The new G5 models use IBM's PowerPC 970 chip, which offers a 64-bit architecture and other enhancements over the previous G4 chips, manufactured by Motorola. Apple says the new G5s are built for full symmetric multiprocessing can run 32-bit applications with "no problem." They offer up to 1 GHz frontside bus, support for up to 8 GB DDR RAM (up to 400 MHz 128-bit wide DDR) and 8x AGP graphics. Apple says the new machines offer 12 times the bandwidth of the previous G4 models (8 GB per second), with 6.4 GB per second memory bandwidth. It also incorporates 133 MHz PCI-X slots with 2 GB per second bandwidth.
Other features include:
- Serial ATA with 1.5 GB per second bandwidth;
- One FireWire 800 port;
- Two FireWire 400 ports;
- Four USB 2.0 ports (including ports on the keyboard);

The new models are available in three configurations with the following specs (in addition to those listed above):
- Single 1.6 GHz G5 with 256 MB RAM, 80 GB hard drive, 800 MHz front-side bus, 333 MHz dual-channel 128-bit DDR memory, four DIMM slots (up to 4 GB RAM), three PCI slots (64-bit, 33 MHz), Nvidia GeForce FX 5200 Ultra-64 MB DDR;
- Single 1.8 GHz G5 with 512 MB RAM, 160 GB hard drive, eight DIMM slots for up to 8 GB memory, three PCI-X slots (one 64-bit 133 MHz, two 64-bit 100 MHz), Nvidia GeForce FX 5200 Ultra-64MB DDR;
- Dual 2.0 GHz G5 with 512 MB RAM, dual independent 1 GHz front-side buses, 160 GB hard drive, three PCI-X slots (one 64-bit, 133 MHz, two 64-bit 100 MHz), eight DIMM slots for up to 8 GB RAM, Radeon 9600 Pro with 64 MB DDR RAM.
The 1.6 GHz model sells for $1,999. The 1.8 GHz model sells for $2,399. And the dual 2.0 GHz model sells for $2,999. Apple also says it expects 3 GHz models to be available within a year. For more information, visit http://www.apple.com.
