My understanding is that a long pipeline is only a benefit if the CPU gets fast enough to consume from that pipeline. CPUs around 2005-2010 had long pipelines in anticipation of higher CPU speeds which never happened. More recently, Intel have gone back to simpler pipeline design and focused on other areas.

But what's interesting to note is that the number of pipeline stages hasn't increased all that much over the years, so I wonder if the upper limit on clock speed (disregarding power dissipation) has increased mainly due to smaller process sizes.
