HP Z is a series of professionalworkstation computers developed byHewlett-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 ofZBook in September 2013, replacing HP'sEliteBook W-series mobile workstations.^[2] The Z workstations mainly compete againstDell'sPrecision workstations,Lenovo'sThinkStation andThinkPad P series workstations, as well asApple'sMac Pro andMacBook Pro.

The HP Z800, HP Z600 and HP Z400 were announced in March 2009, offering IntelNehalem-basedXeon processors and a new chassis design.^[1] An entry-level model, HP Z200, was announced in January 2010 atCES 2010.^[3] A small-form-factor version of the Z200, along with IntelWestmere Xeon processor refresh, were introduced to the lineup in March 2010.^[4] Z210, the successor of Z200, was announced in April 2011 with IntelSandy Bridge Xeon E3 processors.^[5] Anall-in-one workstation Z1 featuringSandy Bridge E3 processors was introduced in February 2012.^[6]

The second-generation workstations Z820, Z620 and Z420 were announced in March 2012, featuring IntelSandy Bridge-EP Xeon E5 processors.^[7] The entry-level Z220 was refreshed with IntelIvy Bridge Xeon E3 v2 processors in June 2012.^[8] Z230, successor to Z220, was introduced in July 2013 with IntelHaswell-WS Xeon E3 v3 processors. Z820, Z620 and Z420 were updated to IntelIvy Bridge Xeon E5 v2 processors in September 2013.^[3] The second-generation Z1 G2 all-in-one was announced atCES 2014.^[9]

The third-generation workstations Z840, Z640 and Z440 were announced in September 2014, featuring IntelHaswell Xeon E5 v3 processors.^[10] The processors were later updated toBroadwell in April 2016.^[11] The entry-level Z240 was announced in September 2015 with IntelSkylake E3-1200 v5 processors, and later updated toKaby Lake Xeon E3-1200 v6 processors.^[12] The third-generation all-in-one Z1 G3 was announced in April 2016 with IntelSkylake processors.^[13] A mini workstation, Z2 Mini G3, was announced in November 2016.^[14][15]

The fourth-generation workstations Z8 G4, Z6 G4 and Z4 G4 were announced in September 2017, shipping with IntelSkylake 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 IntelCoffee Lake Xeon E-2100 processors.^[18]

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-specificSapphire 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 theAda 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 featuresSapphire 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-endSapphire 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.
