Solution Performance

Pexip Infinity* is video communications software that organizations can deploy across their IT infrastructure, in a public or private cloud or any hybrid combination – so that every individual can have their own personal high-quality video, audio and mobile meeting experience.

“The VP9 video codec with superblocks of 64 x 64 pixels is particularly well suited to the Intel AVX-512 instruction set since a 512 bit registers can hold exactly 64 pixels. At similar visual quality, our VP9 implementation is roughly 3 times faster than the LibVPX implementation that is not yet adopted to AVX512.”
Lars Petter Endresen, PhD, Principal Performance Engineer, Pexip

“The Intel® Xeon® Scalable processors with Intel® AVX-512 provides up to almost 50% performance increase for VP9 encoding and decoding [compared to previous generation Intel® Xeon® processors]. This translates to a dramatic reduction in TCO for our customers whether they deploy in an IaaS cloud or on-premises, and will enable very high quality enterprise video communication at scale.”
Håkon Dahle, CTO, Pexip

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.
