15 PowerEdge M520 Technical GuideThe Dell PowerEdge M520 system features the Intel Xeon processor E5-2400 product family,offering an ideal combination of performance, power efficiency, and cost, featuring eight-coreprocessing to maximize performance and performance/watt for data center infrastructures andhighly dense deployments. These processors provide high performance no matter what yourconstraint is—floor space, power, or budget—and on workloads that range from the mostcomplicated scientific exploration to crucial web-serving and infrastructure applications. In additionto providing raw performance gains, improved I/O is also made possible with Intel Integrated I/O,which can reduce latency by adding more lanes and doubling bandwidth. This helps to reducenetwork and storage bottlenecks, unleashing the processor’s performance capabilities.The new Intel Xeon processor E5-2400 product family is designed specifically for servers andworkstation applications. A summary of what’s new and improved includes the following: Up to eight cores per processor and 64-byte cache line size Intel Integrated I/O has support for up to 24 lanes of PCIe 3.0, which can reduce latency Faster connections are provided throughout the system with support for DDR3 1600 MT/smemory and up to 8.0 GT/s QPI Intel DDIO allows I/O traffic to skip the main system memory and be directed straight to theprocessor cache, which can provide a significant reduction in latency as well as allowingmemory to remain in a low-power state Intel Advanced Vector Extensions offer up to double the floating-point operations per clockcycle by doubling the length of registers, which can be useful for addressing very complexproblems or dealing with large-number calculations that are integral to many technical, financial,and scientific computing problems Intel Turbo Boost Technology 2.0 delivers up to double the boost than theprevious-generation turbo technology Continued improvements to both Intel TXT and AES-NI help to better protect systems and data Enhanced Intel Speed Step® TechnologyFor more information on the Intel Xeon processor E5-2400 product family, visit Intel.com.
