15 PowerEdge M820 Technical Guide4 ProcessorsThe Dell PowerEdge M820 features the Intel Xeon processor E5-4600 product family, which offeran ideal combination of performance, power efficiency and cost. These processors provide highperformance no matter what your constraint is — floor space, power or budget — and excel onworkloads that range from the most complicated scientific exploration to crucial web-serving andinfrastructure 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 andstorage bottlenecks, unleashing the processor’s performance capabilities.Processor featuresThe new Intel Xeon processor E5-4600 product family adds new features and improves upon manyfeatures of the predecessor Intel Xeon processor series. A summary of what’s new and improvedincludes: 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 withsupport 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 memoryand 8.0GT/s QPI Intel Data Direct I/O (DDIO) allowing I/O traffic to skip the main system memory and be directedstraight to the processor cache, which can provide a significant reduction in latency as well asallowing memory to remain in a low-power state Intel Advanced Vector Extensions offering up to double the floating point operations per clockcycle by doubling the length of registers, which can be useful for addressing very complexproblems or dealing with large-number calculations that are integral to many technical, financialand scientific computing problems Intel Turbo Boost Technology 2.0 delivering up to double the boost of the previous-generationturbo technology Continued improvements to both Intel TXT and AES-NI helping to better protect systems anddataFor more information on the Intel Xeon processor E5-4600 product family, visit Intel.com.
