System Features - Dell PowerEdge M420 Technical Manual

The Dell PowerEdge M420 system features the Intel Xeon processor E5-2400 product family,
offering an ideal combination of performance, power efficiency, and cost, featuring eight-core
processing to maximize performance and performance/watt for datacenter infrastructures and
highly dense deployments. These processors provide high performance no matter what your
constraint is—floor space, power, or budget—and on workloads that range from the most
complicated scientific exploration to crucial web-serving and infrastructure applications.
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 has support for up to 16 lanes of PCIe 3.0, which can reduce latency

Faster connections are provided throughout the system with support for DDR3 1600MT/s

memory and 8.0GT/s QPI
Intel DDIO allows 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 offer 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 delivers up to double the boost than the

previous-generation turbo technology
Continued improvements to both Intel TXT and AES-NI help to better protect systems and data

Enhanced Intel Speed Step
