Intel today launched a 2GHz version of the Pentium 4-M, its fastest mobile CPU to date. But it ain’t cheap, priced at $637 for 1,000 units. The new 1.9GHz P4-M is a bit pricey too, tipping up at $401 in OEM quantities. So it’ll be a little while before either chip hits the mainstream – but maybe not too long the way Intel is managing production ramps right now. Also a 2.2GHz P4-M is scheduled for Q4, which will mean price cuts down the line to pave way for the new model.
