Technical analysis of Intel ($INTC)'s 18A process suggests it is a "game changer" due to the implementation of GAA RibbonFET transistors and PowerVia backside power delivery. These innovations allow for reduced leakage, higher operating frequencies, and denser chip integration by shrinking PMOS channel widths to 20–22 nm. The sentiment is highly positive, indicating these structural improvements should enable more dies per wafer and lower power consumption for Intel products.
