Intel spreads their R&D revenue across many more product categories than AMD does. In addition to CPUs, they've got their new GPU, their SSDs, their entirely new form of NVRAM, wireless networking, and many other projects. And they run their own fab, which is a huge investment that AMD doesn't have to make. AMD just makes their CPUs and GPUs. Also, Intel's CPU designs tend to be much more custom than AMDs, trading more engineering effort for a bit more performance.
