how do the power mac dual processors. say the dual 1.42 model compare with the powerbook in terms of speed when running application final cut pro, imovies, idvd, cinema tools???

how big is the speed difference gap??

It's huge. The Power Mac is two to three times faster than the PowerBook for processor-intensive tasks.

PowerBook 1 GHz is about the same in processing speed (Photoshop) as PowerMac 500 MHz.

That's not true.

..less or more ?

A 1-gigahertz PowerBook is much faster than a 500-megahertz Power Mac.

.thank god for that..

yup. I have a 733MHz with 1.5GB RAM, and my new 17" is faster.

As stated by sean, the speed difference between a Dual 1Ghz+ PowerMac and a single 1Ghz 17" PowerBook is massive, escp. in majorly intensive tasks such as the ones you mentioned. But it's not exactly fair to expect a notebook computer to perform the same as a desktop w/ such cooling and mobile limitations...for being a notebook the 17" PB holds its own extremely well.

That is such BS. It's close to twice as fast for audio (logic audio is what I use), and easily twice as fast for everything else. I know this from every day experience.

anyway, here are some benchmarks.

Be aware that I use FCP 3 and it works fine, (though I have modified the RT enablers). I have no desire to have a powermac. I don't even consider it an option. Powerbooks are powerful enough that, the way I see it, apple only makes laptops.

That's not to say that powermacs are not much more powerful. I'm just not hurting for power at the moment at all. And, yes, I do a TON of rendering with AE, FCP and Cinema 4DXL. Actually, the only one that takes a long time is Cinema 4D, but OS X allows me to work on anything else while it's rendering without an overly noticable speed hit.

I haven't used a new PowerBook in a while, but my dual 867 PowerMac is MUCH faster than my PowerBook 800. Don't have any hard numbers for you. I'd expect the comparison between a dual 1GHz+ and a 1GHz PowerBook would be roughly the same.
