Intel hopes to gain a manufacturing advantage over TSMC with the upcoming 18A node, which includes new technology such as RibbonFET and backside power delivery. The technologies will make chips more efficient.
Intel is betting the farm on 18A in its transition to a manufacturing-first company. The ability to customize with chiplets and GPUs may be an advantage with 18A. Intel is hoping for a server advantage over rivals with Clearwater Forest, which will be made on 18A and ship next year.
They have an awful lot hanging on the success (even market leadership) of their 18A node.
