Well, since I am a fanboy of the Cell processor I thought I would share an interesting slide presentation from a recent IBM event. Of interest is that we all know that Cell's single precision floating-point performance beats pretty much anything that is out right now, but what IBM is planning to improve upon by 2008 is Cells double precision floating-point performance to new levels which would make Cell even more general computing friendly.
