Then I'm afraid you have unrealistic expectations. A 3GHz Allendale will easily keep pace with a 3.6GHz X2. Seeing how a 2.94GHz E6300 outpaces a 3GHz X2 by an average of 20%
<a target=_blank class=ftalternatingbar...es/cpu/display/core2duo-e6300.html</a>">Xbitlabs comparison</a> I don't see how you came to your conclusion. Allendale is at least 20% faster clock for clock against X2, and Conroe is around 25% faster clock for clock.
Why would you say that they can't clock 65nm faster than 90nm? That really makes no sense (typo?). If you are referring to the fact that they aren't releasing 65nm at a faster clock than 90nm initially, this is bog standard practise for both Intel and AMD...I can't think of an exception to this.
I meant that people shouldn't expect miracles from a die shrink, especially at launch. The primary benefit from a die shrink is to cut manufacturing costs and reduce power consumption
Look how much 90nm helped compared to 130nm for K8. Correct me if I am wrong, but 130nm K8s overclocked to around 2.4GHz on average. 90nm K8s are overclocking to around 2.8GHz on average. That's about a 400MHz boost from a die shrink, so unless AMD worked some miracles I don't expect to see 3.5 - 4GHz overclocks from a 65nm X2 anytime soon. Of course, I'd love to be proven wrong, increased competition between AMD and Intel can only benefit us as consumers, but realistically that's not going to happen until K8L.
I agree that the C2D core will still remain much better at equal overclocks, but you're wrong about it not having an effect. The OC market looks for the best bang for the buck, not just the fastest chip...
I personally don't have a clue how well it's going to perform on OC, but as AMD has already released a 3 GHz on 90nm, a 33% OC after a node change to hit 4GHz seems very possible.
My point was that you should stop making up your mind before we actually see the thing...
The only 'effect' 65nm is likely to have is on AMDs bank balance, which is a good thing of course. A healthy AMD = healthy competition.
The OC market is after best value of course, but I don't see what anything AMD has to offer that can beat a $150 E4300 in that respect. The lower FSB reduces the need for a costly mobo and high speed RAM, thus reducing platform costs to comparable levels to AMD's offerings.
I haven't 'made up my mind' regarding 65nm K8, I just don't share the same rosy outlook you have for them.
I do hope they will clock up to 4GHz as you mentioned. That would be friggin awesome and open the enthusiast market right up. I just don't think that's very likely, at least not in the short term.
BTW may I mention that the link TheINQ provided shows a 90nm X2 4200+, not a 65nm... go figure.
