Apple Computer plans to announce Monday that it's scrapping its partnership with IBM and switching its computers to Intel's microprocessors, CNET News.com has learned.
Apple has used IBM's PowerPC processors since 1994, but will begin a phased transition to Intel's chips, sources familiar with the situation said. Apple plans to move lower-end computers such as the Mac Mini to Intel chips in mid-2006 and higher-end models such as the Power Mac in mid-2007, sources said.
The announcement is expected Monday at Apple's Worldwide Developer Conference in San Francisco, at which Chief Executive Steve Jobs is giving the keynote speech. The conference would be an appropriate venue: Changing the chips would require programmers to rewrite their software to take full advantage of the new processor.
IBM, Intel and Apple declined to comment for this story.
The Wall Street Journal reported last month that Apple was considering switching to Intel, butciting the difficulty and risk to Apple.
That skepticism remains. "If they actually do that, I will be surprised, amazed and concerned," said Insight 64 analyst Nathan Brookwood. "I don't know that Apple's market share can survive another architecture shift. Every time they do this, they lose more customers" and more software partners, he said.
Apple successfully navigated a switch in the 1990s from Motorola's 680x0 line of processors to the Power line jointly made by Motorola and IBM. That switch also required software to be revamped to take advantage of the new processors' performance, but emulation software permitted older programs to run on the new machines. (Motorola spinoff Freescale currently makes PowerPC processors for Apple notebooks and the Mac Mini.)
The relationship between Apple and IBM has been rocky at times.for chip delivery problems, though Big Blue said it . More recent concerns, which helped spur the Intel deal, included tension between Apple's desire for a wide variety of PowerPC processors and IBM's concerns about the profitability of a low-volume business, according to one source familiar with the partnership.
Over the years, Apple has discussed potential deals with Intel and Advanced Micro Devices, chipmaker representatives have said.
One advantage Apple has this time: The open-source FreeBSD operating system, of which Mac OS X is a variant, already runs on x86 chips such as Intel's Pentium. And Jobs has said.
The move also raises questions about Apple's future computer strategy. One basic choice it has in the Intel-based PC realm is whether to permit its Mac OS X operating system to run on any company's computer or only its own.
IBM loses cachet with the end of the Apple partnership, but it can take consolation in that it's designing and manufacturing the Power family processors for future gaming consoles from Microsoft, Sony and Nintendo, said Clay Ryder, a Sageza Group analyst.
"I would think in the sheer volume, all the stuff they're doing with the game consoles would be bigger. But anytime you lose a high-profile customer, that hurts in ways that are not quantifiable but that still hurt," Ryder said.
Indeed, IBM has a "Power Everywhere" marketing campaign to tout the wide use of its Power processors. The chips show up in everything from networking equipment to IBM servers to the, Blue Gene/L.
Intel dominates the PC processor business, with an 81.7 percent market share in the first quarter of 2005, compared with 16.9 percent for Advanced Micro Devices, according to Dean McCarron of Mercury Research. Those numbers do not include PowerPC processors. However, Apple has roughly 1.8 percent of the worldwide PC market, he added.
Apple shipped 1.07 million PCs in the first quarter, and its move to Intel would likely bump up the chipmaker's shipments by a corresponding amount, McCarron added.
