CPUSingle 1 GHz, dual 1.25 GHz or dual 1.42 GHz PowerPC G4; each physical processor has 256 KB on-chip L2 cache. L3 cache is 1 MB on the single 1 GHz, 1 MB per processor on dual 1.25 GHz and 2 MB per processor on dual 1.42 GHz. Bus is 133 MHz on the single model, 167 MHz on dual models.275 MHz PowerPC 603e with integrated floating-point unit, 32 KB internal cache and 64-bit PowerPC bus. UK and Dutch exact graphite specifications give 512 KB L2 cache. Shared service describes another 275 MHz configuration with the same features as the basic 5500/225 apart from clock speed; optional 256 KB family cache does not replace the documented graphite 512 KB value.
GPUSingle 1 GHz: NVIDIA GeForce4 MX with 64 MB DDR. Dual 1.25/1.42 GHz: ATI Radeon 9000 Pro with 64 MB DDR. Optional NVIDIA GeForce4 Titanium and ATI Radeon 9700 Pro, each 128 MB DDR; independent CTO options stay in details.2 MB SGRAM and built-in hardware acceleration for 2D QuickDraw and 3D QuickDraw 3D/RAVE. Exact archived Dutch family specifications identify ATI 3D Rage II and support 24-bit colour through 800 × 600 on the built-in CRT. Headline resolution is this explicitly documented built-in colour mode, not a fixed pixel matrix or established maximum for every colour depth. Shared service lists 640 × 480, 800 × 600 and 832 × 624 at 32 bits per pixel, 1024 × 768 and 1152 × 870 at 16 bits, and 1280 × 1024 at 8 bits; it does not establish all of these as exact regional built-in display limits.
Memory typeSingle 1 GHz: 256 MB PC2100 DDR at 266 MHz; dual 1.25 GHz: 256 MB PC2700 DDR at 333 MHz; dual 1.42 GHz: 512 MB PC2700. Four DIMM slots support up to 2 GB. Configurations retain stock drives and GPUs at base and maximum supported memory.Graphite UK and Dutch family configurations have 32 MB EDO RAM, expandable to 128 MB in two 168-pin DIMM sockets. No system RAM is soldered on the logic board. Archived exact Dutch page specifies noncomposite 5 V, 60 ns or faster EDO DIMMs with 1K or 2K refresh. Shared service also permits 5 V fast-page DIMMs and warns that mixing types can use fast-page timings. Basic service configuration has 16 MB. 4 MB ROM.
Storage typeStock 60/80/120 GB 7200 rpm Ultra ATA/100 drives on 1/1.25/1.42 GHz respectively. Lower models have Combo DVD-ROM/CD-RW; top model has SuperDrive (DVD-R 4x, CD-R 16x). Four bays support two ATA/100 and two ATA/66 drives; two optical bays, one occupied. Optional 180 GB drive, SuperDrive on lower models and second Combo drive are not assumed in every configuration.Exact graphite family configuration has a 4 GB IDE hard drive, internal 24× CD-ROM and Apple SuperDrive floppy. Shared service also documents a basic 275 MHz configuration inheriting 16 MB RAM, a 2 GB or larger drive and 12× CD-ROM from the basic 225 MHz model; the 2 GB configuration is the documented minimum, not a claimed universal shipped capacity. Optical drives and software differ between these configurations. Shared service describes the floppy as 1.4 MB; the archived Dutch page uses the same maker wording.
Expansion slotsFour open full-length 64-bit 33 MHz PCI slots and AGP 4x graphics slot.One 32-bit PCI 2.0 slot for a 7-inch card with Macintosh drivers; communications slot occupied by the supplied graphite modem or optional Ethernet; video-input slot and TV/FM tuner bay. Graphite family specification includes TV/FM tuner and video-input card. Avid Cinema video-editing hardware is optional and requires Apple Video System. NuBus cards are not compatible with the PCI slot.

