This is what makes IFS so difficult. There aren't many whale fabless companies who can allow leading-edge foundries burn more money. Apple, NVIDIA, Qualcomm, AMD...etc. For IFS, Intel design team is one of the 'hidden' whale who made them alive. In some ways, Intel design team is financing IFS till they are healthy again. This is the reason why TSMC wafer agreement happened. Intel products needs to be competitive to finance IFS.
But IFS still has long way to go. Sadly, most of fabless customers are mobile(smartphone...etc) customers. 1.2+billion mobile devices sold per year. But IFS is not designed to 'mobile first' because Intel products team is HPC by nature(CPUs). But HPC whales aren't really fond of IFS. Both Apple and AMD(who's behind the mirror) have no reason to go for IFS. NVIDIA, maybe. But they shouldn't risk breaking their business by changing foundry when they have +70% of gross margin product. I think this is part of reason why we're not able to see IFS revenue till 2027. Focusing on large mobile market hurts current Intel products so mobile derivative comes later.
While their innovation go on, market situation got worse. There wasn't any 'PC market boom' during 2021~2024. Intel still needs additional 8B funding to fuel IDM 2.0 every year, so a few bilillion products revenue decrease mean them a lot, large enough to consider stopping construction, IFS spin-out and less snacks for employees. It might work, If they successfully finance IFS by enlisting IFS to nasdaq(wherever) enough to keep them alive till 2027~2028 timeline. If not, it still might allow Intel live as 'old, whale fabless' which somehow makes people nostalgic about good "Moore the better" days. Intel we knew gone forever in that case.
