Xeon™ Processor 5500 Series
What’s new about the Intel Xeon Processor 5500 Series (codenamed Nehalem)?
Integrated Memory Controller featuring QuickPath Interconnect (QPI)
QuickPath Technology means that each processor core features an integrated memory controller and high-
speed interconnect, linking processors and other components to deliver dynamically scalable interconnect
bandwidth, outstanding memory performance and flexibility, and tightly integrated interconnect reliability,
availability, and serviceability (RAS).

Turbo Boost Technology
Turbo Boost delivers additional performance automatically when needed by taking advantage of the processor's
power and thermal headroom. This enables increased performance of both multi-threaded and single-threaded
workloads.

Hyper-Threading Technology
Hyper-Threading allows thread-level parallelism on each processor resulting in more efficient use of processor
resources. With higher processing throughput, you enjoy substantially improved performance.
DDR3 Memory
The move to DDR3 memory offers increased performance due to higher memory speeds, and reduced power
consumption compared to FB-DDR2 memory operating at the same speed.
Improved Energy Efficiency
The new Intel microarchitecture allows for more efficient load and idle performance. Core states are managed in
response to demand in order to remain within the thermal envelope.
Dramatically Increased Performance
Dramatically Decreased Energy Consumption
