With anticipation for Apple's iPhone 5 (or whatever branding is ultimately used) extremely high, most of the focus has been, not surprisingly, on design and timing. But what will make the iPhone 5 tick? That's the question I asked a couple of experts.
The upcoming phone is expected to pack Apple's latest and greatest A5 silicon, a Qualcomm 3G chip, and circuits that support a higher-resolution camera.
A5 chip: The Apple A5 houses the main processor--or so-called application processor--that will power the phone. The A5 (technically a system-on-a-chip or SoC) is the same chip that currently powers the iPad 2. The A5 distinguishes itself from the older A4, used in the iPhone 4, by having two processor cores (the A4 has one) and faster graphics circuits. Two cores allow the device--like the iPad 2--to multitask better than a single-core phone.
"It's liable to be the A5," said Will Strauss, president of Forward Concepts, a company that tracks the phone chip market. But Strauss expects the chip to be a variation of the A5 in the iPad 2. "It's a geometric shrink of the A5. The geometries (size of the chip) will be smaller," he said. … Read more
