* 'pixel throughput’ means the total amount of video content that can be processed on a core or group of cores: so a single core with 1080p60 capability could be made up by two 1080p30 video streams, or four 720p30 streams, etc. The streams can be handled independently, so can encode or decode any codecs supported.

Building on the strong momentum and expertise of ARM Mali’s graphics solutions, the Mali-V500 offers a scalable, secure solution to the video processor market capable of 4k resolution at 120fps on eight cores; thanks to this “trick-play,” video edit and slow motion capture in HD is therefore possible. With a single core, the Mali-V500 is capable of bringing 1080p60 performance to mass-market smartphones, meeting growing consumer expectations and changing video consumption patterns. The design is capable of managing multiple, simultaneous encode and decode HD streams and through this can support multi-party video conferencing and advanced user interfacing.
The Mali-V500 incorporates a novel lossless frame compression technique, ARM Frame Buffer Compression (AFBC). By coupling AFBC in the Mali-V500 with AFBC in either the display controller or Mali GPU a bandwidth saving of over 50% is achievable. This delivers a considerable system-wide power reduction, potentially allowing the use of lower cost DDR memory.
ARM always takes a system-wide approach to security starting with the deepest levels of hardware and software. In accordance with these values, the Mali-V500 was architected with support for TrustZone® enabling hardware-backed content security from download to display. As high value movie and TV content is consumed across a wider range of devices, creators and distributors of this content are looking for greater protection of their investments and all ARM video solutions will meet these demands.
For use cases such as gaming on Wi-Fi display it is important to users that latency from mobile device to display is as low as possible, at least <100ms in order to maintain an engaging experience. The Mali-V500 boasts latency of <10ms at 1080p30 for both encode and decode making gaming on Wi-Fi display a compelling experience.
Whether we are talking about graphics or video processing, visual quality is extremely important and Mali-V500 includes high bus latency tolerance whereby video processing can continue for over 5000 cycles without external memory access. This feature ensures that consumers will not see jerky playback due to dropped frames when other processes are happening on the device
