The Dell PowerEdge T420 features the Intel Xeon processor E5-2400 product family, which offersan ideal combination of performance, power efficiency, and cost. These processors providesubstantial performance and capacity for entry and mainstream workloads, as well as applicationsrequiring significant memory and I/O scalability no matter what your constraint is—floor space,power, or budget. In addition to providing raw performance gains, improved I/O is also madepossible with Intel Integrated I/O, which can reduce latency by adding more lanes and doublingbandwidth. This helps to reduce network and storage bottlenecks, unleashing the processor’sperformance capabilities.The new Intel Xeon processor E5-2400 product family provides the following features: 2-socket processor design with power and dimensions optimized for density Up to 8 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—4 additional DIMMs (up to 12 DIMM slots) and support for up to16 GB DIMMs increasing the memory capacity from 128 GB to 192 GB Integrated memory controller with 3 channels of DDR3 and 46-bit physical addressing facilitategreater memory capacity Intel Integrated I/O has support for up to 24 lanes per socket of PCIe 3.0 links (for moreinformation on PCIe lanes, see the specifications in the System features section) Faster connections throughout the system with support for DDR3 1600 MT/s memory and8.0 GT/s QPI Intel Data Direct I/O (DDIO) allows 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 High bandwidth, low latency, bidirectional ring interconnect allows faster access to the 20MBmulti-banked last level cache Intel Advanced Vector Extensions offer 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, 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 baseoperating 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 dataFor more information on the Intel Xeon processor E5-2400 product family, visit Intel.com.Table 7 lists the Intel Xeon processors supported by the PowerEdge T420.
