As I understand it, Intel's strength was in manufacturing their own design in their exclusive (and most advanced) process. So the advantage was being vertically integrated. State of the art processes are too expensive these days. x86 CPUs alone cannot sustain them. Specially, when AMD builds their CPU also with state of the art processes. So by becoming a foundry, Intel may be able to have state of the art fabs and use it in their own designs of x86 CPUs, GPUs, etc.
