This is our first look at the performance of
the new PowerBooks from Apple. This time we pit the last vesion's
top of the line machine (the 667 MHz) to the low-end machine
of the current crop of PowerBooks (coincidently also clocked
in at 667 MHz)
Though both machines are clocked at the same
speed, other technical differences make the new 667 MHz PowerBook
faster over-all.
The main difference between the old and new
667 MHz PowerBooks, is the addition of a L3 (backside cache)
to the later. This cache on the newer PowerBook weighs in
at 1 MB. Though the speed rating of the cache (167 MHz) won't
win any speed trials, its addition significantly boosts performance
in such areas as drive performance, desktop redraws, and any
other activity where the processor would have to take the
slow, circuitous route back to main memory, to find the tidbits
of data that can now be found in the faster cache of the upgraded
PowerBook. The cache is also
DDR memory which in theory should double its rated throughput
speed.

In our Folder Copy Test, the new PowerBook was
73% faster
The new PowerBook Booted 37% faster
Window redraws were 30% faster
Search and Replace 26% faster
Video Encoding 15% faster
In our game testing (Quake III) the new machine
turned in 59% better performance
That is the second significant performance change
in the new Model PowerBook. It has a better graphics card
with twice the amount of memory. This makes for significantly
better fps (frames per second), and hence better game play.
If you are a professional, thinking that a laptop
can take the place of a standard desktop machine, we also
post results below for the top of the line Dual Gigahertz
Power Mac ... kind of a reality check!
Notes on the performance numbers below:
We are presenting you with the raw data this
time around. This is not ideal, but we have limited time at
the moment as we are focusing most of our time on site redesigns.
We hope to bring you graphs and further performance comparisons
of the this machine, as well as others, when time allows.
In the meantime, the numbers below are in seconds, and lower
numbers means better performance. The exception is the Giants
game results , which are in Frames Per Second. Here higher
numbers are better.
