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 6.4 GTps (gigatransfers per second). Put

another way, the E7/7500/6500 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 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.

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.

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

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

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

reduce power draw.

eX5 servers use registered double data rate III (DDR3) DIMMs and provides Active Memory

features, including advanced Chipkill memory protection, for up to 16X better error correction

than standard ECC memory, IBM Memory ProteXion, and optional memory mirroring or

memory rank sparing. In addition to offering triple the memory bandwidth of registered

DDR2 or fully-buffered memory, DDR3 memory also uses less energy. 1.8V DDR2 memory

already offered up to 37% lower energy use than fully buffered memory. Now, a generation later,
