Processor	2 × PowerPC G5 2000 MHz (Power Mac Early 2005), 2 × PowerPC G5 2300 MHz (Power Mac Early 2005) or 2 × PowerPC G5 2700 MHz (Power Mac Early 2005)	PowerPC 601 100 MHz (Power Macintosh 7200/100)

Graphics
Graphics	ATI Radeon 9600 (128 MB) or ATI Radeon 9650 (256 MB)	–
Memory
Memory	512 MB, 4 GB or 8 GB (better)	8 MB
Storage
Storage	160 GB to 250 GB (better)	800 MB
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.	100 MHz PowerPC 601 with integrated floating-point unit, 32 KB L1 cache and 50 MHz processor bus. Exact improved-model developer table lists no fitted L2 cache for the 7200/100; the shared maker catalogue documents an optional 256 KB L2 cache. The developer note introductory narrative contains a 7600/100/604 typo; its explicitly labelled processor/configuration tables establish the 7200/100 as a 601 model.
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.	1 MB VRAM standard, expandable to 4 MB. Original Apple catalogue describes a 32-bit graphics data path with 1 MB and 64-bit with 2 MB. It supports 24-bit colour on 16-inch displays with 2 MB and on 21-inch displays with 4 MB; exact modes depend on installed VRAM and a compatible external monitor.
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.	Exact April 1996 improved-model developer table lists 8 MB RAM in four 168-pin DIMM slots; the shared May 1996 7200/100 and 7200/120 catalogue describes 8 MB or 16 MB family configurations and expansion to 256 MB. No exact 100 MHz model 16 MB factory configuration is inferred from the combined table.
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.	Exact developer and original Apple support configuration tables list an 800 MB hard disk for the 7200/100. The joint May 1996 7200/100 and 7200/120 catalogue instead lists 1.2 GB with regional configuration wording; that unresolved family-level difference is not assigned as another exact 100 MHz configuration. A built-in CD-ROM is confirmed for all improved models; the joint catalogue gives quadruple-speed CD-ROM and Apple SuperDrive floppy. One additional 3.5-inch storage-device bay.
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 expansion slots; the maker catalogue lists support for six SCSI devices. Apple explicitly supports its optional PCI Token Ring Card on 7200/100 and 7200/120, unlike earlier 7200/75 and 7200/90. The contemporary support article says the Token Ring card is incompatible with the PCI DOS Compatibility Card.

AirPort Extreme, Bluetooth 2.0 + EDR and a V.92 modem are optional.	Two GeoPort-compatible serial ports, ADB, monitor output, external SCSI and 16-bit stereo audio input/output. Built-in LocalTalk, 10BASE-T and AAUI Ethernet. The original enhanced-model support article describes CurioPrime multihoming for simultaneous AppleTalk network ports.
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.	External monitor required. Built-in video supports up to 1280 × 1024 with 4 MB VRAM in the original maker catalogue. The primary shared100/120 maker photograph shows a separate display and keyboard/mouse; the display is not built into the computer.
Speakers
Speakers	Built-in speaker; analogue and optical audio connections.	–
Keyboard and mouse
Keyboard and mouse	Apple Keyboard, Apple Mouse, USB extension cable and DVI-to-VGA adapter.	The shared maker photograph shows keyboard, mouse and an external monitor; this is an illustrated setup, not evidence all accessories were included in each bundle. The shared 7200 user guide says monitor/keyboard vary with what was purchased and the PlainTalk microphone is optional.

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.	Original May 1996 joint 7200/100 and 7200/120 Apple Facts table gives 15.7 × 36.6 × 42.9 cm (height ×width ×depth), 9.9 kg/22 lb, varying with installed devices. These are computer measurements, excluding the separately shown monitor and peripherals.
Power supply
Power supply	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.	–

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.	System 7.5.3 in the exact improved-model developer note. Original Apple May 1996 current product catalogue establishes sale in 1996; actual first-sale month is unresolved, so release stays year precision. Developer-note publication 23 April 1996 and support-article publication 25 April 1996 are not treated as retail-launch dates. No successor relationship is inferred merely from shared family naming.
