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.	160 MHz PowerPC 603e with integrated floating-point unit, 40 MHz system bus and 32 KB level-one cache; optional 256 KB level-two cache on a 160-pin DIMM card
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 video with 1 MB EDO video-memory DIMM, expandable to 2 MB EDO or up to 4 MB SGRAM. Exact support table gives 16-bit colour through 832 × 624 and 8-bit at 1024 × 768 or 1152 × 870 with standard 1 MB; 1280 × 1024 needs expanded video memory and permits 8-bit at 2 MB or 16-bit at 4 MB
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; maximum 96 MB using three 168-pin 64-bit 3.3 V unbuffered EDO DIMMs, 60 ns or faster. Each socket supports up to 32 MB; slot one only supports single-bank DIMMs. No memory soldered to board; 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.	1.2 GB internal IDE hard disk, manual-inject 1.44 MB Apple SuperDrive floppy and 8× ATAPI CD-ROM
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 expansion slots, 45 W combined allowance. Exact English support says one 7-inch and two 12-inch slots; shared Service Source instead specifies one full-size 12.28-inch slot and all three support 6.88-inch cards. Card-length conflict retained. No separate Comm Slot II on this original 160 model; later 200 model differs

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.	Shared Service Source gives 139 × 385 × 442 mm and 9.5 kg, but its corresponding 24 lb figure is inconsistent. Published metric weight retained without conversion; installed equipment changes weight
Power supply
Power supply	450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.	Manually switched mains. Exact support specifies 110/220 V, 47–63 Hz and 150 W maximum; shared Service Source specifies 90–270 V switchable 110/220 V and 200 W maximum excluding monitor. These unresolved maximum-rating differences are retained without treating them as measured operating consumption
Materials

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.	Exact Apple support lists 7 November 1996 as introduction. Apple Tech Info Library dated 18 November 1996 explicitly says the exact 4400/160 is currently available in Europe, supporting November 1996 sale precision without inventing a day. Contemporary German coverage planned availability there for December; regional delivery differed. This is the Europe-only 160 MHz version, not the later 200 MHz or renamed Far East 7220.
