Future Windows 8.1 tablets will be powered by the marquee attraction at Intel's annual forum that starts Tuesday -- the Bay Trail Atom chip.
What is Bay Trail exactly? At the high end, it is a series of Atom processors built primarily for tablets. (Lower-end Celeron and Pentium variants should appear in low-cost laptops.)
Maybe most importantly, it's a completely redesigned Atom that is trying to break from the past of pokey Windows 7 Netbook Atoms.
