Power Mac G4 Essay, Research Paper
With
its Pentium-crushing speed and new design, the Power Mac G4 picks up where the
old Macintosh (G3) left off. Its enclosure is now highly polished silver and
graphite, yet it still offers easy access to every internal component through
its swing-open side door. With PowerPC G4 with Velocity Engine, the computer
speeds up to 450MHz, one megabyte of backside level-2 cache running at half the
processor speed, and a 100MHz system bus supporting up to
800-megabytes-per-second data throughput, the Power Mac G4 delivers high
performance. And when you?ve completed your projects, shooting those big files
across the network is a snap, because every new Power Mac G4 comes with
10/100BASE-T Ethernet built in.This means that when you buy it, it is ready to
go to get set up to your local cable internet provider. The secret of the G4?s
revolutionary performance is its aptly named Velocity Engine. It?s the heart
of a supercomputer miniaturized onto a sliver of silicon. The Velocity Engine
can process data in 128-bit chunks, instead of the smaller 32-bit or 64-bit
chunks used in traditional processors (it?s the 128-bit vector processing
technology used in scientific supercomputers?except that they have added 162
new instructions to speed up computations). In addition, it can perform four (in
some cases eight) 32-bit floating-point calculations in a single cycle, which is
two to four times faster than traditional processors. The new G4?s are proven
to be faster that pentium 3?s. Using six of Intel?s tests, the 450MHz G4
was, on average, more than two and a half times as fast as the 600MHz Pentium
III (2.65 times, to be exact). These benchmark advantages translate directly
into real-world advantages. For example, typical Photoshop tasks run 187% faster
on the Power Mac G4 as they do on the fastest PentiumIII-based PCs, with
specific Photoshop filters running up to four times faster. Compressing
QuickTime files is also much faster. Other Hardwear Monitor This is the ultimate
companion to the Power Mac G4: the Apple Cinema Display. Its 22-inch diagonal
