HP Z600 Workstation (ENERGY STAR)
Engineered to perform
• The HP Z600 is engineered to optimize the way processor, memory, graphics, OS, and software technology work together to deliver massive, whole-system computational power.
Sleek new industrial design
• Brushed aluminum side panels, integrated handles, and visually cable-less engineering are just a few of the new design features that create new standards for lowered acoustics, serviceability, and energy efficiency.
Designed with the environment in mind
• Lower power and cooling costs with ENERGY STAR® qualified configurations, 85% efficient power supplies, and HP WattSaver, an energy-saving feature that, when activated, helps lower energy consumption in off mode.
Revolutionary architecture
• Tackle bigger problems faster and process more tasks and threads in parallel with the new Intel® QuickPath Technology and new Intel® Xeon® processors* with integrated memory controllers.
Compact and unassuming
• Enhance your work area with HP's quietest workstation, designed for environments where space is at a premium.
Ease of service without comparison
• The tool-free chassis and the uncluttered and highly streamlined internal design gives you the ability to add or change components in mere seconds.
Easy-to-use system diagnostics tool
• Quickly capture complete system configuration data and share with IT personnel with HP Vision Field Diagnostics, an easy-to-use system diagnostics tool that runs outside the OS.
