The new parts are the A4-5050 and the E1-2150. These appear to be bumped up parts with somewhat higher frequencies – other than that they don’t appear to bring anything new to the table.
The A4-5050 is a quad-core clocked at 1.55GHz with 2MB of L2 cache and HD 8330 graphics. The TDP is 13.5W, reports CPU World. http://www.cpu-world.com/news_2014/2014020401_AMD_E1-2150_and_A4-5050_Kabini_APUs_spotted.html
The E1-2150 is a dual-core clocked at 1.05GHz. It has 1MB of cache and HD 8210 graphics. No word on TDP.
It appears that the A4-5050 is an HP OEM-only chip, while the E1-2150 is not.
