If I've understood correctly, the N450 package deal includes faster graphics, and it uses less power. Otherwise I'm troubled by reports that indicate that the actual processing capability is no more than the Celeron M (?) in my old Samsung Q1 tablet UMPC from -way- back, despite a much higher clock speed. Except that, using less power, the computer goes on processing for longer, of course.

Clarification needed: the Atom N450 is a single-core CPU. And Engadget reports: "the even faster N470 chip will start making the rounds in March 2010". But: how is the single-core Atom N400 series better than the dual-core Atom N300 series? And the Atom N500 series is either: (some say) "dual-core"; other sources say the Atom N500 series is still single-core, but (different from the N400 series) just has Hyperthreading enabled:

These Atom CPU's all seem to be 45nm designs. Is there an Intel roadmap for a 32nm (genuine) dual-core (+ Hyperthreading enabled) Atom CPU?
Also: any chance that an ATI video solution might surface in a Netbook? As competition for the ION chipset.

There's almost zero difference. Sure, Intel is claiming that these new Atoms are a major upgrade, but if you take a look at the specs you'll that almost no performance benefit and these are still mainly 32-bit without virtualiztion and no core improvements. Intel doesn't want to cannibalize their real laptop processors (Core, Pentium, Celeron) so they're barely improving Atom.

I'm sure people are wondering what's the material difference between an N450 and whatever kind of Atom they are selling now?
