Yes, the h.264 and hevc reference implementations are also terribly slow and alternative implementations with performance optimizations, tradeoffs and additional encoding features were developed over long time spans.
The bitstream formats provide enough flexibility for the encoders to go beyond what the reference implementation does.
Software encoders provide the best quality, hardware encoders are kind of meh but do their job in a low power envelope.
