The HP 9000 725 PA-RISC workstations from 1992 were the smaller replacements for the HP 9000 750 servers while still offering the same amount of I/O options. The technical design is based on their 715 workstations counterparts in a slighty smaller desktop case, in dimensions very popular in the early 1990s.

Two different architectures were offered, one based on PA-7100 processors and the original HP ASP chipset, an early-1990s. The original 725/50 was billed by HP as low-cost workstation for applications that require fast X Window System performance and 2D/3D wireframe graphics such as CAD, MCAD, CASE and publishing. All at price points comparable to PCs.

The newer 725 design was based on the LASI chipset and newer LC processors, technically close to the pizzabox HP 9000 712 workstations. The 725/100 was a high-performance, cost- effective expandable desktop system with new CPU and system-integrated graphics.

Compared to the closely related 712 and 715 workstations, the 725 workstations was not as popular, even though offering good I/O options and a similar case and sizing to contemporary PCs.
