exists.

With the Xeon E7 family and 7500/6500 series processors, Intel has diverged from its traditional

Symmetric Multiprocessing (SMP) architecture to a Non-Uniform Memory Access (NUMA)

architecture. The processors are connected through three serial coherency links called

QuickPath Interconnect (QPI). QPI is capable of up to 6.4GTps (gigatransfers per second),

depending on the processor model.

The 4-core Xeon processors contain 4 complete processor cores and 8 threads. Each

processor contains one L3 cache, shared by all the cores. The cores appear to software as

separate physical processors. Four-core processors can offer more than double the performance

of a same-speed 2-core Xeon processor (depending on workload). Similarly, 8-core Xeon

processors contain 8 processor cores and 16 threads. They can offer more than double the

performance of four-core Xeon processors (again, depending on workload). Likewise, the six-

core processors contain six processor cores.

Each processor includes two integrated memory controllers, to reduce memory bottlenecks and

improve performance.

Turbo Boost Technology dynamically turns off unused processor cores and increases the clock

speed of the cores in use, by up to three model frequencies. For example, with 7-10 cores active,

a 2.4GHz E7-2870 10-core processor can run the cores at up to 2.53GHz. With 5-6 cores active,

it can run those cores at 2.67GHz; with only 1-4 cores active, it can run those cores at 2.8GHz

Similarly, with six cores active, a 2.26GHz X7560 8-core processor can run the cores at

2.53GHz. With only 3-4 cores active, it 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.

Intelligent Power Capability powers individual processor elements on and off as needed, to

reduce power draw.

Intel’s Virtualization Technology (VT) integrates hardware-level virtualization hooks that allow

operating system vendors to better utilize the hardware for virtualization workloads.

The HX5 uses registered double data rate III (DDR3) VLP (very-low-profile) DIMMs and provides

Active Memory features, including advanced Chipkill memory protection, for up to 16X better

error correction than standard ECC memory. In addition to offering triple the memory

bandwidth of DDR2 or fully-buffered memory, DDR3 memory also uses less energy. DDR2
