  How fast does iMessage image decoding need to be? And I mean this extremely rhetorically. The software launched along with the iPhone 4S. Going by geekbench, that CPU was 20-30 times weaker than a modern iPhone on a per-core basis. I know the screens on the new phones are 5x bigger, but there is plenty of room for that sandbox.
