Real question. Wouldn’t a video editor lean on GPU ?

  There's no general answer to that. For example the MPU could have a set of vector operations that use a special range of memory not mapped by the cache and that has its own path to the MPU. Those instructions could conceivably be faster (or have a different power profile) than GPU for certain tasks. I say "MPU" rather than "CPU" because I think of the CPU in a more traditional sense (ALU+register sets) while I think of system design as encompassing a whole range of functional elements which can include computational, memory, etc. Even within the CPU these days you'll find very complex behavior including speculative execution, various shadow registers and register windows etc.
