I am also looking for Richland info, but more on the laptop side. On the laptop side, AMD has claimed large gains for the ULV parts. However, even 35W parts appear to be much improved, through both base clock speed bump and by virtue of being able to hit Turbo more often. As a datapoint, I found (via notebookcheck.net ) that A10-4600M does about 2.0 on Cinebench 11.5 multithreaded and A10-5750M (Richland) does about 2.3 which is about a 15% improvement. That is a nice improvement on the CPU side, which has been the achilles heel for Trinity.
I am on the lookout for Richland laptops. So far I have found MSI GX60 and GX70 being updated to 5750M from 4600M, and HP upgrading several Trinity offerings (such as Sleekbook) to Richland. However, i have not seen any interesting announcements from other OEMs.
