Memory
Memory	512 MB, 4 GB or 8 GB (better)	16 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 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	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 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 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.	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 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.	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	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.	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.

Refresh rate	–	66.67 Hz
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	Two USB 2.0, FireWire 800, FireWire 400, Gigabit Ethernet, optical S/PDIF input/output and analogue audio line-in/out. Three chassis USB ports in total, plus keyboard USB 1.1 ports. AirPort Extreme, Bluetooth 2.0 + EDR and a V.92 modem are optional.	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	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.	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; analogue and optical 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, Apple Mouse, USB extension cable 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	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.	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	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.	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’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 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.
