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.)
Bay Trail uses so-called "out-of-order execution," analogous to what Intel uses in its higher-performance mainstream Haswell processors. It also packs improved graphics silicon -- to cite just two high-profile features.
But the proof is in the pudding, of course. Early Intel-generated benchmarks hint at the stepped-up performance.
Anandtech posted Intel benchmarks that compare a current Clover Trail Z2760 to a future Atom Z3770 that show "nearly 3x the performance."
"Obviously the big unknown here is power consumption. As Bay Trail is destined for tablets, I'd expect lower average power than pretty much all of our comparison targets in the graph," wrote Anand Shimpi. (See graph at bottom.)
And a recent post from graphics chip expert Jon Peddie said Bay Trail "handily runs Windows 8.1," citing similar Intel benchmarks.
"It's very respectable but not a mind blower," Peddie said in a phone interview.
Benchmarks, however, are just benchmarks and don't guarantee vastly better performance for the consumer and/or success in the market.
Windows 8 device makers will need to produce stellar designs to match the better performance in order to make any inroads against Apple and Android.
