Below you will find performance results for
most of the currently shipping machines, and some from previous
generations. This will, hopefully, give you an feel for the
relative performances of these machines when running OS X.
We will be adding new machines on an on-going basis ... so
check back once in a while. If you are interested in how these
machines will perform when running OS 9, we have those
New machines added to the list below include
all the new dual processor Towers and the 800 MHz eMac.
It should be noted that, although all the machines
below were running a version of OS X, not all were running
10.2, or Jaguar. However the scores below are relative ones
so we are fairly confident that most of the performance relationships
should hold up, despite the change in OS system version. There
may be some variations that we have not completely considered
... so travel with care.
"Real World" Tests
tests below are from our suite of real world application tests.
These tests feature a diverse selection of applications commonly
used by the Mac community. The test suite was designed to
render an accurate and well rounded picture of a machine's
performance. All of the tests below, except for the game tests,
were timed with a stopwatch. The times were then converted
to percentages, relative to the Power Mac Dual G4/1GHz, which
is set to 100%. For all scores, higher numbers are better.
The copy folder test not only stresses drive
performance but also takes advantage of faster processing
capability & caching schemes
In the single file test the the processor
& caching capability of the machine is less of a factor
Drive performance appears to be the prime
Only those machines with CD burning capability
could be tested. No surprise here. Machines with the SuperDrive
s burn CDs slower
The test above creates and destroys 1,000 windows,
indicating on screen graphics performance. See the Let1kWindowsBloom
site for more info.

This test takes place in a large AppleWorks
document. Here you see certain machines, such as the G4 iMac,
turning in lower scores that slower clocked machines, such
as the PowerBook G4/667. This is due to the lack of a L3
backside cache in the poorer performing machines
Jaguar's new File Search function relies on
both processor and drive performance
Number Crunching & Rendering Tests
A Ripple Effect

program has been highly tuned to take advantage of the G4
and is precisely the type of work that the G4 was made for.
It will also gobble up whatever processing capability is present.
This is a good test for assessing the fundamental processing
potential of each machine. Really highlights the processing
advantage of a dual processor machine, and the G4 processor.

movies to DV allows you to import them into iMovie. Dual processors
CD-ROM drive speed and CPU processing power
are the factors influencing the scores above. Our assumption
is that the CD drive speed is the bottleneck in the top of
the line Power Macs above. The top four machines have the
SuperDrive wihich max out at a read speed of 24X.
As you can see by the consistancy of the numbers,
this is straight processing work
QuickTime DV Encode and MP3 Encode performed
at the same time. Dual Processor machines rule the day
MP3 Encode, AppleWorks search & replace
and folder copy are all carried out at the same time. If you
need to have your computer carry out multiple activities at
the same time, a dual processor machine will definately get
you there faster.
QuickTime Sorenson encode and Fractal render
are both carried out at the same time. The Dual processor
1.25 GHz Power Mac is almost twice as fast as the single processor
is tuned to take advantage of the processor. Indeed, when
run on a dual processor machine, you will see Giants fly
ahead of the same game running on a single processor machine.
It also helps to have a better graphics card. The 1.25
GHz machine turned in 55 frames per second
