MAC on PC?

I'd like to clarify that. What it is, really, is that the x86 pipeline, the way the processor handles data, contains 21 (I believe) "stages", each of which the data must complete before it can reach its destination. The PPC processor contains 7. (Again, I believe. If someone knows, please tell me the actual numbers.) Due to this, even though the processor runs at a slower clock speed (MHz), the data needs only to complete 7 stages, and therefore can be processed faster in some instances even though it takes it longer to complete each stage. This is especially true when a branch is reached in the code -- an if/then statement or some other piece of code that relies on previous data to execute. The first data must go through, and the pipeline cannot even BEGIN to load more data until the first data is all the way through. That yields 21 unused cycles per branch, whereas on the PPC, it's only 7 unused cycled per branch. The G5 works even faster, but I'm not quite up to date on it yet, so I won't risk trying to explain it and ending up saying something wrong.[/quote]
not all ppc's are 7 stages. the g3 (ppc750), i believe, is 4 stages; for the g5 (ppc970), IBM tripled the number of stages, which would be 12. the g4 (ppc75xx) has 7 stages. according to apple's old "mhz myth" video (which, no doubt, is where you based your info), which listed 20 stages for the P4, 10 stages for the itanium, and 14 stages for the ultrasparc III.

Ah, thanks.

apple's old "mhz myth" video [/quote][/quote]Ooh sounds like fun. Any idea where I can get a copy of it?

after some searching, i saw that apple canada's site still has it. you can watch it here. this video was there in late 2001.

Oh man I thought it was some 80's video...

how many of you windows users have ever gotton over a month of uptime on your computer or say over a year while running SuSE 8.2 pro i had a max uptime of 421 days

instead of making it look pretty they should try to make it stable

also spinning windows wouldn't be all that hard to program so its not a groundbreaking acomplishment

as far as some arguments i've seen that macs aren't as fast as pcs,
read up on the new G5 which is fast i'm talking stuff like opening 700, 72 dpi 8x10in pics in 3 seconds

the new 64 bit pc chips need programs written for them, programs written for 32 bit will run in a slow emulation mode

The new G5's were made from the beginning to run 64 bit apps alongside 32 bit apps

also did i mention windows stability, its just crap! and don't tell me different untill you run your computer for 421 days strait (the only reason you have to restart linux is to install a new kernel or add new internal hardware)

and virises? there are NO virises out for macs NONE.

its built on unix which is the most stable OS to date.

for those of you that might use the argument that more ppl run windows you may also note that there are more roachs than humans , more fords than lamborgini's

Dude, there's no virus's for Mac's because damn near no one uses Mac's. Well, thats probably an exaggeration, but you know what I mean.

Look at all the ones beginning with "Mac".

it also helps that windows has about as many holes in it as swiss cheese

and i kinow there are virises out for older mac OS's but there are none out that effect OS X

Not YET. Just give it time.

do you know HOW fricken hard it would be to write a virus to take down a unix/linux comp? (again i'm not talking about old unix systems)

What's your point? It's already happened before, as was pointed out to you, what makes you think it wouldn't happen again?

<---- agrees with Soth.

The advantage unix based systems have is the security levels. A virus would have to 1: exploit a program to execute at this user level. It could then delete personal documents, spread itself (to other sytems, not users), but not much else. It would then need another exploit if it were to break the rest of the system and do further damage.

Of course there are ways to skip the middle step, but in a properly set up unix machine they are very few.

<-- Agrees with Soth too.
