Key Features High-Performance Xeon 5600 and 5500 Series Processors
The x3400 M3 supports up to two high-performance Intel Xeon processors, allowing you to upgrade
to a second processor as business needs require. The x3400 M3 offers a choice of processor clock
rates, memory access speeds and power draw:

With the Xeon 5600 Series processors, Intel has diverged from its traditional Symmetric
Multiprocessing (SMP) architecture to a Non-Uniform Memory Access (NUMA) architecture. The
Xeon 5600 processors are connected through a serial coherency link called QuickPath Interconnect
(QPI). QPI is capable of 6.4, 5.86 or 4.8 GTps (gigatransfers per second), depending on the
processor model.
Six-core Xeon processors contain six complete processor cores. Processors contain one shared
12MB L3 cache. The cache is dynamically allocated between the cores as needed. The multiple
cores appear to software as multiple physical processors. Six-core processors offer considerably
higher performance than a same-speed Xeon processor with two 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
2.8GHz 6-core X5660 processor with 3-6 cores active can run the cores at 3.06GHz. With only 1or
2cores active, the same processor can run those cores at 3.2GHz. Similarly, a 2.40GHz 4-core
E5620 processor can run at 2.53GHz or even 2.66GHz. When the inactive 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.
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.
