Fusion APUs to continue to be memory speed-sensitive?

The current AMD Fusion APUs, Brazos and Llano, do provide a good balance of integrated CPU and GPU performance, although the system designers, or the PC assemblers using them, should note that there is quite high performance dependence on the memory speed used, especially for the quad-core Llano. This is expected to be even more the case for the upcoming 'Trinity' successor to Llano
