It's easy to forget that Apple snapped up P.A. Semi for a song way back when, but now that we're just days, hours and seconds away from Apple's expected tablet reveal, a new wave of processor-related conjecture is hitting the fan. Richard Doherty, director of technology consulting firm Envisioneering Group, has come forward with some exceedingly detailed rumors on said tablet, a touchscreen MacBook and an OS X-based unicorn that lives in the cloud. As the story goes, Apple's pickup of P.A. Semi was primarily an effort to acquire a huge pool of engineering talent to use for its own internal designs, and now Doherty is saying that "before the year is out, Apple will have the most powerful, lowest-cost SoC in the industry." According to him, there's nothing from "ARM licensees or Intel that could challenge the power-per-watt, the power-per-buck, the power-per-cubic-millimeter of size," and he anticipates that four new products are in the pipeline from Cupertino. Need details? How's about a touchscreen iMac, an "iPod touch on steroids" with a 5-inch display, and "two different versions of media pads in the 7- to 9-inch (screen size) area." Alright Dick, you just put your reputation on the line -- here's hoping you've got your story straight.Update: Looks like UBS Investment Research has been hearing something similar. According to it, the forthcoming tablet "will be powered by a processor designed by P.A. Semi and built by Samsung."
