The HP C8000 is the last PA-RISC HP workstation, powered by one or two dual-core PA-8800 Mako processors, later offered with PA-8900 CPUs and features an impressive array of system and I/O options. The center of the system is the HP zx1 chipset, which also supports Itanium processors. The system is built in a sleek, silent tower casing and also available as a rack-mount option.

Chipset

HP zx1 chipset
- Pluto zx1 MIO (memory and I/O controller) connects to the processor bus (6.4 GB/s), two memory buses (each 4.25 GB/s) and seven I/O channels (aggregate 3.5 GB/s) and contains both memory and cache controllers
- Six Mercury zx1 IOAs (I/O adapters) connect the PCI-X slots and I/O devices to the zx1 MIO with an aggregate bandwidth of 3.5 GB/s on seven 0.5 GB/s channels
  1. AGP 4x graphics bus on two channels — 1.0 GB/s
  2. PCI-X 64/133 I/O slot on one channel — 0.5 GB/s
  3. PCI-X 64/133 I/O slot on one channel — 0.5 GB/s
  4. PCI-X 64/133 I/O slot on one channel — 0.5 GB/s
  5. Gigabit Ethernet and Ultra320 SCSI on PCI 64/66 on one channel — 0.5 GB/s
  6. IDE, USB, management LAN on PCI 32/33 on one channel — 0.5 GB/s
Gigabit Ethernet controller
Two-channel Ultra-320 SCSI controller
UltraATA-133 IDE controller
8 MB Flash EEPROM
