"do you think DC will be more sought after than 64 bits? I think the opposite."

I agree with you and had a long discussion with Keith on this very issue. Neither one of us convinced the other.

Re: do you think DC will be more sought after than 64 bits? I think the opposite.

In terms of the actual terms, both are equally sexy, but the real difference comes in the fact that dual core benefits exist today, while 64-bit benefits do not. You make the argument that 32-bit processors won't be able to access the 64-bit features of Vista, but so far no one has listed which features these will be. There will be a 32-bit version of Vista, and what if it has 95% of the features in the 64-bit version? It would make the 32-bit argument silly.

Moreover, single core processors are never going to be able to get the benefit of dual core processing as more dual core applications become available, so how is that different than 32-bit processors lacking the capabilities of 64-bit apps? Seems like the same scenario to me, but at least it will take years and years before 32-bit apps start getting phased out, and by then it would be completely irrelevant to base today's buying decision on that scenario.

Consider:

Performance for all x86 CPUs is marginally decreasing. Large increases in performance can only be had via DC.

DC is the "same" price as SC.

DC gets you availability until DC software.

It's required for VIIV (says Intel).

FAPP, there is no 64 bit software...

gollem, on dual core vs. 64-bits

drjohn, do you think DC will be more sought after than 64 bits? I think the opposite.

If I may stick my neck in here, why would anybody think they can know which will be more desirable over the life of their purchase? Who knows the right answer?

But I *do* know that the dual core Turion due out in less than 6 months will offer both. That's the way I'd bet.
