AMD is kicking off 2019 with an overhaul of its laptop processors, and it's breaking some new ground in the process. The company has unveiled its first two A-Series chips designed explicitly for Chromebooks, the 1.6GHz A4-9120C and 1.8GHz A6-9220C. Both are dual-core chips that use just 6W of power and promise faster performance than the Intel chips you typically see in entry-level Chrome OS portables. The A6 is up to 23 percent faster in web browsing than the Pentium N4200, AMD said, and 42 percent faster in photo editing. You might not have to spend a small fortune to get a Chromebook with decent horsepower.
