4 Processors

The Dell PowerEdge M820 features the Intel Xeon processor E5-4600 product family, 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 excel on

workloads that range from the most complicated scientific exploration to crucial web-serving and

infrastructure applications. In addition to providing raw performance gains, Intel's integrated I/O,

reduces latency by adding more lanes and doubling bandwidth. This helps to reduce network and

storage bottlenecks, unleashing the processor's performance capabilities.

The new Intel Xeon processor E5-4600 product family adds new features and improves upon many

features of the predecessor Intel Xeon processor series. A summary of what's new and improved

includes:



Up to two additional cores and up to 8MB more last level cache



More memory — 16 more DIMMs than previous-generation of full-height blade servers with

support for up to 32GB DIMMs, increasing memory capacity up to 1.5TB



Intel Integrated I/O support for up to 80 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
