CPU
CPU	Single 1.6 or 1.8 GHz, or dual 2 GHz PowerPC G5 processors; Apple identifies IBM fabrication. Each physical processor has 512 KB L2 cache. Front-side bus per processor is 800 MHz, 900 MHz or 1 GHz respectively. A dual 1.8 GHz configuration was added on 18 November 2003, available immediately; it remains part of this generation.	One 166 MHz PowerPC 604e with integrated floating-point unit, 64 KB level-one cache, 50 MHz processor bus and 256 KB level-two cache; processor is on a removable card
GPU
GPU	Stock 1.6 and 1.8 GHz: NVIDIA GeForce FX 5200 Ultra with 64 MB DDR. Stock dual 2 GHz: ATI Radeon 9600 Pro with 64 MB DDR. November dual 1.8 GHz: GeForce FX 5200 Ultra 64 MB. Optional ATI Radeon 9800 Pro 128 MB.	Built-in video with 2 MB VRAM, expandable to 4 MB. Exact support table gives 24-bit colour through 832 × 624, 16-bit at 1024 × 768 and 1152 × 870, and 8-bit at 1280 × 1024 with standard VRAM; 4 MB permits 24-bit through 1152 × 870 and 16-bit at 1280 × 1024
Memory type
Memory type	Single 1.6 GHz: 256 MB DDR333, four DIMM slots, maximum 4 GB. Single 1.8 GHz and dual 2 GHz: 512 MB DDR400, eight slots, maximum 8 GB. November dual 1.8 GHz also has 512 MB DDR400 and an 8 GB maximum. DIMMs are installed in matched pairs. Each configuration retains its stock drive and graphics at base and maximum memory.	16 MB standard and 512 MB supported maximum using eight 168-pin 64-bit 5 V DIMM sockets, 70 ns or faster. EDO modules are treated as fast-page memory by the controller; matching DIMMs in corresponding sockets enable interleaving. Apple says 128 MB DIMMs can be used but were not tested. 4 MB ROM. Shared Service Source specifies 60 ns or faster EDO DIMMs for the 7300 series, while the exact Japanese page and English support specify 70 ns or faster; this difference remains explicit.
Storage type
Storage type	Stock 80 GB on the single 1.6 GHz; 160 GB on the single 1.8 GHz, dual 2 GHz and November dual 1.8 GHz. 7200 rpm Serial ATA drives; two internal bays with 150 MB/s interfaces. One optical bay with 4x DVD-R SuperDrive; optional Combo drive and 80, 160 or 250 GB drives.	2 GB internal Fast SCSI hard disk, manual-inject 1.44 MB Apple SuperDrive floppy and AppleCD 1800i 12× CD-ROM. One additional internal 3.5-inch storage bay; internal SCSI transfers up to 10 MB/s
Expansion slots
Expansion slots	AGP 8x Pro graphics slot. Single 1.6 GHz has three 64-bit 33 MHz PCI slots; faster original models and the November dual 1.8 GHz have PCI-X slots, two at 100 MHz and one at 133 MHz.	Three PCI 2.0 slots; processor on a replaceable card. The 7300 does not include the analogue AV module supplied with the 7500 and 7600

Size and weight detail
Size and weight detail	Published height 51.1 cm, width 20.6 cm, depth 47.5 cm; 17.8 kg reference weight varies with configuration.	Apple’s exact Japanese specification gives 156 mm high, 365 mm wide and 430 mm deep, 10 kg; weight varies with installed devices. Shared Service Source gives the corresponding 22 lb (9.97 kg).
Power supply
Power supply	–	Exact Japanese maker page specifies 100–130/220–270 V AC, single phase, manually switched, 50–60 Hz, and claims 298 W continuous/453 W peak excluding monitor. Shared Service Source instead specifies automatically configured 100–240 V AC and 150 W maximum, while English support lists 150 W and 100–130/200–270 V. These unresolved differences are retained without an unqualified consumption figure.
Materials
Materials	Aluminium enclosure with separate thermal zones.	–
In the box
In the box	Original models shipped with Mac OS X Jaguar; the November dual 1.8 GHz announcement includes Panther. Apple’s 18 August 2003 shipping release confirms immediate availability of the single-processor models; the original dual 2 GHz was due later that month.	Exact Apple support lists 13 February 1997 as introduction and says this model was not sold in the US. Contemporary PC Watch retail rankings report Japanese sales beginning March 1997; first worldwide sale month/day remains unconfirmed, so release is kept at 1997 year precision.
