GPU
GPU	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	Built-in video with 2 MB VRAM, expandable to 4 MB; standard VRAM supports 1024 × 768 at 16-bit colour and 1280 × 1024 at 8-bit colour
Memory type
Memory type	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.	16 MB standard, expandable to 512 MB using eight 168-pin DIMM slots

Size and weight detail
Size and weight detail	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).	Apple's Japanese specification lists 156 × 365 × 430 mm and approximately 10 kg; weight varies with installed devices
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.	–
In the box
In the box	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.	Apple lists 17 February 1997 as introduction and projected Canadian availability in March; a distinct verified first-sale date was not established. This is the Macintosh-only model, not the later PC Compatible variant.
