CPU
CPU	Dual 867 MHz, dual 1 GHz or dual 1.25 GHz PowerPC G4 processors; each physical processor has 256 KB on-chip L2 cache. 867 MHz and 1 GHz have 1 MB DDR SRAM L3 per processor; 1.25 GHz has 2 MB. System bus 133 MHz on dual 867, 167 MHz on dual 1/1.25 GHz. CPU count describes physical processors; supplier is not inferred.	120 MHz PowerPC 603e with integrated floating-point unit, 32 KB L1 cache and standard 256 KB L2 cache. Exact English support lists a 64-bit processor data path at 40 MHz; this is not a claim that every memory or I/O bus is 64-bit.
GPU
GPU	Dual 867 MHz: NVIDIA GeForce4 MX 32 MB DDR. Dual 1/1.25 GHz: ATI Radeon 9000 Pro 64 MB DDR. Optional NVIDIA GeForce4 Ti 128 MB; independent CTO options are not expanded into unsupported stock combinations.	1 MB built-in DRAM framebuffer, independent of system RAM. DB-15 monitor output supports 640 × 480 with 16-bit colour or 800 × 600 and 832 × 624 with 8-bit colour. Exact English support states video input is not supported at 832 × 624.
Memory type
Memory type	Dual 867 MHz: 256 MB PC2100 DDR SDRAM at 266 MHz. Dual 1 GHz: 256 MB PC2700 DDR at 333 MHz; dual 1.25 GHz: 512 MB PC2700. Four DIMM slots support up to 2 GB. Configurations preserve stock processor/drive/graphics ties at base and maximum memory.	16 MB standard, expandable to 64 MB using two 72-pin noncomposite SIMM slots with 80 ns or faster DRAM. No RAM soldered on the board in exact English support; SIMMs can be installed individually. Original Japanese accessory list also advertises an 8 MB 70 ns memory kit.
Storage type
Storage type	60/80/120 GB 7200 rpm Ultra ATA/100 stock drives respectively. Dual 867 MHz has Combo DVD-ROM/CD-RW (CD-R 16x); faster models SuperDrive (DVD-R 2x, CD-R 8x). Four hard-drive bays support two ATA/100 and two ATA/66 drives, or up to four SCSI drives with a separately sold PCI card. Two optical bays, one occupied; optional second Combo drive. Maker optional storage choices remain in details rather than assumed CPU cross-pairs.	1.2 GB internal IDE hard drive, Apple SuperDrive 1.44 MB floppy and 4× AppleCD 600i CD-ROM drive in the exact Japanese factory configuration.
Expansion slots
Expansion slots	Four open full-length 64-bit 33 MHz PCI slots and dedicated AGP 4x graphics slot.	LC-compatible 68030 processor-direct expansion slot, communications slot for optional Ethernet or modem, optional video-input card and TV tuner connector. No PCI. Optional Apple TV/FM Radio System requires the Apple Video System; NTSC, PAL and SECAM capture are available with the relevant expansion card.

Size and weight detail
Size and weight detail	Exact maker reference weight 19.1 kg varies with configuration and manufacturing process; height 43.2, width 22.7, depth 46.8 cm. These published dimensions differ slightly from earlier G4 sheets and are retained.	Exact Japanese maker page gives 109.5 × 320 × 419.5 mm (height × width × depth), 8.6 kg for the computer. English support gives 4.3 × 12.6 × 16.5 inches and 19 lb, rounded equivalents. External monitor, keyboard and mouse are excluded.
Power supply
Power supply	100–125 V AC or 200–240 V AC, 50–60 Hz. Maximum current 6.5 A at low voltage or 7.5 A at high voltage; maker publishes no maximum wattage here.	Exact Japanese maker page specifies 82 W maximum excluding the monitor, 100–240 V AC at 50–60 Hz. Exact English support and archived Apple Spec Database instead give 55 W maximum, 110–240 V at 50–60 Hz. Clock battery is described as lithium in the Japanese page and 4.5 V alkaline in the English table. Conflicts remain explicit; no universal operating-consumption headline or inferred battery type.
In the box
In the box	Mac OS X 10.2 Jaguar as default startup system, plus bootable Mac OS 9.2.2; iMovie, iPhoto, iTunes and iDVD for SuperDrive. Maker August 13 release says dual 867/1 GHz available that week, so first sale uses August month precision. Actual dual-1.25 GHz shipping confirmed 18 September. January 2003 FireWire 800 models and June 2003 reissue are separate generations.	KanjiTalk/System 7.5.1 and 4 MB ROM. Apple records introduction on 27 June 1996; PC Watch’s contemporary 2 July retailer survey explicitly reports sale from 27 June, corroborating that date. English maker table states this system was not sold in the US. The 120 MHz Power Macintosh is distinct from the existing 100 MHz Macintosh Performa 6300CD; no unverified official predecessor link is assigned.
