im sure with alot of time... they could code a bios interface that tricks the pc into thinking its a normal chip... and when sending requests it gets translated.... would prob slow it down a bit.... but at that speed.
a 5% drop in speed is noting
PowerPC is a RISC chip. The Pentium (and I believe the DUOs) are CISC (with some RISC aspects). Huge difference.
When Apple was running OSX on PowerPC, and then emulated Windows using VirtualPC it was really slow. The reason (as I had read) being one of the chips is little endian and the other is big endian. Virtual PC had to take instructions, reverse them and then send it to the PowerPC. Very slow.
Now, I believe there would be absolutely no reason why Apple couldn't release OSX for the Power 6 platform. They were already on it for 4-5+ years. Maybe Apple could release high end servers running Power 6, and keep using DUOs for consumers.
