HP Visualize Personal Workstations were Intel-based computers for Windows NT, released in 1999. With P-Class, HP complemented its PA-RISC Visualize Unix workstations. Systems A5015A from P450 to P700C were entry-level HP NT workstations, followed by X-Class.

Based on Intel Pentium III processors up to two-way SMP capable and with Intel 440BX chipset, the P-Class started with P450, P500 and P600 using Katmai processors, updated later in P600C, P650C and P700C with Coppermine CPUs.

They were dedicated professional graphics workstations for 3D design, CAD and CAM on Windows NT, used for professional digital content creation.

Visualize P-Class shared almost nothing with the PA-RISC based Visualize brethren but the Visualize graphics adapters, which they use in modified + Versions on AGP. They also were shipped with 3rd-party graphics such as Elsa Gloria Synergy II and 3Dlabs Oxygen GVX-1.

The dark-grey mini-tower HP P-Class used was similar to PA-RISC HP Visualize B1000, C3000, C3600, C3700 workstations and apparently the same to lower-end HP Kayak PCs.

P450 to P600 use Pentium III Katmai processors with 512 KB L2 cache on half-frequency back-side bus (BSB). P600C to P700C use Pentium III Coppermine with integrated 256 KB L2 on full-frequency.

CPUs are installed in SECC(2) cartridges in two Slot 1 slots. CPU frequencies are hard-coded but can be selected with switches 3, 4 and 5. VRMs required might be 0950-2837 and/or 0950-3310.

There is an LCD panel on the front of the case which shows BIOS and configuration info and possible detected errors by the BIOS, enhanced by beeps. The LCD can also be used for diagnostics.

Benchmarks

No official SPECint or fp results could be found for HP Visualize P-Class, so the results are based on comparble Intel Pentium III and BX reference data.
