You have to hand it to Intel. It just doesn't let go of a dream. Despite not being able to make a big enough dent in the smartphone market, it is still soldiering on, revising its strategy again and again. While many of us thought (or hoped) that the chip maker would just focus on wearables, it's taking another stab at smartphones, phablets, and tablets. This time with a new line of mobile chips under the names of the Atom x3, Atom x5, and Atom x7.
