IntoMobile really, really believes there is a big future in multi-core iPhones. We agree, but just aren’t sure the battery technology is there yet (for June iPhones that are running around South San Francisco). One of ARM’s strengths is the ability to idle at incredibly low power rates then step up the power usage incrementally based on the CPU needed.
Would you give up a few hours of battery time to be able to play graphic-intensive video games on your iPhone? – That’s what you’d get with Multi-core. With a solid single core Cortex A8 architecture (Like the Pre) Apple’s browsing and gaming experience would improve without cost to the battery life.
