Mac OS X Speed of Apple Intel dev systems

Apple made a HUGE decision on using Intel CPUs for the next generation Macs.

According to the earlier development system test, the Mac OS X on Intel dev system boots up in 10 seconds, compared to more than 1 minute on my Power Mac G5 dual 2.5GHz.

What impressed me most is the performance of Rosetta: dynamic binary translator to run PowerPC-native programs on Intel hardware. It is said that on Intel machines, native PowerPC programs run at about 60%-70% of the orginal speed. I think the basic design of Rosetta is closest to PearPC, which emulates a PowerPC Architecture on Intel platform.

If you take a look at the hardware in the Apple Intel dev system, you won’t notice much of the difference between the Apple system and a normal PC. Although the bundled Mac OS X won’t run on other Intel hardwares than the dev system, it might be possible to home-build an identical Intel-based system. However, I guess Apple will let Mac OS X detect an unique component in their systems, so as to prevent the DIY hack.

We’ll soon see, in less than 1 year now.
