Processor; Processor Features - Dell PowerEdge R520 Technical Manual

4 Processor

The Dell PowerEdge R520 features the Intel Xeon processor E5-2400 and E5-2400 v2 product
families, which offer an ideal combination of performance, power efficiency and cost. 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. In addition to providing raw performance gains,
improved I/O is also made possible with Intel Integrated I/O, which can reduce latency by adding
more lanes and doubling bandwidth. This helps to reduce network and storage bottlenecks,
unleashing the processor's performance capabilities.

Processor features

The Intel Xeon processor E5-2400 and E5-2400 v2 product families offer the following features:

2-socket processor design with power and dimensions optimized for density

Up to ten execution cores per processor

Intel Hyper-Threading technology enables up to 16 computational threads

Micro-architecture on 32nm process for greater performance per watt

Support for more memory — four additional DIMMs (up to 12 DIMM slots) and support for up to
32GB DIMMs increasing the memory capacity from 128GB to 384GB

Integrated memory controller with three channels of DDR3 and 46-bit physical addressing
facilitate greater memory capacity

Intel Integrated I/O has support for up to 48 lanes (24 lanes per socket) of PCIe 3.0 links capable
of 8.0GT/s
Faster connections throughout the system with support for DDR3 1600MT/s memory and

8.0GT/s QPI

Intel Data Direct I/O (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

High bandwidth, low latency, bidirectional ring interconnect allows faster access to the 20MB
multi-banked last level cache

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, which are integral to many technical,
financial and scientific computing problems

Intel Turbo Boost Technology 2.0, which allows processor cores to run faster than the base
operating frequency if it's operating below power, current and temperature specification limits,
delivers up to double the boost than the previous generation

Continued improvements to both Intel TXT and AES-NI help to better protect systems and data
