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.	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 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.	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 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.	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	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.	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.

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	Two displays in extended desktop or mirrored modes. Radeon 9600 supports two displays up to 1920 × 1200; Radeon 9650 supports one 30-inch Apple Cinema HD Display via dual-link DVI. Optional 6800 Ultra DDL supports two 30-inch displays. DVI-to-VGA adapter included.	–

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.	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	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.	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’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 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.
