More interesting to me in this regard are the "4+1" cores. The +1 is a low-powered standby core. I don't know if it's new, but if not, it could change the batte

  The Tegra 3 had this feature and appears to work relatively well according to http://www.anandtech.com/show/5779/htc-one-x-for-att-review/3 http://www.anandtech.com/show/5779/htc-one-x-for-att-review/...

    If i'm not mistaken, that review is for One X for att, which doesn't have Tegra 3 in it. It does have data for Tegra 3 (One X international version), but it doesn't seem to support the claim that Tegra 3 is more power efficient because of the +1 core.

      Maybe not more efficient than everything else out there, but more efficient than if it used 4 cores only - especially at that 40 nm process. I think Samsung's Exynos processor was a bit more efficient, even though it didn't have the 5th core, but it was made at 32nm.

  It's not new, it's in tegra3 also. I never saw real profiling data/usage report regarding how effective this "+1" core is in saving power. But I did saw anecdotal report that the "+1" core often times works at the wrong time that hurts performance... (e.g. still used despite of heavy load, etc. )
