Hyper-threading

This HP workstation supports Hyper-threading.

Hyper-Threading Technology (HTT), is an Intel-proprietary technology used to provide process parallelization . The technology improves processor performance under certain workloads by providing useful work for execution units that would otherwise be idle. A processor with Hyper-Threading enabled is treated by the operating system as two processors instead of one. Hyper-threading relies on support in the operating system as well as the CPU.

To implement hyper-threading, see The Computer Setup (F10) Utility on page 29.

Intel Turbo Boost Technology

The HP Z Workstation series supports Intel® Turbo Boost Technology.
