Maybe in recent times things have changed. But I' ve heard they haven' t all that much.
Both yes and no. In 2001 Motorola begun lagging with updates to their G4 cpus and new Macintosh machines as a result begun getting behind their PC counterparts. As power where no longer a selling point Apple had to concentrate on optimising their applications for performance as well as concentrate on quality over pure speed. Which resulted in mac OS X which today is far beyond Windows in quality and features. But at the same time applications dependent on speed such as the latest games and high-end calculation programs lacked. So if it was for good or worse really depends on what you use your computer for: good for the general user, bad for hardcore gamers and scientists.
But with Motorola lagging IBM and Apple in silence teamed up to create a desktop version of IBM' s high end Power4 serverrs
(The kind you can not buy for less then $10.000). The result is the PPC 970, a stripped down Power4 cpu with added SIMD instructions to be compatible with AltiVec in the G4. So what has happened is that Apple and IBM made a high end 64bit CPU used for supercomputers (Like
ASCI White) available and affordable for personal computers and now many people are not quite willing to accept that such a cpu can compete and in for some applications outperform Intels lineup for personal computers.
Most notable those people concentrates on spec benchmarks, numbers that has been twisted back and worth and I can agree there are:
lies, damn lies, and benchmarks, so those should be taken with a fist-full of salt.
The other tests that it has been more quite about, which is real-life tests done using of the shelf
(With the latest patches available to end users) software available for both Windows and Mac OS X. Tests has been done with for example Photoshop 7, Mathematica and Quake 3. The tests has shown that the PowerMac G5 outperforms Dual Xeons 3GHz from a few percent to almost the double depending on the application.
I can not quite understand why people get so obsessed by benchmark numbers, when these real-life tests speaks so laud. Anyone can go to a Apple retail store
(I have) and perform those tests themselves. And if Photoshop renders a poster in half the time, or Quake 3 has a higher frame-rate, then what is there to argue about? So what if the benchmark numbers does not match up?
