There is reason to believe that Apple would talk to Intel and may have some news to announce soon, but there's no truth anywhere in the assumptions most of these "journalists" are making about Apple's motivation.
First, if you compare equivalent systems, Apple's products are cheaper than Dell's. Try it for yourself, go to Apple's on line store and pick a standard configuration laptop, desktop, or server and then build the nearest equivalent you can using Dell's on-line pricing. What you'll find may surprise you: Dell's low end products are cheaper, but by the time you add components to gain comparability they cost more -and that's true right across the line with Apple's high-end product a good $1,500 less than Dell's nearest comparable workstation.
Second, when you compare performance, it's important to remember that the operating system and applications environment count too. Mac OS X does a lot more than Windows/XP, but needs more system resources to do it. If, therefore, you want to make a reasonable guess about the relative performance of Mac OS X and Windows XP on the same 3.5Ghz P4 box, you need to first level the software playing field. That's relatively easy: just look at grid-style super computers where everybody uses whatever Unix is optimal for their hardware and runs the same applications. Compare, for example, performance at the Virginia Tech machine made up from Apple's X-serves to the NCSA machine in Illinois made up from Dual Xeon Dell servers and what you find is that the Apple boxes contribute 30% more bang per box than the Dells do.
There's a double bottom line here: Apples to Apples, Macs are cheaper than PCs, and their processors are faster too.
So why would Apple be talking to Intel? Assuming the conversation has been about primary system CPUs, I can think of three possible reasons:
Oh and the right answer? For the record, my belief is that Apple's best route out of its strategic CPU dilemma is UltraSPARC. I haven't seen BSD on Niagara (Sun's 8-core, 32-thread, 65-watt SMP chip), but if the Solaris systems now in lab and user test are any indication, this could be a winner. Individual processes run more slowly on Niagara than on, say, the UltraSPARC IV, but more of them run in parallel and the power benefit should be enormously attractive to Apple -and the software barrier to SPARC is much lower than it is to either Itanium or Cell.
