Processor; Processor Features - Dell PowerEdge R320 Technical Manual

4 Processor

The Dell PowerEdge R320 features a variety of Intel processor options. The Intel Xeon processor
E5-2400 and E5-2400 v2 product families offer an ideal combination of performance, dependability
and cost. These processors provide substantial performance and capacity for entry and mainstream
workloads. 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.
In addition to the Intel Xeon processor E5-2400 and E5-2400 v2 product families, the R320
supports the Intel Xeon E5-1410, which provides a balance of performance, value, and advanced
features, and the Intel Pentium processor 1400 product family, which is cost-efficient and provides
the basic features.

Processor features

The new Intel processors provide the following features:
 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 — up to six DIMM slots and support for up to 32GB DIMMs, increasing

the memory capacity from 32GB to 192GB

Integrated memory controller with three channels of DDR3 and 46-bit physical addressing
facilitate greater memory capacity

Up to 24 PCIe 3.0 links capable of 8.0GT/s
 Faster connections throughout the system with support for up to 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 up to 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
