They have (still) a dominant share there and so can’t grow. Furthermore, their existing share is threatened by AMD, Apple and soon Qualcomm.
Server is another large market but growth has slowed to a more mature rate levered to GDP. Here, Intel has a large share but that share is in free fall due to Epyc and will fall further with ARM and RISC V offerings as well as custom cloud silicon. Nvidia and AMD can also undercut at the system level with GPU bundling.
No growth means no revenue to improve and expand the next generation of fabs. We all know that TSMC has the revenue growth to support their growth since they have a diversified customer base building everything - PCs, smartphones, GPU, auto etc.
Intel’s core competency is silicon manufacturing. They are right to address foundry as a business model. However, it will be extremely difficult if not impossible to unseat TSMC. Intel does not have the cash flow to justify investment in foundry, especially with no customers. They need to lean on government handouts and build out trust.
The current strategy is very flawed due to the simple conflict of interest. How can Intel justify fab for their competitors such as AMD, Apple, Nvidia and Qualcomm? Incentives are misaligned.
The only way out is for Intel to split into two independent companies.
Intel design
Intel foundry
Intel design can be free to use TSMC or Intel based on merit.
Intel foundry is free to fab for Intel-design competitors.
I firmly believe this is the actual end game and Pat is just buying time to set the stage for the split. Split too early and the design team won’t have enough time to adjust to a fabless model. Also the fabs need an interim revenue / government money stream to bootstrap into manufacturing readiness.
The plan is clear if you look at what is actually happening.
