Rumours have began to surface about Apple currently developing ARM-based devices, primarily Macs.
These rumours apparently have been circulating for years now, with current rumours stating they have long been in the works. According to French Apple enthusiast site MacBidouille, Apple has a host of ARM-based prototypes, including an iMac, Mac mini and 13-inch notebooks with quad-core processors. The credibility of the source is questionable but the transition to ARM processors is not a big surprise. Apple has done something similar when they transitioned from IBM based processors to Intel based processors. This allowed the new devices to have vastly improved performance, run Windows and ultimately, boosted sales.
ARM-based processors are now favoured as they use less power and produce less heat while still retaining a high level of performance, so a transition is not a step backward. However, releasing the ARM-based devices now will result in unnecessary competition with their other current products. Hence, it is all about timing for Apple now to make the most of the new technology while keeping their current sales up.
