All HP Workstations can support a variety of operating systems. HP engineers work extensively with Windows and Linux operating system providers to verify top performance, flexibility, reliability, and compatibility with HP Workstations. We conduct joint engineering collaboration with industry partners long before systems are introduced. Even the most powerful computer can be handicapped by a sub-par GPU, which is why HP Z Workstations come equipped with a choice of industry-leading NVIDIA Quadro professional graphics.
