Pretty much. Some motherboards can attempt to unlock the CPU's L3 cache. If successful, performance to very close to that of a Phenom II at the same clock speed.Since the L3 cache on those CPUs is essentially their version of L2 cache (since their L2 cache is so small), you can sort of consider this a Celeron, or Sempron, of sorts.
According here AnandTech: AMD Athlon II X4 620 & 630: The First $99 Quad Core CPUSeems like a nice competitor for the Q8200, though that one can be OC'd to 2.8GHz easily so it steps away from it. I wonder how these OC.
So yes, if you factor overclocking it currently destroy Intel lower end quad core for price/performance and even more so if you don't.As I mentioned at the start of this article I managed to hit 3.25GHz on the Athlon II X4 620 without any additional voltage using the retail AMD cooler:
No. Check this.lol dude these are 45nm. 3.8 ghz is probably the limit on air.
The last part is the key. I'm not sure how voltage goes with AMD, but with Intel, 1.4V is about the considered limit for 45nm. They're already there with just 3.25GHz (I'm running 4.0GHz right now with 1.23V). Now I know it may be, or should I say I'm pretty sure it is, a bit different with AMD than it is with Intel, but I'm sure the limits aren't too far apart, and since it's different, you can't assume it'll get to near 4GHz just because Intel does. A Core 2 is a much different 45nm chip than a Athlon II is.I could hit 260MHz x 13.0 for 3.38GHz by upping the voltage, but the gain wasn't worth the additional power usage. Anything higher wasn't possible without more exotic cooling or much more voltage.
