Mac Reference Desk: The April
2002 PowerBook G4/667 and G4/800
On April 29th, between expos and with little fanfare, Apple
introduced the latest revision of the PowerBook line. The new
'Books sport either a G4/667 or G4/800 processor, but unlike
predecessors, the latest PowerBooks also sport a 1 MB level
3 cache in addition to the 256K "on chip" (aka level
2) cache found on the December 2001 PowerBooks. This cache runs
at an unimpressive sounding 4:1 ratio, but uses DDR SRAM to
significantly improve performance.
April 2002 PowerBooks also feature an improved graphics system,
using ATI's 32 MB
Mobility Radeon 7500. The December 2001 PowerBooks used
ATI's 16 MB Mobility
Radeon GPU. Games should be pleased with the performance
Completely new to this generation PowerBook
is the presence of a DVI port. This allows you to connect
to a standard VGA monitor with the included adapter or to
any of Apple's flat panel displays. To connect to the latter,
you will need to buy a DVI to ADC adapter. Dr.
Bott and Apple both
sell these adapters for around $150. Perhaps as an acknowledgement
that it has outlived its usefulness, Apple has done away with
the infrared port. Currently supported only as a "technology
is likely seen as infrared's replacement. Below, we provide
you with a quick overview of the most significant changes
