Processors; Processor Features - Dell PowerEdge M420 Technical Manual

4 Processors

The Dell PowerEdge M420 system features the Intel Xeon processor E5-2400 and E5-2400 v2
product families, which offer an ideal combination of performance, power efficiency and cost.
Featuring 10-core processing to maximize performance and performance per watt for datacenter
infrastructures and highly dense deployments, E5-2400 v2 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 Intel Xeon processor E5-2400 v2 product family is designed specifically for servers and
workstation applications. A summary of what's new and improved includes:

Up to 10 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
