If anything, that may be an indicator that maybe nobody cares that much about
Intel's SIMD instructions.  It's not hard to see why.

SIMD instructions do not translate to a tangible benefit for the average
consumer of Intel chips. (Marketing 101: features need to connect with
benefits!)

There was a time when games and video playback stretched the ability of the CPU
to the core, and hardware for accelerating them was next to nonexistent.  The
processing-intensive tasks in those kinds of applications are handled by
dedicated hardware these days.

SIMD will not fix the major, user-visible performance issues in a Wintel PC,
like long boot times, or browsers becoming unresponsive for seconds at a time.
