I'm looking to create a HTPC to serve media to my Chromecast, ideally using Plex. I had a play around with a RPI model B a while back and found that it didn't really have enough power to transcode video for live streaming. Has anyone had a chance to test this on the more powerful B+? I couldn't see any change in processor spec, so expecting it to be little better at best. Thanks!
The processor is the same, It's just a little lighter on power usage and a slightly diffrent layout on the board.
As Votik said, there's no difference in performance between the B and the B+. Same memory, same processor, same everything. The B+ just has a new layout, more reliable power supply and extra GPIO pins and USB ports. If you're trying to transcode, any Pi is the wrong tool for the job.
