Apple shifts to Intel: what is all the fuss about? | The Register — Here is an excellent analysis of the Apple Mac-Intel platform shift. I’ve noticed that the many PPC advocates seem to be in denial right up until the Jobs announcement. One fellow (a Mac online columnsit) even says that the announcment MUST be about Intel second sourcing the PowerPC chip! That one had me rolling in the aisle.

First, understand the key fact: a Mac built out of an Intel CPU and Intel system logic will be no more a PC than a Mac is today. Two things make a Mac: the operating system and the hardware design. It is not, for the vast majority of users, what kind of processor it contains.

Most of the components that go into that hardware are already coming straight out of the wider Wintel world, and have been since Apple began ditching proprietary specifications like NuBus and ADB, and expensive standards like SCSI, in favour of USB, Firewire, UItra ATA, Serial ATA, PCI and AGP.

Mac hardware today differs from PCs solely in the CPU, system logic and the motherboard they sit on. You can argue that PowerPC is a ‘better’ chip than x86 equivalents, but it’s difficult to demonstrate a clear, real-world advantage between the two platforms. Some benchmarks show the Mac’s superiority, others don’t. The G5-class PowerPC 970 certainly hasn’t retained the low-power benefit of the old G4 and looks no closer to notebook-suitability now than it did when it was launched.
