The first Mac to break the 1GHz barrier, the new top performer in the Power Mac G4 family, sports dual 1GHz Power Mac G4 processors with 256Kbytes of level 2 cache and 2Mbytes of DDR (Double Data Rate) SDRAM (Synchronous Dynamic RAM) level 3 cache per processor, Apple said.
The top system, priced at $2,999 in the US (£2,134), also boasts a new Nvidia GeForce4 MX graphics card with 64Mbytes of DDR SDRAM.
Second in line is a 933MHz Power Mac G4 that also comes with 256Kbytes of level 2 cache, 2Mbytes of DDR SDRAM level 2 cache and the new Nvidia graphics card, priced at $2,299 (£1,636).
Apple is also offering a $1,599 (£1,138) 800MHz Power Mac G4 with 256Kbytes of level 2 cache and an ATI Technologies Radeon 7500 graphics card with 32Mbytes of DDR SDRAM.
The dual 1GHz and the 933MHz Power Mac G4s both come with Apple's SuperDrive for CD and DVD burning, while the cheaper 800MHz system comes with CD-RW only.
For RAM and hard disk space, the systems offer 512Mbytes and 80Gbytes; 256Mbytes and 60Gbytes, and 256Mbytes and 40Gbytes, respectively.
