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.
