Each zone is software-controlled by the system to only cool when necessary, making for a more efficient (and quieter) cooling solution.ĪTA/100 bus for optical drives- This technology allows optical storage to read/write data faster.ĭouble-layer SuperDrives - Power Mac G5 (Early 2005) 16x SuperDrives support double-layer (DVD+R DL) discs. These ports are in addition to the existing analog sound input and output ports.Ĭooling zones - Nine case fans and blowers are logically grouped into four separate cooling zones in the Power Mac G5. USB 2.0 - All USB ports on the Power Mac G5 support the USB 2.0 standard, which accommodates more high speed peripherals.ĭigital audio in and out - The Power Mac G5 introduces two new optical audio (S/PDIF) ports, allowing for optical audio input and output. Both NVIDIA and ATI graphics cards are offered for the Power Mac G5. For more information, see the “ AGP/PCI Card” topic in the Take Apart chapter.Ĩx AGP bus - This bus provides a higher amount of data transfer to and from the graphics card. Both 100 and 133 MHz PCI-X slots are included in higher-end Power Mac G5 computers. PCI-X slots - Higher-bandwidth PCI slots allow for greater amounts of data when using expansion cards that demand high performance. The 7200 rpm drives come in 80, 160, 250, or 400 GB capacity. Serial ATA hard drives - Unlike older parallel drives, the new serial ATA drives in the Power Mac G5 offer up to 150 MB/s data throughput. PowerPC G5 - The Power Mac G5 computer incudes the new 64-bit PowerPC G5 processor running at 1.6, 1.8, 2.0, 2.3, 2.5, or 2.7 GHz, well beyond the speeds of G4 processors.
