Pretty much any CPU released in the past decade should be capable of decoding 1080P video as well as a GPU (though yes, will use slightly more power). The point is that modern GPUs have hardware decoding for common codecs, and will use far less power than CPU decoding. But the major browsers on Linux (Firefox and Chrome) disable hardware decoding on Linux, because $PROBLEMS. So, you end up with battery draining CPU-based 1080p decoding. And even more battery draining or choppy 4k decoding.
