What is a good way to put this.....
Cell
IS POWER. It isn't that POWER6 will be based on Cell, Cell is based on the POWER core, it simply makes it a significantly more flexible platform to use. Cell is the platform which POWER6 will use which itself is a platform designed FOR POWER in the first place.
Look to the current design considerations that the POWER team has talked about- packaging concerns and heat(and how to utilize each processing element more effectively), clockspeed ramping and the inability of POWER to compete with the vector based super computers in terms of reaching performance potentials. These elements are the bullet list of what Cell improves on over existing POWER cores.
I think too many people are thinking of Cell in terms of the singular implementation that is going to be included in the PS3. Reducing or eliminating SIMD functional units and instead using the die space for additional POWER functional cores is easily accomplished using the Cell architecture. Cell's modularity is what makes it such a clearly logical choice for a company in IBM's position- the scalability and the communication potential(on and off die) of the design make it an excellent choice from embedded systems all the way up to BlueGene crushing next gen SuperComputers.
Cell is the logical evolution of POWER.
