Raspberry Pi Model B 3 Overclocking?
According to this article about the Pi 3, overclocking is not an option. Not yet at least. The Pi 3 is stuck at 1.2 Ghz for now, which should be plenty fast.

H265 decoding performance on a Pi 3
A RPI3 can decode 1080p HEVC quite well. There have been NEON optimizations to HW-accelerate HEVC decoding. Best played with KODI.
The problem is a RPI3 is running hot, so it starts throttling, an ...
