HP zx6000 are dual-processor Itanium workstations from HP, released in 2002. The zx6000 were based technically on the zx2000 workstation with an HP zx1 Itanium system design, also used in a few PA-RISC servers and workstations. HP zx6000 have higher I/O and memory bandwidth and three times as much memory as HP zx2000 workstations and are SMP-capable for up to two processors.

The zx6000 were designed for rack-mounting (2U) but with the optional tower kit could be converted to a sleek, loud standalone unit. Rack-mounted rx2600 servers are closely related.
HP zx6000 Itanium workstations with fast processor options were probably the fastest HP-UX workstations ever released by HP, even faster than the two years younger final HP c8000 PA-RISC workstation. Itanium workstations were discontinued in September 2004 by HP after releasing zx2000 and zx6000 and technical Unix workstations were discontinued altogether two years later.
HP zx6000 workstations were sold with HP-UX and Linux (more affordable) in a variety of configurations and graphics options, mainly for 3D and visualization.

Chipset
HP zx2000 Itanium workstations are based on an HP zx1 chipset with two main components — MIO memory and I/O controller (HP Pluto) and IOA I/O adapters (HP Mercury), as used in PA-RISC c8000 and Itanium workstations like zx2000 as well.
- HP zx1 chipset, on original HP Itanium design based on two main components: central memory and I/O controller (MIO), and I/O adapters (IOAs).
- HP Pluto, zx1 MIO, the chipset controller connects the processor bus, two memory buses and seven I/O channels. Contains memory and cache controllers.
- Six HP Mercury, zx1 IOAs, connect PCI-X slots and I/O devices to the zx1 MIO on seven I/O channels (3.5 GB/s)

Compared to the competition at the time, Itanium computers were exceptionally strong in floating-point use cases, beating other CPUs in FP with more than twice the clock. Integer and general workloads were much weaker in Itanium, only barely beating PA-RISC, but a Madison 1.5 GHz much higher rater Intel and AMD processors.
