HP Z is a series of professional workstation computers developed by Hewlett-Packard. The first-generation desktop products were announced in March 2009, replacing the HP xw series desktop workstations.[1] The product line expanded to mobile with the announcement of ZBook in September 2013, replacing HP's EliteBook W-series mobile workstations.[2] The Z workstations mainly compete against Dell's Precision workstations, Lenovo's ThinkStation and ThinkPad P series workstations, as well as Apple's Mac Pro and MacBook Pro.

First generation
The HP Z800, HP Z600 and HP Z400 were announced in March 2009, offering Intel Nehalem-based Xeon processors and a new chassis design.[1] An entry-level model, HP Z200, was announced in January 2010 at CES 2010.[3] A small-form-factor version of the Z200, along with Intel Westmere Xeon processor refresh, were introduced to the lineup in March 2010.[4] Z210, the successor of Z200, was announced in April 2011 with Intel Sandy Bridge Xeon E3 processors.[5] An all-in-one workstation Z1 featuring Sandy Bridge E3 processors was introduced in February 2012.[6]
Second generation

The second-generation workstations Z820, Z620 and Z420 were announced in March 2012, featuring Intel Sandy Bridge-EP Xeon E5 processors.[7] The entry-level Z220 was refreshed with Intel Ivy Bridge Xeon E3 v2 processors in June 2012.[8] Z230, successor to Z220, was introduced in July 2013 with Intel Haswell-WS Xeon E3 v3 processors. Z820, Z620 and Z420 were updated to Intel Ivy Bridge Xeon E5 v2 processors in September 2013.[3] The second-generation Z1 G2 all-in-one was announced at CES 2014.[9]
Third generation
The third-generation workstations Z840, Z640 and Z440 were announced in September 2014, featuring Intel Haswell Xeon E5 v3 processors.[10] The processors were later updated to Broadwell in April 2016.[11] The entry-level Z240 was announced in September 2015 with Intel Skylake E3-1200 v5 processors, and later updated to Kaby Lake Xeon E3-1200 v6 processors.[12] The third-generation all-in-one Z1 G3 was announced in April 2016 with Intel Skylake processors.[13] A mini workstation, Z2 Mini G3, was announced in November 2016.[14][15]
Fourth generation
The fourth-generation workstations Z8 G4, Z6 G4 and Z4 G4 were announced in September 2017, shipping with Intel Skylake first-generation Xeon Scalable or W-series processors.[16]Cascade Lake second-generation processors were made available in April 2019.[17] Entry-level Z2 G4 and Z2 Mini G4 were announced in July 2018, featuring Intel Coffee Lake Xeon E-2100 processors.[18]
Fifth generation

HP made a major update to its Z Workstation portfolio by launching G5 editions of its HP Z4, Z6, Z8, and Z8 Fury workstation in April 2023. The HP Z4 G5 edition features a new workstation-specific Sapphire Rapids CPU family, the single-socket Intel Xeon W-2400 Series, available with 6 to 24 cores. The machine supports up to 512 GB of DDR5 RAM and can host up to two dual-slot graphics cards, up to the Ada Lovelace-based Nvidia RTX 6000 (48 GB), which will benefit multi-GPU aware viz and rendering applications. The HP Z6 G5 supports the single-socket Intel Xeon W-3400 Series workstation CPU from 12 to 36 cores (not including the flagship 56-core Xeon w9-3495X). It offers double the memory of the HP Z4 G5 (up to 1 TB), more memory bandwidth, and up to three double-width GPUs. The HP Z8 G5 features Sapphire Rapids fourth-generation Xeon Scalable processors rather than the single-socket workstation-specific Xeons available in the other G5 machines. This gives it a dual CPU capability, although it only supports models up to 32 cores, meaning 64 cores (2 x 32) is the maximum configuration. The Dual CPU configuration means there's a limit of two double-width GPUs and 1 TB of memory. On top of the line, the HP Z8 Fury G5 is HP's top-end Sapphire Rapids workstation. It supports the whole range of Intel Xeon W-3400 series workstation CPUs, including the flagship 56-core Intel Xeon w9-3495X. It supports twice as much memory as the Z6 and Z8 and up to four double-width GPUs, which is of interest to those pushing the boundaries of GPU rendering, AI, or simulation, and has several server-grade features.
