Comment Performance Race is Shifting Towards Perf. / Watt (Score 4, Insightful) 342
Even if the majority of users begin realize they have no practical use for top end CPUs with gobs processing power, everyone still benefits from higher efficiency CPUs. It reduces electric bills, simplifies cooling systems, allows for smaller form factors, etc. I think in the future the power efficiency will become more important as people start to care less about having the ultimate killer machine in terms of processing power. People are already performing actions on their mobile devices(iPhone, Blackberry, etc) which were possible only on a desktop in past years. The strict power requirements of these devices with tiny batteries will continue to demand improvements in CPU technology.
I'm waiting for the day when it is common to see completely passively cooled desktop computers, with solid state hard disks, no moving parts, sipping just a few watts of power without emitting a single sound.
