Kechichian said Intel hoped to build its new chip in-house, another move that would ultimately make it cheaper than those offered by rivals who rely on TSMC.
When you go with an AMD chip you’re paying margin to the chip designers (AMD) and margin to the fabricator (TSMC). With an Intel in-house chip you’re paying margin to Intel that incorporates both margin for the design and margin for the fabrication.
But the only way the Intel chip could be cheaper is if it’s making less margin than AMD plus TSMC. So either they’re planning on making less margin on their design services or less margin on their fabrication services or both. Taking less margin is not something you have to do when you’re making a desirable product!
