16 PowerEdge M420 Technical Guide
4 Processors
The Dell PowerEdge M420 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 datacenter infrastructures and
highly dense deployments, E5-2400 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.
Processor features
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:
 Up to eight cores per processor and 64-byte cache line size
 Intel Integrated I/O support for up to 16 lanes of PCIe 3.0, which can reduce latency
 Faster connections provided throughout the system with support for DDR3 1600MT/s memory
and 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
