Silvermont: Intel's promise to power phones and tablets you'd actually want
Today, nearly all modern smartphones use an ARM-based processor, along with every iPad and practically every Android tablet as well. Soon, though, Intel's x86 silicon might finally pose a challenge. Six years after laying out a roadmap for power-efficient processors for tiny computers, and several failed attempts to make a real dent, Intel impressed us last October with just how power-efficient its Medfield chip could be compared to the latest Qualcomm Snapdragon. That chip used the company's Saltwell core inside, but this year the company's introducing Silvermont, and Intel claims the new 22nm architecture will more than hold its own against the best ARM has to offer.
Intel promises three times the performance, or the same performance at five times lower power than the current gen Atom core, a truly serious boost. In charts (see below), Intel showed us how its dual-core processor can theoretically trounce the competition's quad-cores at one watt, and how a quad-core Silvermont-based chip, like the Bay Trail that will appear in tablets and cheap notebooks late this year, should be able to wipe the floor with the competition with just 1.5 watts of power at its disposal. "If you have an efficient solution, you don't need to play the core count game," Intel Fellow Belli Kuttanana told reporters at a press conference.
and didn't Medfield prove it in Razr-I vs Razr-M comparisons ? Even now the Razr-I can still beat the latest S4 in battery endurance. Those Medfield charts were done against existing competition and even now it can be found at the top of charts unlike its contemporary dual-core A9s.
If we assume that tablets today are "fast enough" for the light content consumption most people are using them for today then it would make sense to configure the Intel tablet for the equal performance and get the 3-5 times battery life compared to existing ARM tablets. In this example for instance, the Intel tablet function an entire business week on a single charge whereas the ARM tablet would have to get charged every day.
The Intel tablet would much better to travel with. Most business trips are three days or less, wouldn't even have to bring the charger.
