Intel’s Silvermont Architecture Revealed: Getting Serious About Mobile

In the interests of preempting some of the incredulous butthurt that using Intel's numbers is sure to cause.

A quote from the article.

That’s the end of the Intel data, but I have some thoughts to add. First of all, based on what I’ve seen and heard from third parties working on Baytrail designs - the performance claims of being 2x the speed of Clovertrail are valid. Compared to the two Cortex A15 designs I’ve tested (Exynos 5250, dual-core A15 @ 1.7GHz and Exynos 5410 quad-core A15 @ 1.6GHz), quad-core Silvermont also comes out way ahead. Intel’s claims of a 60% performance advantage, at minimum, compared to the quad-core competition seems spot on based on the numbers I’ve seen. Power is the only area that I can’t validate based on what I’ve seen already (no one has given me a Baytrail tablet to measure power on). Given what we know about Silvermont’s architecture and the gains offered by Intel’s 22nm process, I do expect this core to do better on power than what we’ve seen thus far from ARM’s Cortex A15.
