“If you see a Mac user this week with a barely concealed smile on their face, they’re sure to have heard about the long-awaited big news at Apple’s recent World Wide Developers Conference,” writes Chris White for ComputerWorld New Zealand.
“Apple has ensured that the 2GHz [G5] processors will never starve by placing them on independent 1GHz processor buses. Apple claims that this provides an aggregate bandwidth of 16Mb/second [sic. 16 GBps is the correct spec] and means that RAM is now the bottleneck on the performance of the machine. Sitting on the other end of that bus will be up to 8GB of DDR400 RAM – that’s right, 8GB. Now that there’s a 64-bit chip under the hood, applications can directly access more than the 32-bit maximum of 4GB. While very few have a need to do so currently, it is inevitable that now that the capability is available, applications, especially media editing applications, will be written to take advantage of the increased RAM ceiling,” White reports. “In addition to these upgrades, you will find fast serial ATA hard drives that rival the fastest SCSI drives for performance at a greatly reduced price, an AGP 8x Pro slot supporting a graphics card from either Nvidia or ATI, three 64-bit 133MHz PCI-X slots, three USB 2.0 ports, optical audio in/out, two FireWire 400 ports and a FireWire 800 port. If that isn’t enough, you’ll be pleased to know the machines are also ready for Bluetooth and AirPort Extreme (802.11g).”
White writes, “With the first G4-based computer being released on August 31, 1999, this chip reigned as Apple’s performance king for an extraordinarily long time. So long, in fact, that many professionals who generally upgrade on a two- or three-year cycle have been putting off replacing their old machines in the hope the that G5 would soon be released. Now that it has, I fully expect that the biggest problem Apple is going to have in the coming months is supply.”
