Storage
Storage	160 GB to 250 GB (better)	2 GB
CPU
CPU	Two physical PowerPC G5 processors at 2, 2.3 or 2.7 GHz, each with 512 KB L2 cache and no L3 cache. Front-side bus per processor is 1, 1.15 or 1.35 GHz. The dual 2.7 GHz model uses liquid cooling.	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	Dual 2 and 2.3 GHz: ATI Radeon 9600 with 128 MB DDR and two single-link DVI outputs. Dual 2.7 GHz: ATI Radeon 9650 with 256 MB GDDR3, one single-link and one dual-link DVI output. Optional NVIDIA GeForce 6800 Ultra DDL with 256 MB has two dual-link DVI outputs and occupies the adjacent PCI slot.	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	Stock 512 MB PC3200 DDR400, installed in matched pairs. Dual 2 GHz has four DIMM slots and a 4 GB maximum. Dual 2.3 and 2.7 GHz have eight slots and an 8 GB maximum. Configuration rows keep the stock drives 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 160 GB on dual 2 GHz and 250 GB on dual 2.3/2.7 GHz, all 7200 rpm Serial ATA. Two internal drive bays; optional 250 or 400 GB drives, including two 400 GB drives. One optical bay with 16x SuperDrive supporting DVD±R and up to 4x dual-layer DVD+R recording.	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. Dual 2 GHz has three 64-bit 33 MHz PCI slots. Dual 2.3 and 2.7 GHz have PCI-X: two 100 MHz slots and one 133 MHz slot.	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	The exact maker sheet labels height as 47.5 cm, width 20.6 cm and depth 51.1 cm. Earlier G5 sheets label height/depth in the opposite order; main dimensions are omitted because those published axes conflict. Maker reference weight is 20.2 kg and 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	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.	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.

In the box
In the box	Mac OS X Tiger and iLife ’05. Apple’s 27 April 2005 launch says these models are available “this week”; first sale is kept at April precision rather than treating the announcement as a confirmed delivery day. The older single 1.8 GHz model retained in the launch range is represented separately as Late 2004.	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.
