Memory
Memory	512 MB, 4 GB or 8 GB (better)	16 MB
Storage
Storage	160 GB to 250 GB (better)	1.2 GB
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.	One 132 MHz PowerPC 604 on a removable processor card, with integrated floating-point unit, 32 KB level-one cache, 256 KB level-two cache and a 44 MHz processor bus. The 50 MHz figure on the shared Japanese sheet is the family maximum, not the 132 MHz model's bus
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.	Built-in 64-bit video subsystem with 2 MB VRAM, expandable to 4 MB. Standard memory supports 24-bit colour through 832 × 624, 16-bit at 1024 × 768 and 1152 × 870, and 8-bit at 1280 × 1024. With 4 MB, 24-bit colour extends through 1152 × 870 and 16-bit to 1280 × 1024; monitor and video output simultaneously require 4 MB. Exact model tables take precedence over contradictory high-colour catalogue appendix claims
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 for the 8500/132, eight 168-pin 64-bit 70 ns-or-faster DRAM DIMM sockets, up to 512 MB supported; corresponding matching DIMMs permit interleaving. The shared Japanese page's 32 MB package is explicitly the 8500/150 and is not transferred. English support says 128 MB DIMMs were untested. 4 MB ROM
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 Japanese 8500/132 configuration has a 1.2 GB internal Fast SCSI hard disk, manual-inject Apple SuperDrive floppy and AppleCD 600i 4× CD-ROM. Shared Service Source lists 1.2 or 2 GB across 132/150/180 but does not pair an additional 132 configuration, so none is inferred. Additional internal storage bay; external SCSI up to seven devices at 5 MB/s, internal channel up to 10 MB/s
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 2.0 slots, all free with onboard video, and an internal Digital Audio/Video connector for compatible compression hardware; no NuBus slots

AirPort Extreme, Bluetooth 2.0 + EDR and a V.92 modem are optional.	One ADB connector, two GeoPort/LocalTalk-compatible serial connectors, DB-15 display output, external DB-25 SCSI, AAUI-15 and 10BASE-T Ethernet connectors, 16-bit stereo sound input/output, left/right RCA audio input/output, composite video input/output and S-video input/output. Both Ethernet connectors share one interface and cannot be used concurrently 24-bit analogue composite and S-video input/output. Japanese sheet specifies live display through 640 × 480 NTSC or 768 × 576 PAL/SECAM, capture through 320 × 240 at 25 frames/s NTSC, and a separate maximum 640 × 480 NTSC capture size without that frame-rate claim. NTSC and PAL/SECAM output supported; full-size preview is not full-size continuous capture
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.	One external display up to 1280 × 1024; available colour depth depends on VRAM. Simultaneous monitor and video output requires 4 MB VRAM
Speakers
Speakers	Built-in speaker; analogue and optical audio connections.	Built-in speaker; stereo sound and RCA line audio interfaces support 16-bit, 44.1 kHz sampling
Microphones

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 Japanese sheet gives 355.6 × 196 × 400 mm, consistent with service manual's rounded 356 × 196 × 400 mm. Catalogue gives 363 × 196 × 401 mm. Weight is unresolved and omitted from the headline; exact Japanese page says 12.7 kg, but English support, service manual and catalogue give 25 lb or approximately 11.3 kg. All qualify weight by installed devices
Power supply
Power supply	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.	100–240 V AC automatically configured, single phase, 50–60 Hz. Service Source distinguishes 225 W maximum DC output from AC consumption
Power use
Power use	–	340 W maximum continuous AC input and 520 W peak input, excluding monitor; exact Japanese specification and shared Service Source agree

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.	Original system software 7.5.3. English support gives 22 April 1996 as introduction; Apple's May 1996 catalogue lists the exact 8500/132 as an offering, supporting release year 1996. Actual first-sale month/day remains unconfirmed
