Atom's HTT is actually pretty good - I saw up to 25% more performance
simply by using multithreading in 7zip's compression benchmark (on
WinXP, though). Of course, OTOH it uses about that much more transistors
on the CPU die so it's not exactly free performance.
really that much? i thought

Netbooks based on Intel's Atom microprocessor are turning into
big hits this Christmas season. The Atom, a super-low-power x86
processor, is an in-order machine, which means that except for a
few special cases it can spend a lot of time waiting for data to
arrive when it encounters a cache
