new system Intel is the way to go and every price point with decent profit margins.

Ivy Bridge is meant to be still on track for 2H 2011. This just seems crazy. Intel are not going to release a whole new generation in Sandy Bridge and then replace it within 6 months!??I guess they might just release a few 22nm parts like they did with 32nm but even that seems so unlikely right now. I mean we won't even have high-end Sand Bridge parts out yet and we will have the replacement for Sand Bridge at our door step!
Anyone know what is really going on?

I am quite confused as to WHY Athlon II X3-450 with higher speed is actually cooler and more efficient than X3-440? Also, the same between X4-645 and X4-635?!I thought they're all the same core, no?
If these are more efficient, are they ideal for HTPC stored in a cabinet? using Antec Fusion Case?
