Key Features
Multicore Xeon Processors
The x3850 X5 and x3950 X5 ship with two high-performance Intel Xeon 7500 series
processors, and support up to four per chassis (node), allowing you to upgrade as business
needs require. The eX5 servers also go a step further by allowing you to add a second node to
increase the number of sockets from four to eight (using two chassis).

This processor is limited to single-chassis configurations (4 sockets per chassis supported).
With the Xeon 7500 series processors, Intel has diverged from its traditional Symmetric
Multiprocessing (SMP) architecture to a Non-Uniform Memory Access (NUMA) architecture. The
Xeon 7500 processors are connected through three serial coherency links called QuickPath
Interconnect (QPI). QPI is capable of 6.4GTps (gigatransfers per second). Put another way, the
7500 series processors offer 3X the bandwidth of the previous 7400 series processors.

Turbo Boost Technology
dynamically turns off unused processor cores and increases the
clock speed of the cores in use, by up to two model frequencies. For example, with six cores
active, a 2.26GHz X7560 8-core processor can run the cores at 2.53GHz. With only three or four
cores active, the same processor can run those cores at 2.67GHz. When the cores are needed
again, they are dynamically turned back on and the processor frequency is adjusted accordingly.

Each processor includes two integrated memory controllers, to reduce memory bottlenecks and
improve performance. Memory access is at up to 1066MHz frequency, depending on the
processor model and memory used.

In processors implementing Hyper-Threading Technology, each core has two threads capable
of running an independent process. Thus, an 8-core processor can run 16 threads concurrently.
