With the Atom dominance expected to continue, even with the competition from ARM, VIA and others, Intel is reported to be planning the introduction of a 2.0 GHz version of its low-power 45nm CPU. Named Z550, the MID-targeting processor would start selling next month and have 512kB of L2 cache, a FSB of 533 MHz and a TDP of 2.4W, just like its brothers, the 1.86 GHz Z540, and the rather popular 1.6 GHz Z530 which is used in a few netbook models on sale today.

I'm running MSI Wind @ 1.92Ghz with a simple push of a button!
doesn't do much performance wise though
