CPU
CPU	Dual models have one physical dual-core PowerPC G5 at 2 or 2.3 GHz. Quad has two physical dual-core processors at 2.5 GHz, four cores in total. Each core has 1 MB L2 cache. Front-side bus per physical processor is 1, 1.15 or 1.25 GHz respectively. Macworld’s exact Quad review describes its liquid cooling.	300 MHz PowerPC 603e with integrated floating-point unit, 32 KB L1 cache, 512 KB L2 cache and a 64-bit 50 MHz bus. The shared service specifications use the name 603ev; the exact support page and original brochure use 603e.
GPU
GPU	Stock dual-core 2 GHz: NVIDIA GeForce 6600 LE with 128 MB GDDR SDRAM. Dual-core 2.3 GHz and Quad: NVIDIA GeForce 6600 with 256 MB GDDR SDRAM. Optional NVIDIA GeForce 7800 GT 256 MB and Quadro FX 4500 512 MB; the Quadro occupies the graphics slot and adjacent x4 slot.	ATI 3D RAGE II with 2 MB built-in SGRAM, supporting QuickDraw 2D/3D and QuickTime/MPEG-1 acceleration; Apple's exact support table gives 24-bit colour through 832 × 624, 16-bit through 1152 × 870 and 8-bit at 1280 × 1024. The brochure's 24-bit headline ends at 800 × 600.
Memory type
Memory type	Stock 512 MB PC2-4200 DDR2 at 533 MHz, installed in matched pairs. Up to 16 GB supported; ECC configurations available from 1 GB. Rows retain the stock drive and graphics at base and maximum supported memory.	64 MB supplied in two 168-pin DIMM sockets, no soldered system RAM; up to 128 MB using 5 V buffered EDO DIMMs. The original brochure and service source specify 60 ns or faster EDO memory, while the exact support database lists 70 ns.
Storage type
Storage type	Stock 160 GB on dual-core 2 GHz and 250 GB on dual-core 2.3 GHz and Quad. 7200 rpm Serial ATA drives; two internal bays. Optional one or two 500 GB drives. One optical bay with 16x SuperDrive supporting dual-layer DVD+R recording.	Original US Home Edition M6079LL/A and Canadian launch configuration have a 4 GB IDE drive, 12× tray-loading CD-ROM, 1.44 MB floppy and 100 MB Iomega Zip drive. Later Americas configurations documented by Apple have 6 GB, 24× CD-ROM, Zip and a 56.6 Kbit/s Apple/GV modem with Mac OS 8.0; Latin America uses a 33.6 Kbit/s modem. European 6 GB/24× configurations include video input, TV/FM tuner and Avid Cinema. These are regional configurations of the same 300 MHz model.
Expansion slots
Expansion slots	PCI Express: occupied x16 graphics slot, two open x4 slots and one open x8 slot. Older PCI and PCI-X expansion cards cannot be reused in these slots.	Two PCI 2.0 slots for approximately 7-inch cards with Mac drivers, plus Communications Slot II, video-input slot and TV/FM tuner position. The original Home Edition's modem occupies the communications slot; its Zip drive occupies the pre-cabled 5.25-inch internal SCSI bay. Apple specifies five external SCSI devices with Zip fitted.

Front ports
Front ports	USB 2.0, FireWire 400 and headphone minijack.	3.5 mm headphone output and volume buttons; infrared receiver for an optional remote supplied with the TV/FM tuner.
Back ports
Back ports	Three USB 2.0, FireWire 800, FireWire 400, two Gigabit Ethernet ports, optical Toslink input/output and analogue audio line-in/out. Four chassis USB 2.0 ports in total, plus two keyboard USB 1.1 ports. AirPort Extreme and Bluetooth 2.0 + EDR are optional, with integrated antennas; built-in support does not mean modules are included.	DB-15 monitor output, ADB, DB-25 external SCSI, two GeoPort-compatible serial connectors, PlainTalk-compatible sound input and line-level speaker output. Installing the internal modem leaves one serial port available. The original US Home Edition has a 33.6 Kbit/s data/voice modem with 14.4 Kbit/s fax; the communications slot can instead take Ethernet. Apple's exact support database lists 10BASE-T, while the maker brochure and Canadian Home configuration supply a modem, so Ethernet is not treated as standard for that configuration.
External displays
External displays	Stock GeForce 6600 LE/6600 and optional 7800 GT have one single-link and one dual-link DVI port, supporting one 30-inch Apple Cinema HD Display alongside a second display.

Size and weight detail
Size and weight detail	–	Maker brochure gives 40.6 × 19.8 × 42.8 cm (height × width × depth) and 20.2 kg, varying with installed devices. The shared service manual gives 20.18 kg without the CD-ROM; standard complete-unit weight remains unresolved and the headline mass is omitted. Gallery monitor is optional.
Power supply
Power supply	–	Exact support database and original brochure give 220 W maximum continuous, 100–125 or 200–240 V AC at 47–63 Hz. The shared Service Source instead gives 140 W for the 6500 and 90–130 or 180–264 V; the conflicting ratings are retained, and neither is treated as measured operating consumption.

In the box
In the box	Mac OS X Tiger and iLife ’05. Apple confirmed the dual-core 2 and 2.3 GHz models available on 19 October 2005, with Quad expected in early November. Macs Only reports its Quad shipped on 10 November and arrived on 11 November; these later Quad dates do not change the generation’s first sale. The exact specification sheet does not publish weight or dimensions.	Exact support page lists original software 7.6.1; later regional configurations use Mac OS 8.0. Apple lists 4 April 1997 as introduction, while its Canadian announcement promises limited supply later that spring. The maker's 1997 ordering brochure and contemporary shipping-system list establish retail sale in 1997, but the actual first-sale month remains unresolved.
