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.

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
