●
Microprocessors: The Power Mac G5 computer is available in dual 2.0 GHz, 2.3 GHz, and 2.7 GHz
configurations. For more information, see PowerPC G5 Microprocessor (page 20).
●
Processor system bus: The processor interface system bus runs at half the speed of the system
microprocessor. For more information, see Processor Bus (page 21).
●
Memory caches: The PowerPC G5 microprocessors used in the Power Mac G5 computer have an internal
512 KB level 2 cache.
●
Memory bus: The main memory bus is 128 bit 400 MHz. For more information, see Main Memory Bus (page
21).
●
DDR SDRAM: Depending on configuration, the Power Mac G5 has four or eight DIMM slots for 184 pin
DIMMs (dual inline memory modules) using unbuffered DDR (double data rate) SDRAM 64-bit, 400 MHz
(PC3200) devices for a maximum of 4 GB or 8 GB. For more information, see Main Memory Bus (page 21).
●
Liquid cooling system: One configuration has a liquid cooling system. For more information, see Liquid
Cooling System (page 29).
●
AGP 8x Pro slot: The computer has an AGP 8x Pro slot with an accelerated graphics card installed. For
more information, see Accelerated Graphics Port Bus (page 21).
●
PCI expansion slots: Some configurations support three 64-bit 33 MHz PCI slots. For more information,
see PCI or PCI-X Expansion Slots (page 22).
●
PCI-X expansion slots: Some configurations support three PCI-X expansion slots: one slot supports a
maximum of 133 MHz and two slots support a maximum of 100 MHz. For more information, see PCI or
PCI-X Expansion Slots (page 22).
●
Hyper Transport bus: The Power Mac G5 supports the high-speed bus architecture between the memory
controller and device I/O. For more information, see HyperTransport Technology (page 23).
●
Graphics card: The Power Mac G5 computer comes standard with one of the following graphics cards:
the ATI Radeon 9600 with 128 MB RAM or the ATI Radeon 9650 with 256 MB RAM. The NVIDIA GeForce
6800 Ultra DDL with 256 MB RAM is a build-to-order option.For more information, see Graphics Cards (page
28).
●
Hard disks: An internal 7200 rpm Serial ATA (SATA) hard disk occupies one of two drive bays and functions
as the default boot disk. A second SATA drive is available as a build-to-order option. Hard disk capacities
are 160 GB, 250 GB, and a 400 GB build-to-order option. For more information, see Serial ATA Interface (page
26).
●
Power supply: The Power Mac G5 computer comes with a 450 W or 600 W power supply.
