Intel Has recently announced that its new upcoming chips of Haswell series will draw 50% less power than the previous gen Ivy Bridge Chips. Haswell is the fourth generation Intel core i Processors scheduled for the fall 2013. Mobile devices like Ultrabooks & Laptops are exppected to get a huge advantage from the highly energy efficient Haswell chips. But the most astonishing part of the statement is that its chips will draw “50% less power” than Ivy Bridge on “active” workloads, such as playing a game or watching a movie.
On the otherside Intel also has published that Haswell’s idle power consumption is 20 times less than Ivy Bridge. This means that the fourth-generation Core-based products will provide the biggest battery life increase in Intel’s history,” the general manager of Intel’s architecture group, Rani Borkar, told reporters
Borkar went on to say that the lowest-power Haswell chips, which are probably destined for expensive tablets (such as the Surface Pro’s successor), have a TDP as low as 7W, down from 10W for the most conscientious Ivy Bridge parts.
Ivy Bridge used the same architecture as the sandy Bridge but shrunk to 22nm. Haswell is an entirely new architecture that’s designed from the ground up to make use of Intel’s 22nm FinFET transistors. Improved power gating, lower-power modes, and getting into low-power modes quickly is a a significant focus of the Haswell architecture.
We expect Haswell to be a beast of a chip. It probably won’t make huge waves on the top end (expect a 10% improvement over Ivy Bridge), but it really does look like Haswell will be incredibly power efficient. Whether this is the chip that boots ARM out of the tablet space, or whether that’ll be Bay Trail or Broadwell (Haswell’s 14nm successor), remains to be seen.