Graphite family modem supports data up to 33.6 Kbit/s, fax up to 14.4 Kbit/s, voice, answering-machine and hands-free functions; data rate depends on connection and provider. Archived page lists MNP4, V.42, MNP5 and V.42bis. Ethernet is a communications-slot option, not universally fitted. No USB or FireWire.
External displaysTwo displays in extended desktop or mirroring modes. ADC and DVI connectors with included DVI-to-VGA adapter; digital up to 1920 × 1200, analogue up to 1600 × 1200. A second ADC display needs a separately sold adapter.Computer-monitor video mirroring requires the optional external-video connector kit. Shared service supports mirroring at 640 × 480, 800 × 600 or 832 × 624; this does not establish an independent extended desktop. Avid Cinema provides optional PAL/NTSC video editing and output and requires the video-input system. Included TV/FM reception is not proof of included TV output.
SpeakersBuilt-in speaker; optional Apple Pro Speakers.Two built-in stereo speakers and 16-bit stereo sound input/output, with SRS surround-sound enhancement. Shared service supports recording at 11, 22 or 44 kHz. Front headphone and rear speaker outputs are separate.
Microphones–Built-in microphone plus external sound-input port supporting PlainTalk microphones. Shared service explicitly excludes the earlier Omni microphone and attenuated RCA adapter.
Keyboard and mouseApple Pro Keyboard, Apple Pro Mouse, USB keyboard extension, DVI-to-VGA adapter and modem cable.Exact archived Dutch ordering page identifies graphite Family Macintosh M6183 with keyboard, mouse, cables and model-specific software. Original UK Christmas 1997 brochure shows the graphite computer with matching keyboard and mouse, with TV/FM tuner and video-in listed in its 275 MHz specification. The screen artwork is original maker photography; it is not a clean unlit-screen alternative.

Size and weight detailMaker reference 19.1 kg varies with configuration and manufacturing. Height 43.2 cm, width 22.7 cm, depth 46.8 cm.Exact archived Dutch family page gives 40.6 × 19.8 × 42.8 cm and 20.2 kg, values resembling the companion tower rather than the pictured all-in-one. Shared service gives 445 mm height but swaps the family width/depth compared with other original all-in-one brochures, and prints internally inconsistent 17/19 lb versus 21.15 kg weights. These unresolved exact-model measurement conflicts are not promoted into headline weight or dimensions, and sibling-model measurements are not substituted.
Power supply100–125 V or 200–240 V AC, 50–60 Hz; maximum current 6.5 A at low voltage or 7.5 A at high voltage. No wattage is supplied by this sheet.Archived exact Dutch family specifications give 220 W maximum continuous input, with regional 200–240 or 100–125 V AC at 47–63 Hz and energy-saving sleep. Shared service gives 100–240 V AC at 47–63 Hz, a separate 125 W entry and 220 W maximum for all line/load conditions. These qualified ratings are not measured operating consumption.
Noise–Shared service describes a variable-speed enclosure fan and separate processor cooling fan, without a measured acoustic figure.
In the boxMac OS X with Classic environment rather than native Mac OS 9 boot; iLife and productivity software. Single 1 GHz and dual 1.25 GHz were available on 28 January 2003; dual 1.42 GHz was announced for the following month and subsequently reviewed. Its later availability does not change the generation’s first on-sale date.Shared service graphite configuration includes Mac OS 8.0. Original UK Christmas brochure describes purchase between 1 November and 31 December 1997 for a software offer; exact Dutch product ordering page is dated September 1997 and lists 275 MHz M6183. These establish sale in 1997; actual first-sale month or day remains unresolved. UK software includes Apple Magic Collection, Actua Soccer, Kai's Power Goo and multimedia reference titles; promotional software is not another hardware generation. Product resource is the original Dutch Apple family page covering exact 225/275 configurations; the support resource is the current official Earlier Power Mac family document index in English (Macau region), which has no exact 275 MHz entry. No exact surviving English maker support specification record or user guide was recovered.
