A buddy of mine is wanting me to build him a system, and he is partial to AMD cause they are generally cheaper. But my only experience is with intel so far. Anyway, I was wondering what AMD's top dual core is for overclocking. I know AMD is doing a lot of Quad core stuff right now, but I had heard that they were going to be putting out a 4.0Ghz dual core pretty soon. Is there any truth to this? And if not, what is the best current 45nm dual core they have, and how well do they typically overclock?

The top dual core is the Phenom II 550 BE.

They usually fall short of 4GHz due to their cripped IMC and it having issues with 64 bit operating systems.

Both overclock well. The 965 to 3.6, 3.8 is least. I doubt they will put out a 4 ghz anything.

So you havent read the news about the C3 965s huh?

So the 550 BE. I am looking to reach 3.8Ghz on air. Think it's possible with that processor? And I did notice one thing about it.. it seems to have a low cache, equal to my lowly intel e4300. Think that could hurt the benchmarks? (on all max graphics settings) Or could it affect gaming in any way?

3.8GHz on air may be a bit of a challenge, you'll need a good air cooler. That said, it is doable.

what are these 64bit issues you speak of? :S

Your CPU doesn't have L3 cache now does it?

3.8Ghz via air is easy on an aftermarket cooler

Have you found a nice aftermarket cooler to use yet?

How is 3.8Ghz on air a challenge?

Like I said, it's one of the lower intels. As in, they don't even make it anymore. So please don't start the whole underdog debate. That's not what this thread is about. I'll never understand you amd fanboys

I'd get a 720BE. You'll see ~3.6GHz easy on it. Possibly 3.8 with a good cooler. And, if your lucky, you'll get one that'll unlock into a quad.

Maybe I am misunderstanding, but it sounds like AMD doesn't make a dual core anymore, that isn't just a quad with 2 locked cores. Is this true? I would prefer a true dual core for the build if possible.

I only know about Deneb and Propus cores (both are quads). With the other 2 cores disabled it really wouldn't consume more energy than a native dual-core CPU.

The vcore needed, and thus temps on the 550.

I think some of the Athlon IIs are native dual cores, but the more experience guys can correct me on this one if I'm wrong.

yes

athlon II x2's are regor and so is the sempron 140, ACC can enable the second core with some luck.

the ahtlon II 250 X2' 3.0ghz regor unlocks with ACC to an unlock multiplier.

regor has 1Mb L2 cache. AMD cores aren't cache hungry, more like sub zero hungry.

They still have Nb speed to balance out with the core, but no L3 cache.
