SIMD isn’t the “end all”, but upcoming Intel chips have instructions for handling 8 doubles or 16 floats per instruction, and if you’re trying to implement a video codec or large-scale physics simulation, an order of magnitude of speed difference can make or break your app.
To take an example where timeliness is crucial, think of the difference between, say, 10 frames per second vs. 60 frames per second in a first-person shooter game.
