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 mayb

I know there was a lot of changes made in the n

Yes, but that is a hardware problem which is independent of the

"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
