原创 Apple considers replacing Intel chips

When Apple Inc. dropped IBM processors for Intel chips in its venerable Macintosh computer line almost seven years ago, it was a big deal.

The late Steve Jobs and Paul Otellini, president and CEO of Intel, appeared on stage together at Macworld 2006 to make the surprise announcement—with Jobs' typical flair—that iMacs with Intel's Core Duo processors were available immediately, six months ahead of schedule. Two of Silicon Valley's most famous and successful companies were finally getting together.

But now it appears that that run may be winding down. Last November 5, the Bloomberg news service reported that Apple is exploring ways to replace the Intel processors it uses in Macs with some version of the A5 and A6 SoCs it uses in its iPhones and iPads. The Bloomberg story, which cited unnamed sources "familiar with the company's research" said Apple engineers have grown confident that the chips it uses for its mobile devices will one day be powerful enough to run desktop and notebook PCs.

Recall that a few weeks Apple showed the door to two senior executives and reshuffled responsibility for several of its divisions. The company seemed to take pains to include in that announcement the cryptic statement that Apple's semiconductor teams—which now report to Senior Vice President Bob Mansfield—"have ambitious plans for the future."

Retooling Apple's ARM-based A6 to power PCs would certainly qualify as ambitious. It would also be consistent with Apple's modus operandi in recent years—moving towards vertical integration and greater control over the chips it uses in its products. It would, of course, require a great deal of work on both the hardware and software sides.Such a move, however, would not occur overnight—it would likely take Apple several years.

For Intel, it is unclear how large of a blow such a move by Apple would be. Apple—with its wild success and iconic products—is a prestigious logo to include on the customer slide in a Powerpoint presentation. But Intel's biggest customers are Hewlett-Packard Co. and Dell Inc. Apple sold 4.9 million Macs in its most recently concluded quarter; HP shipped 13.6 million PCs in the third quarter, while Dell shipped 9.2 million.
