Hardware encoding is needed/proper for high speeds but that doesn't mean you don't need performance when doing software encoding!

The problem is such: ASICs are inherently too inflexible to achieve best (meaning best attainable, not best in theory) quality compression. They can do fast and energy-efficient but the image quality is average or more often sub-par. The reason is that they can't exploit the most of the huge search and decision tree of encoding tools + psychovisual optimization options a modern video format gives. This is something lots of people aren't aware of and it leads to all sorts of misconceptions about "GPU" (more precisely "ASIC") and hardware encoding. Or generally about video compression.

Maybe some day some breakthrough and paradigm shift will bring formats where ideal quality compression will be successfully achieved through specialised ASICs, but I don't see any path to that in the present state of this field.

So you have GPU/specialised ASIC/SoC encoding for fast and disposable encoding jobs, like encoding game footage for twitches or movies for phone and that's fine. But if you are encoding a movie to be pressed on bluray or to be distributed thousands or millions of times to end consumers over VoD web services *and you care about quality* (meaning, you don't want blurred backgrounds, banding in night battles, blocks and other artifacts and such mess), you want advanced video encoder and those are sofware, runs-on-CPU programs.
(Note: not with floating point ops, integer values and ahence integer SIMD ops are used in video).

Similarly as encoding, there is scope for software video decoding and that is also reason to have integer SIMD: because it is more flexible and you can use software decoders to decode anything, not being a slave of what your GPU's ASIC decoder can handle.

So for example with software decoding we could play VP8/VP9 some 3 years before is appeared in hardware, AV1 last year as opposed to next year (not to mention, we can keep using the same hardware and not buy new one). You can play 10-bit H.264 since 2011 while nothing supports it in hardware to this day.

Also even when you have hardware playback, it often comes with bugs and quirks that make decoding in software easier and less hassle as long as you don't hit prohibitive fan noise/power usage on a notebook.
