Hello everyone

I was wondering what exactly are the differences between a MAC and PC processor? (this is not a Versus question) I just want to know how they differ from one another in performance and how they both work. what makes a mac a mac and a pc a pc? also how come a mac can emulate a pc but not the other way around?

thanks

I think its hard to answer that question. I think I'd just consider the mac more like a big american V8 - less revs but more work per rev and the Intel/PC to be more like an import engine...more revs on a smaller engine so more revs needed to do the work.

Also there is something called PearPC which is still in Alpha stages that can emulate a G3/G4 and can run OSX but it is very slow. Still runs though...

The current day Macs use RISC processors while the PC's use CISC processors. Check this site out for a more information about the two processor types.

Here, read this http://arstechnica.com/articles/paedia/cpu/ppc970.ars/1 over a few times and if you still have questions, take a look around the Arstechnica site and I'm sure they have the answer.

There is no reason why a PC could not emulate a Mac...ie run mac software. If you check with google you will find a number of emulators, here (http://www.emulators.com/) for example.

As to the practical difference between a CISC (PC) and RISC (Mac) processor? Using both a Mac and a PC on aregular basis I find that the clock speed of a PC CISC processor has to be roughly 2-3 times faster than a Mac RISC processor to provide equal speed performance at the user level - depends on the application of course.

The biggest difference for me between Mac and PC is the software - Mac OS vs Windows. All versions of Windows I have ever used crash on a regular basis, Mac OS 9 in comparison crahed very little - Mac OS X has never crashed in the last two years various members of my family have used it...in fact I had to explain to my daugher what I meant with the "Computer crashing" when I askled her the question about her eMac.
