For the first time, AMD has gained a little bit of traction in Chromebooks with some partner announcements at CES such as the HP Chromebook 14 AMD and the Acer Chromebook 315. The announcements are in conjunction with the new A4-9120C and its sibling, the A6-9220C, which have slower CPU and GPU clock speeds than the 15-watt full-fat versions. That allows AMD to match the 6-watt target power draw of Intel's competing Celeron and Pentium models.

AMD claims somewhat better performance on both Chrome OS and Android apps, which is possible given that their clock speeds are still faster despite the drop.
