For games you usually want smaller number of high performant cores than many lesser performant. Haven't done much game programming in recent years, but I still remmember the terror of programming PS3 Cell CPU.

Were the CPU cores of Cell (PPEs) hard to program? I had the impression that the difficulty of the Cell was in the need to manage the 8 SPEs, not in writing software for the Power4 core.

The 8 core Carmel CPU in Xavier is not like the SPEs in Cell.

It was hard to utilise all those cores. I am sure game architectures evolved during the years, but back then we didn't know how to split the code to optimally utilise all available resources.
