“The performance needs of software vary, but it’s probably not
surprising that many applications have very stringent speed
requirements. Video players are a good example: a video player is
not much use if it can only play a video at 75 percent of the
required speed.

“Other applications, such as video encoding, are lengthy
operations that are best run ‘batch’ style, where you start a job
and leave it running while you go do something else. Although these
types of applications don’t have such hard performance limits,
increasing speed will still bring benefits, such as being able to
encode more videos over a given period and being able to encode at
a higher quality in the same time…”
