They've already build their own ARM cpu's, they are in the TX1, Nintendo Shield for example. Their most recent Volta GPU made significant progress in terms of general purpose programmability, it gained a much more flexible memory and concurrency model compared to previous chip generations. They also partner with IBM by supporting OpenCAPI for HPC.
