4.3 Simultaneous Multi Threading (SMT)
The Intel
®
Xeon
®
processor C5500/C3500 series supports SMT, which allows a single
core to function as two logical processors. While some execution resources such as
caches, execution units, and buses are shared, each logical processor has its own
architectural state with its own set of general-purpose registers and control registers.
This feature must be enabled via the BIOS and requires operating system support.
4.4 Intel
®
Turbo Boost Technology
Intel
®
Turbo Boost technology is a feature that allows the processor core to
opportunistically and automatically run faster than its rated operating frequency if it is
operating below power, temperature, and current limits. The result is increased
performance in multi-threaded and single threaded workloads. It must be enabled in
the BIOS for the processor to operate within specification.
