Graphics
Graphics	NVIDIA GeForce4 MX (32 MB) or ATI Radeon 9000 Pro (64 MB)	ATI RAGE 128 (16 MB)
Memory
Memory	256 MB, 512 MB or 2 GB (better)	64 MB or 1 GB
Storage
Storage	60 GB to 120 GB (better)	10 GB
CPU
CPU	Dual 867 MHz, dual 1 GHz or dual 1.25 GHz PowerPC G4 processors; each physical processor has 256 KB on-chip L2 cache. 867 MHz and 1 GHz have 1 MB DDR SRAM L3 per processor; 1.25 GHz has 2 MB. System bus 133 MHz on dual 867, 167 MHz on dual 1/1.25 GHz. CPU count describes physical processors; supplier is not inferred.	Single 350 or 400 MHz PowerPC G4 with Velocity Engine; 100 MHz system bus. Exact EveryMac PCI sheets specify 1 MB backside L2 cache; the retained maker page lists 512 KB or 1 MB without exact ties. No silicon supplier is inferred from Apple/Motorola/IBM co-development.
GPU
GPU	Dual 867 MHz: NVIDIA GeForce4 MX 32 MB DDR. Dual 1/1.25 GHz: ATI Radeon 9000 Pro 64 MB DDR. Optional NVIDIA GeForce4 Ti 128 MB; independent CTO options are not expanded into unsupported stock combinations.	ATI RAGE 128 PCI graphics with 16 MB SDRAM. This is the PCI/Yikes board, distinct from the contemporary AGP model.
Memory type
Memory type	Dual 867 MHz: 256 MB PC2100 DDR SDRAM at 266 MHz. Dual 1 GHz: 256 MB PC2700 DDR at 333 MHz; dual 1.25 GHz: 512 MB PC2700. Four DIMM slots support up to 2 GB. Configurations preserve stock processor/drive/graphics ties at base and maximum memory.	64 MB PC100 SDRAM standard. Four DIMM slots support up to 1 GB. Configurations preserve 10 GB factory storage at base and maximum RAM.
Storage type
Storage type	60/80/120 GB 7200 rpm Ultra ATA/100 stock drives respectively. Dual 867 MHz has Combo DVD-ROM/CD-RW (CD-R 16x); faster models SuperDrive (DVD-R 2x, CD-R 8x). Four hard-drive bays support two ATA/100 and two ATA/66 drives, or up to four SCSI drives with a separately sold PCI card. Two optical bays, one occupied; optional second Combo drive. Maker optional storage choices remain in details rather than assumed CPU cross-pairs.	400 MHz launch configuration: 10 GB Ultra ATA/33 and 32x CD-ROM; October 1999 speed-reduced 350 MHz retains those factory specifications (EveryMac). Retained Apple sheet also lists 24x CD-ROM without precise configuration ties. Optional drives are not expanded into unsupported cross-combinations.
Expansion slots
Expansion slots	Four open full-length 64-bit 33 MHz PCI slots and dedicated AGP 4x graphics slot.	Three open 33 MHz PCI slots plus the 66 MHz PCI slot used by graphics.

Optional 11 Mbps AirPort 802.11b card. Bluetooth is a separately listed adapter, not built-in. No FireWire 800 in this 2002 generation.	Two chassis USB ports at 12 Mbps, two external FireWire 400 ports, VGA, 10/100BASE-T Ethernet, 56K modem and analog audio input/output. The retained maker FireWire count of three is not supported by the exact PCI port specification (EveryMac). No AirPort slot; keyboard ports are not included.
External displays
External displays	Two displays in extended desktop or mirroring modes; ADC and DVI with included DVI-to-VGA adapter. Connecting two ADC displays requires a separately sold DVI-to-ADC adapter.	VGA output from the PCI graphics card.

Size and weight detail
Size and weight detail	Exact maker reference weight 19.1 kg varies with configuration and manufacturing process; height 43.2, width 22.7, depth 46.8 cm. These published dimensions differ slightly from earlier G4 sheets and are retained.	Maker publishes 17-inch height, 8.9-inch width, 18.4-inch depth and 30-pound weight. Metric main fields omitted; no unit conversion or sibling measurements.
Power supply
Power supply	100–125 V AC or 200–240 V AC, 50–60 Hz. Maximum current 6.5 A at low voltage or 7.5 A at high voltage; maker publishes no maximum wattage here.	Maximum continuous power 200 W.
In the box
In the box	Mac OS X 10.2 Jaguar as default startup system, plus bootable Mac OS 9.2.2; iMovie, iPhoto, iTunes and iDVD for SuperDrive. Maker August 13 release says dual 867/1 GHz available that week, so first sale uses August month precision. Actual dual-1.25 GHz shipping confirmed 18 September. January 2003 FireWire 800 models and June 2003 reissue are separate generations.	Mac OS 8.6. Full contemporary AppleInsider report says Jobs confirmed the 400 MHz configuration shipping immediately on 31 August 1999; the Canadian maker release instead promises September. First-sale month uses the named US report without implying universal regional availability.
