The new Power Mac G4 is up to twice as fast as the fastest Pentium III-based PCs 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 doorWith 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 youve completed your projects shooting those big files across the network is a snap because every new Power Mac G4 comes with 10100BASE-T Ethernet built inThis means that when you buy it it is ready to go to get set up to your local cable internet providerThe secret of the G4s revolutionary performance is its aptly named Velocity Engine Its 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 its the 128-bit vector processing technology used in scientific supercomputersexcept 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 processorsThe new G4s are proven to be faster that pentium 3s Using six of Intels tests the 450MHz G4 was on average more than two and a half times as fast as the 600MHz Pentium III 265 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
