With the Xeon 5500 and 5600 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 serial coherency links called QuickPath Interconnect (QPI).
QPI is capable of 6.4, 5.6 or 4.8 GTps (gigatransfers per second), depending on the processor
model.
2-core Xeon processors contain two complete processor cores; 6-core processors, similarly,
contain six cores. Each 5600 Series processor contains one 256KB L2 cache per core and one
12MB L3 cache shared by all the cores. The shared cache is dynamically allocated between the
cores as needed. The multiple cores appear to software as multiple physical processors. The 2-
core processors offer considerably higher performance than a same-speed Xeon processor with
a single core. Likewise, 4- and 6- core processors offer considerably higher performance than a
same-speed Xeon processor with 2 cores.
Turbo Boost Technology increases performance by translating the temperature, power and
current head room into higher frequency. It will dynamically increase by 133MHz for short and
regular intervals until the upper limit is met or the maximum possible upside for the number of
active cores is reached. The maximum frequency is dependent on the number of active cores.
The amount of time the processor spends in the Turbo Boost Technology state depends on the
workload and operating environment, providing the performance you need, when and where you
need it. For example, a 3.33GHz 6-core X5680 processor with 3-6 cores active can run the cores
at 3.46GHz. With only one or two cores active, the same processor can run those cores at
3.6GHz. Similarly, a 3.46GHz 4-core X5677 processor can run at 3.6GHz or even 3.73GHz.
When the inactive cores are needed again, they are dynamically turned back on and the
processor frequency is adjusted accordingly.
In processors implementing Intel Hyper-Threading Technology, each core has two threads
capable of running an independent process. Thus, a 6-core processor can run 12 threads
concurrently.
Intelligent Power Capability powers individual processor elements on and off as needed, to
reduce power draw.
Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow
attacks when combined with a supporting operating system.
Intel’s Virtualization Technology (VT) integrates hardware-level virtualization hooks that allow
operating system vendors to better utilize the hardware for virtualization workloads.
DDR3 Memory with Chipkill ECC Protection
The x3650 M3 ships with registered double data rate III (DDR3) memory and provides Active
Memory features, including advanced Chipkill memory protection (using x4 DIMMs), for up to
16X better error correction than standard ECC memory. In addition to offering better performance
than DDR-2 or fully-buffered memory, DDR3 memory also uses less energy. DDR-2 memory
already offered up to 37% lower energy use than fully buffered memory. Now, a generation later,
DDR3 memory is even more efficient, using 22% less energy than DDR-2 memory.
