Ok i may not be updated well in the cpu department but last year when i built my rig, i had gotten a core 2 duo e6400, and now i see these diff numbers and quads and what not. Basically watever happened to the 6400,6600's etcs? And how do they compare now to the ones that are currently out?

The main difference with the ones that replaced the 6400 and 6600's were a 1333FSB instead of the 1066 of the others. 6550 and 6750 are the "replacments" then the 6700-6850 the GHZ ratings are slighty different though obvisouly with different FSB's

They all have unlocked multipliers? I thought only the overpriced extreme editions were unlocked.

To understand the numbers:

E6300 1.8ghz 2MB L2
E6320 1.8ghz 4MB L2
E6400 2.13ghz 2MB L2
E6420 2.13ghz 4MB L2

Those are still on the rated FSB 1066mhz. The E6300 and E6400 are being fazed out, and being replaced by the E6320-E6420.

Q6600 is a quad core, but still runs on a rated FSB of 1066.

The other: E6650-6850 have a faster FSB of 1333mhz.

So the E6320 and E6420 just have more L2 cache that will improve only on certain apps for about 3 to 5 percent gain, if I remember correctly.

As far as the unlock mulitplier, to go above the stock multiplier, it has to be the extreme edition CPU, from what I understand. All the others are unlocked going down, so for example if your stock is 10 (like my E4400), you can go down to a mulit of 6 for speed step to conserve power.

Yeah, only the extreme edition ones have unlocked multipliers, all the others are locked. They're unlocked if you want to go down, but the older C2Ds were the same.

Barcelona is a nice city in Spain, and the Barcelonas from that city are pleasent.

Oh, you mean the AMD Barcelona? Last I heard, AMD had such locked down NDA's on it that no one has been able to publish a non-AMD approved review since its arrival. That way, no one can ever know how it compares in a real test against an Intel chip. At least, that's the last I heard. Maybe there is an independent review out there that I haven't seen. Can't say anything about that. So the AMD Barcelona is a great unknown.
