Clock Speed Comparison From MAC to PC

Anyone have some sort of conversion table that will take the clock speed of a MAC and compare it to PC clock speed.

i.e. MAC G4 1.25Mhz = PC ?Mhz

seriously, clock speed is not where it's at, even more so when you are crossing platforms like that. The only way to know which one is faster is to run the same app you need it for on both platforms and time them.

Not only do Macs have different CPUs than PCs, they are different machine architectures. Apple keeps the Mac proprietary, while the PC architecture is public. They use different chipsets, I/O connectors and the way the machine represents things internally is different. For example memory on some macs is arranged backwards compared to PCs, meaning that chunks of a number are addressed and stored differently, this gives certain advantages and disadvantages. Also, since the Mac is proprietary, apple can do things to tweak performance that can't be done on a PC, not that I know of specific.

What are you talking about? The poster obviously knows that megahertz doesn't necessarily mean speed, or he wouldn't be asking the question.

i realize the poster doesnt necessarly believe the mhz myth, and i didnt mean to refer him as such even tho it seems like i did. it does bring about the question of who still believes in it(certainly not anybody on anandtech).

his general question does guide one to that area of thought however.

add a 0 to to and then multiply it by pi/e and then add 69 and you have the PC clock

i thought this board was filled with CS/CE people

eh what are you talking about?
All the new world macs use PCI/AGP/IDE/SCSI/SDRAM/etc standards. As far as "memory being arragned different" - if you're talking about big/little endian-ness, thats completly arbitrary and doesnt even matter.

For the past decade mac has been based on Risc architecture and there is no direct way to translate mhz like that. It's never been a linear relationship...

IMO, Macs are becoming more like PCs everyday. Which is good as long as Mac stays a Mac. The day I see Windows ver XXX on a mac I will give up computers as a hobby and career. I like PCs as PCs and like Macs as Macs. I only wish the freaking game programers would make simultanious releases on both platforms.

Man, a 1.25 Mhz Mac is probly at least as fast as a 6 or 7 Megahertz PC, as those 8086's have a very low IPC :p
