| | I do not believe that any existing X86 processor, or any which is expected to be released in the next 12 months, is capable of emulating PPC code at a speed equivalent to direct execution on a 1.25 GHz G4, no matter what approach is taken to it (such as binary recompilation). | | | The latest news is that Intel's software x86 emulator on Itanium runs several times faster than the hardware emulator in the said Itanium. | | | Their PPC apps would not work on the X86 Mac, and many of them would not have been ported, and there'd be no replacements available. |
