Intel (NASDAQ: INTC) recently announced it will stop investing in SoFIA, its Atom-based mobile SoCs for low-end Android devices, and Broxton, its Atom chipset for high-end smartphones and tablets. This move marks a big retreat from the mobile market, but it wasn’t surprising — Broxton was already pushed back from its original launch date last year, and certain SoFIA chips had also been delayed.
