ctach me up to speed

1) what is all this CORE stuff about, never heard of it until I saw a link for it somewhere. I checked the site and did some reading, but was only left confused.

2) I'm guessing looking around that amd lost its performance crown, when and how did that happen, last I checked intel had nothing.

3) whats the top end for each company and how do they compare?

I really have no idea how long i've been out of the loop, I think I remember the dual core athlons coming out, and something about smithfield.

core2 duo 6400 (2.13ghz) ($210) = amd fx62 (2.8ghz) ($800) Its a dual core, 65nm (overclocks easily to 3+ even some 3.5 ghz) and I'm guessing 25% more efficient for same ghz than a64 x2.

x6800 (2.93 ghz, around $1k) about 30-40% (sometimes more) faster when using cpu intensive stuff than fx62

 

[miketheidiot]

um, wow

that would explain the lac of amd threads.

so i'm going to take a shot in the dark and say that this is not netburst based?

Yes, its back the the P3 type chip, but even better. I am AMD fan (as you can see) but Core 2 is a great chip. I have 2 already.

What I/we tell everyone who asks: if you're building a new system, build a Core 2 Duo-based system. If you've already got a decent Skt 939-based system, don't feel bad about buying an X2 to put into it, now that they're finally affordable.

And the FX-62 is faster (though not by much) at almost everything, than an E6400, though it is slower at nearly everything, than an E6600. I don't say that to argue with lyssword, just to clarify a little.

 

[miketheidiot]

So would this be a desktop banias(sp?)/dothan line?


On a more technical issue, what exactly make for this 30% advantage per clock, assuming this is a more advanced Pm design, whered the speed boost come from, those things were just barely slower clock for clock than k8 chips. I'm glad I sold my AMD stock when i did .

The big thing here is, that overclocked, a 6400@3.5 (which isn;t too hard) will wipe the floor with and FX-62 @ 3.2 (which is harder to hit)

Anandtech has a good review of the core 2 launch and comparisons.

Thank you, Captain Obvious.

I'm not quite sure of all of the technical part of it but...
The speed boost comes from a redesigned/redefined/slighty-new architecture. Maybe myocardia can explain more...he seems to know a bit more about the architecture designs used and so on.
