MacBook Pro vs. PowerMac G5

Question

Anybody has tested if MacBook Pro is better than PowerMacG5 (I mean in graphic applications)? And how many times?
PowerBook G4   Mac OS X (10.4.6)  

Answer 1

in real world apps, the G5 does just fine, especially if it is on of the dual core or quad core models. however, in certain processor demanding tasks, the Intel models deliver a significant blow to the G5, and the real world apps will also show significant improvements as the OS and applications are optimized for the Intel architecture. from a pure technical standpoint, the PowerPC architecture is vastly inferior to the Intel Core and soon to be Core2 architecture.
Apple will of course continue to support the PowerPC for a couple of years, but there is absolutely no question that Apple is going forward with its Intel migration and will be dedicating all of its hardware and software to Intel, for at least the next 5 to 7 years, anyways (my personal guess).
Right now, the Mini, iMac, and MacBook(pro) machines are blowing away the PowerMac platforms, when you think of it in terms of price / performance ratio. IF you think of it in terms of $4k for a reasonably equipped quad core G5 (probably the best value in terms of processing power of the G5 line) versus $4k in Dual Core Minis, the Minis will greatly exceed the processing power of the qc G5. If you were running a distributed processing program, this is great. If you are running an application, such as Logic Pro or Final Cut Studio that allows for distributed processing, then this MAY also be great. If you are running an app that needs a fast host machine, the advantage might no be apparent to you.
Since the G5 is Apple's workstation class machine, the only real fair analysis is to compare it with Apple's upcoming workstation class Intel machine rather than budget, integrated, and mobile platforms. Rumors have that machine called the Mac Pro. Rumors also hint that it will have dual Intel Core 2 Duos in the 2 something to 3 something clock range. What does this mean in terms of processing power? I'm not sure but I'm confident that it is at least double, but would not be suprised if it was quadruple, depending on which chip exactly it is and looking at other preliminary performance test done with Intel vs AMD server chips.
Much of this speed advantage is not only the architecture itself, but also the fact that Apple can now tap into a "mainstream" processor line and deploy current technology (which seems to change every 6 to 8 months or so) rather than rolling out PowerPC upgrades every couple of years. PowerPC is probably also at the end of its upgradeability and scalability, something that forced Apple's hand in moving to a new architecture, because even Apple users can only be so forgiving when having to compare spec across platforms.
