Media service providers require transcode solutions with cost-efficient, dense designs and sufficient performance to support real-time, multistream delivery of high-definition video. A data center graphics server based on the Intel® Xeon® processor E3-1200 v4 product family does just that.
Transcoding is the direct conversion of one encoding format to another, such as for movie data files. This is usually done in cases where a target device does not support the original format or resolution. Typically transcoding refers to a two-step process in which the original data is decoded to an intermediate uncompressed format, which is then encoded into the target format.

Media transcoding performance is generally measured by how many simultaneous output streams can be transcoded while maintaining a 30 frames per second frame (fps) rate.
For this comparison, a 500 frame h.264 input file with a resolution of 1920x1080 and a frame rate of 30 fps was transcoded using Intel® Media Server Studio 2015 R3 Essentials Edition software on the target device to multiple simultaneous mpeg2 output files of the same resolution. The number of streams was increased until the output frame rate dropped below 30 fps. The simultaneous real-time HD streams per rack within a given industry-standard rack is shown as a relative gain from prior generation Intel® Xeon® processor E3 v3 family with Intel® HD Graphics P4700 to E3 v4 family with Intel® Iris Pro Graphics 6300.

Benchmark results were obtained prior to implementation of recent software patches and firmware updates intended to address exploits referred to as "Spectre" and "Meltdown". Implementation of these updates may make these results inapplicable to your device or system.
Software and workloads used in performance tests may have been optimized for performance only on Intel® microprocessors. Performance tests, such as SYSmark* and MobileMark*, are measured using specific computer systems, components, software, operations, and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products. For more complete information visit http://www.intel.com.au/benchmarks.
Intel does not control or audit the design or implementation of third party benchmarks or websites referenced in this document. Intel encourages all of its customers to visit the referenced websites or others where similar performance benchmarks are reported and confirm whether the referenced benchmarks are accurate and reflect performance of systems available for purchase.
Intel® processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See https://www.intel.com.au/content/www/au/en/processors/processor-numbers.html for details.
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel® microprocessors. These optimizations include SSE2 and SSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel.
Microprocessor-dependent optimizations in this product are intended for use with Intel® microprocessors. Certain optimizations not specific to Intel® microarchitecture are reserved for Intel® microprocessors. Please refer to the applicable product user and reference guides for more information regarding the specific instruction sets covered by this notice.
