AMD A6-3650 Llano APU Performance Review

HD Media Playback and Encoding

On the video decode side of the equation, we viewed an assortment of HD movie trailer clips and monitored CPU utilization. With a relatively powerful chip like the AMD A6-3650, we didn't expect HD video playback to be an issue but regardless, we looked at CPU utilization playing back 1080p Flash video. We also fired up an I am Legend movie trailer .mov file with Windows Media Player, and used PowerDVD to play other various formats, while taking note of thread activity in Windows Task Manager Performance Monitor.

All of the video clips we played back worked flawlessly and exhibited very low CPU utilization in the single-digits or low double-digits. Full-screen 1080p Flash video is notorious for high CPU utilization when using older drivers or Flash Players, but the situation looks good today. All of the platforms represented here performed very well in our HD Media playback tests, although AMD does offer some video enhancements that Intel does not.

HD Video Encoding Performance
Testing With and Without Intel Quick Sync

Cyberlink's Media Show Espresso is a video conversion tool that imports various video media files types and converts them to other standard video formats for publication, distribution and / or streaming. In this test, we take a 184MB high definition 1080p AVCHD video clip and compress and convert it to a iPhone 4 H.264-encoded .MP4 file. Times are measured in minutes:seconds with lower times representing faster throughput in the video conversion process.

The A-Series APUs got clobbered in our MediaShow Espresso video encoding benchmarks. Notice, performance is lower with GPU acceleration enabled, versus encoding on the CPU cores alone.
