4 Processors

The Dell PowerEdge M520 system features the Intel Xeon processor E5-2400 product family, which

offers an ideal combination of performance, power efficiency and cost. Featuring eight-core

processing to maximize performance and performance per watt for data center infrastructures and

highly dense deployments, E5-2400 processors provide high performance no matter your

constraint — floor space, power, or budget—and handle workloads that range from the most

complicated scientific exploration to crucial web-serving and infrastructure applications. In addition

to providing raw performance gains, Intel's integrated I/O can reduce latency by adding more lanes

and doubling bandwidth, which helps to reduce network and storage bottlenecks and unleash the

processor's performance capabilities.

The new Intel Xeon processor E5-2400 product family is designed specifically for servers and

workstation 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 supporting up to 24 lanes of PCIe 3.0, which can reduce latency



Faster connections provided throughout the system with support for DDR3 1600 MT/s memory

and up to 8.0GT/s QPI



Intel Data Direct I/O (DDIO) allowing I/O traffic to skip the main system memory and be directed

straight to the processor cache, which can provide a significant reduction in latency as well as

allowing memory to remain in a low-power state



Intel Advanced Vector Extensions offering up to double the floating-point operations per clock

cycle by doubling the length of registers, which can be useful for addressing very complex

problems or dealing with large-number calculations that are integral to many technical, financial,

and scientific computing problems



Intel Turbo Boost Technology 2.0 delivering up to double the boost of the previous-generation

turbo technology



Continued improvements to both Intel TXT and AES-NI helping to better protect systems and

data.



Enhanced Intel SpeedStep
