This misses the point of where Intel is going. Intel does not see the PC market as a growth sector as a whole. It may grow for individual companies, like AMD, as they take up part of the share, however. That doesn't mean the PC market as a whole is growing. It's actually shrinking.

Intel recognizes this and is focusing on data centric use-cases like supercomputers and clouds.

For example, Intel is leading "Pathforward" with the US Government to develop very high-end solutions to large-scale problems; https://www.ecpannualmeeting.com/

In summary, Intel doesn't care that much about the PC sector because it's shrinking as a whole.
