Previous generations of embedded Intel® processors may not be supported by Intel. Refer to the comprehensive embedded processor and chipset roadmap for products backed by Intel’s 7-year extended lifecycle support.
OVERVIEW
Many storage, networking, and embedded applications require fast I/O throughput for optimal performance. Intel® I/O processors allow servers, workstations and storage subsystems to transfer data faster, reduce communication bottlenecks, and improve overall system performance by offloading I/O processing functions from the host CPU.
The table below provides a quick overview of the Intel I/O processor family. The Intel® IOP34x family of processors, with Intel XScale® microarchitecture, builds on more than a decade of leadership in I/O processor technology.

ΔIntel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See http://www.intel.com/products/processor_number for details.
Execute Disable Bit requires an Execute Disable Bit enabled system. Check with your PC manufacturer to determine whether your system delivers this functionality. For more information, visit http://www.intel.com/technology/xdbit/index.htm.
Intel® Hyper-Threading Technology requires an Intel® HT Technology enabled system, check with your PC manufacturer. Performance will vary depending on the specific hardware and software used. Not available on Intel® Core™ i5-750. For more information including details on which processors support HT Technology, visit http://www.intel.com/info/hyperthreading. Must include "chipset" on i3 or lower.
Intel® vPro™ Technology is sophisticated and requires setup and activation. Availability of features and results will depend upon the setup and configuration of your hardware, software and IT environment. To learn more visit: /Link.aspx?id=5121.
Intel® Active Management Technology requires activation and a system with a corporate network connection, an Intel® AMT-enabled chipset, network hardware and software. For notebooks, Intel® AMT may be unavailable or limited over a host OS-based VPN, when connecting wirelessly, on battery power, sleeping, hibernating or powered off. Results dependent upon hardware, setup & configuration. For more information, visit http://www.intel.com/technology/platform-technology/intel-amt.
Intel® Anti-Theft Technology requires an enabled chipset, BIOS, firmware and software and a subscription with a capable Service Provider. No system can provide absolute security under all conditions. Consult your system manufacturer and Service Provider for availability and functionality. Intel assumes no liability for lost or stolen data and/or systems or any other damages resulting thereof. For more information, visit http://www.intel.com/go/anti-theft.
Intel® High Definition Audio requires an Intel® HD Audio enabled system. Consult your PC manufacturer for more information. Sound quality will depend on equipment and actual implementation. For more information about Intel® HD Audio, refer to http://www.intel.com/design/chipsets/hdaudio.htm.
Intel® 64 architecture requires a system with a 64-bit enabled processor, chipset, BIOS and software. Performance will vary depending on the specific hardware and software you use. Consult your PC manufacturer for more information. For more information, visit http://www.intel.com/info/em64t.
Intel® Stable Image Platform Program (SIPP). Consult your PC manufacturer for availability of systems that meet Intel SIPP guidelines. Intel SIPP is a client program only and does not apply to servers or Intel-based handhelds and/or handsets. For more information, visit http://www.intel.com/itcenter/topics/refresh/sipp.htm.
Intel® Trusted Execution Technology (Intel® TXT) requires a computer system with Intel® Virtualization Technology, an Intel® TXT-enabled processor, chipset, BIOS, Authenticated Code Modules and an Intel® TXT-compatible measured launched environment (MLE). Intel® TXT also requires the system to contain a TPM v1.s. For more information, visit http://www.intel.com/technology/security.
Intel® Virtualization Technology requires a computer system with an enabled Intel® processor, BIOS, virtual machine monitor (VMM). Functionality, performance or other benefits will vary depending on hardware and software configurations. Software applications may not be compatible with all operating systems. Consult your PC manufacturer. For more information, visit http://www.intel.com/go/virtualization.
Intel® Turbo Boost Technology requires a system with Intel® Turbo Boost Technology capability. Consult your PC manufacturer. Performance varies depending on hardware, software and system configuration. For more information, visit http://www.intel.com/technology/turboboost.
