No. Intel own their own fabrication plants, have been designing CPUs for millennia, and also produce chipsets, SSDs, and are starting to produce decent IGPs.
Apple are making custom chipsets for existing CPUs and GPUs, and getting small companies they own to design and build chips that nobody else really builds.
I would say that if Apple wanted to build their own CPUs, they would buy AMD, maybe buy a fab plant, and then would require 5-10 years to actually finish the planning, designing and all that stuff before they start producing CPUs and GPUs that were actually designed for Apple's principles, as opposed to things based off present and planned AMD products.
Basically, it would be too hard, and not even close to worth it, when Apple can get fantastic CPUs and IGPs (SSDs soon hopefully) from Intel, and GPUs from AMD or NVIDIA, while keeping their staff working on building cases, software, and the next "wow".
