Solution Performance

Open source HEVC encoder, widely used in comms and cloud applications for video delivery. Applicatoin is sensitive to both core and memory performance and employs extreme levels of thread parallelism and optimizations.

“56% higher x265 performance, combined with higher core counts delivers 2x performance per server!”
Tom Vaughan, VP & GM, Video at MulticoreWare

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.
