At the '99 WWDC (May 10th, 1999) Apple finally released the
much anticipated new generation PowerBook. Currently available
in either 333MHz or 400MHz varieties, Apple has made some
significant changes and, a pleasant surprise, has left a few
things unchanged. See "New,
Removed, Unchanged" sidebar below for a summary.
As is always the case before Apple releases a new machine,
the net was awash with speculation about improvements and
changes to the new PowerBook line. Most everyone agreed that
USB would
replace the serial port, which it did, but hopes of a 100MHz
system bus and FireWire ports were dashed. Apple has continued
its standardization on the crisp  14"
TFT display. Although hopes for an ATI 128 graphics system
didn't pan out, the SGRAM on the ATI RAGE LT Pro has been
bolstered from 4MB to 8MB. While older G3 PowerBooks were
limited to video mirroring, the new 'books can support dual
monitor use, a boon to those of us desperate for screen real
estate. Apple is also using an improved lithium ion battery
which they claim will run for 5 hours, up from 3.5 hours on
older G3 PowerBooks. It is unfortunate that Apple decided
to limit the backside cache on the 333MHz model to 512k. The
cache also operates at a slower 2.5:1 ratio instead of the
faster 2:1 ratio on older PowerBooks. Both of these factors
bring the processor score
on par with the 300MHz PowerBook with its full 1MB backside
cache. The hard drive on the 333MHz PowerBook is an acceptable
4GB and can be bumped up to 10GB for the truly demanding user
Like its earlier incarnations, the new PowerBooks offer great
built in connectivity options. The built in 10/100Base-T Ethernet
connector offers transfer rates up to 100Mbps, handy for plugging
to that high speed office network. For the home user there
is an internal 56k modem with v.90 support. Lastly, there
is the infrared port offering 4Mbps wireless networking. The
two hot-swappable side bays allow you to plug in two batteries
for up to 10 hours use, up from 7 on previous G3 PowerBooks.
This estimate is based on the slightly improved battery and
better power management in OS 8.6. The same bays which host
the CD/DVD drive can also take a Zip or floppy drive. The
floppy drive is not standard on this machine and Apple has
stated that they will not be offering one. You can expect
third parties to fill the gap. Most noteworthy of the changes,
of course is the new slim design, under two inches thick and
5.9lbs, almost 2lbs less than previous G3 PowerBooks. Below
we provide you with benchmark information so you can see how
the new PowerBooks stack up against the old

Below you will find MacBench 5.0 scores comparing the PowerBook
G3/333/512k to several other PowerBook G3's We have formatted
these scores to be relative to the former high end PowerBook
G3/300 which we set at 100%. Original scores are from Apple's
