Kabini comes to market in the form of A6 and A4 branded APUs, and the A6 5200 that should end up 50 percent faster than Brazos 2.0. You can read all about it here.
Kabini should launch in June and the Jaguar cores that power them are ready. At some point in the future, AMD has a processor codenamed Beema that is set to replace Kabini.
From what we have learned Beema has slightly upgraded Jaguar cores, which are called Jaguar+. We expect slightly higher performance, but at this time it is not clear if Beema can make it as a 20nm part. We would not be surprised to see new integrated graphics cores upgraded from the current Radeon HD 8000 series.
AMD definitely has a good chance to make even better ultrathin and small form factor processors as Jaguar quad cores look really promising, but competing with ARM based 20nm quads next year will be challenging, at least in some market segments.
