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.	100 MHz PowerPC 603e with integrated floating-point unit. Exact Apple support lists 32 KB L1 cache and a 64-bit processor data path at 40 MHz; Original exact Apple TIL 19602 and May 1996 Apple Facts instead say 16 KB L1, an unresolved maker conflict. Apple's separate comparison table gives the narrower memory bus as 32-bit at 37.5 MHz, not the same path. Optional 256 KB L2 High Performance Module M4849LL/A is a 160-pin SIMM, not interchangeable with the later 5400/6400 DIMM. Original ordering description and cache note establish it as optional despite the support/service tables listing 256 KB without that qualification.
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.	1 MB built-in DRAM framebuffer; exact support and shared service video-mode list support 640 × 480 with 16-bit colour. Other higher-resolution timing pages in the shared service do not establish those as supported modes for the built-in 14-inch display.
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.	16 MB standard in one 72-pin SIMM, with a second socket for expansion to 64 MB. No memory soldered on board; SIMMs can be installed individually. Exact original TIL 19602 specifies 70 ns, while exact current support and shared service specify 80 ns or faster. The timing difference remains qualified. Shared comparison lists an 8 MB minimum, without an exact factory bundle.
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.	800 MB IDE hard drive, 1.44 MB Apple SuperDrive floppy and quadruple-speed AppleCD 600i in original M4982LL/A ordering information. May 1996 Apple Facts says CD-ROM is present in most configurations; no undocumented drive-free factory combination is added. Shared service lists larger family drives without coupling them to an exact 5260/100 bundle.
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.	LC-compatible PDS, 68040-bus communications slot for optional modem or Ethernet, optional video-input card and TV tuner bay. PDS is not a direct connection to the PowerPC processor; processor-dependent cache/FPU cards are not compatible. Optional MPEG Media System requires the video-input card. Video capture accepts NTSC, PAL and SECAM; tuner standard varies by region.

Display type
Display type	–	Built-in 14-inch nominal shadow-mask colour CRT with 12.3-inch viewable diagonal in the exact original ordering description and technical sheet. Shared Service Source instead says 12.8-inch viewable; exact model wording is retained. Dot pitch 0.28 mm; tilt-and-swivel base. A CRT has selectable raster modes rather than a fixed LCD pixel grid.
Display features
Display features	–	640 × 480 at 16-bit colour and 66.67 Hz in the exact original TIL 19602 technical sheet. Shared service agrees on 66.7 Hz; a separate service timing table headed 60 Hz instead gives 15 ms, so no second 60 Hz mode is inferred.

Front ports
Front ports	USB 2.0, FireWire 400 and headphone minijack.	Headphone output, push-button volume and display brightness controls, infrared remote receiver.
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.	ADB, external DB-25 SCSI, two RS-232/422 modem/printer serial ports with LocalTalk, PlainTalk-compatible sound input and stereo sound output. Ethernet requires an optional communications-slot card; no GeoPort inferred from a similar-looking serial connector. Exact original TIL gives six external SCSI devices in its ports section but five in expansion; maker catalogue says five and shared service seven. Limits remain source-qualified.
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. Optional Quadro FX 4500 has two dual-link DVI outputs for two 30-inch displays and a stereo 3D connector. DVI-to-VGA adapter included.	Optional Apple External Video Connector provides DB-15 mirroring, with a compatible display. Optional Apple Presentation System converts the mirrored output for television/projector or VCR use; it is not an independent extended desktop.
Speakers
Speakers	Built-in speaker and optical/analogue external audio connections.	Two built-in speakers and 16-bit stereo output. Shared service specifies 22 kHz playback and 11/22 kHz recording, with ordinary audio-CD playback. Stereo input connectors are combined to mono for recording/play-through; do not treat the connector as stereo capture.
Microphones
Microphones	–	Built-in microphone for mono recording; rear microphone/line input supports PlainTalk-compatible microphones.
Keyboard and mouse
Keyboard and mouse	Apple Keyboard, Mighty Mouse, USB keyboard extension and DVI-to-VGA adapter.	Original M4982LL/A ordering description includes matching keyboard, mouse and necessary cables. External speakers, optional cache, Ethernet, video input/output, TV tuner and MPEG expansion are separate. Maker photograph shows the exact 5260/100 with keyboard and mouse.

Size and weight detail
Size and weight detail	–	Exact original TIL 19602 technical sheet gives 44.5 × 38.3 × 40.6 cm (height × width × depth), 20.5 kg/45 lb; exact current support agrees on 16-inch depth and 45 lb. May 1996 Apple Facts instead gives 41.4 cm depth, 20.2 kg/44.9 lb, varying with installed devices. Shared service swaps width/depth and has inconsistent weight units. Exact original technical-sheet dimensions and complete-unit kg figure are used; disagreement remains explicit.
Power supply
Power supply	–	Exact current support lists 125 W maximum , 110–240 V AC at 50–60 Hz. Exact original TIL 19602 instead gives 240 W maximum at 110–240 V AC 50–60 Hz; shared service gives 100–240 V 47–63 Hz, 240 W maximum and a separate 220 W all-line/load maximum. Conflicting ratings remain qualified; no universal headline operating consumption is assigned.

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.	System 7.5.3 and 4 MB ROM in exact Apple support; original ordering description calls it System 7.5. Apple records introduction on 15 April 1996; current May 1996 maker education catalogue establishes sale in 1996, not a first-sale month. Release remains year precision. North American education 5260/100 is separate from later 5260/120 and international Performa bundles.
