136 shader ops per cycle (RSX) vs 96 shader ops per cycle (Xenos, flexible). I will take the RSX despite not being as flexible. Of course it would be better if the RSX had flexible shaders, but the Xenos with its flexible shaders is not better with regard to potentials at all.
IMO the RSX has been well designed to fit the PS3 architecture, designed to take advantage of Cell strongpoints (Cell and RSX communication), large enough cache to take advantage of twice the bandwidth (compared to the 360) by using XDR and GDDR3 simultaneously.
