The name of the APU is linked to in my last post.
It is called the FX-7600P and is the first FX branded laptop APU.
It basically is a downclocked A10 7850K running at a 35W TDP instead of a 95W TDP,with 2.7GHZ to 3.6GHZ core clockspeed instead of 3.7GHZ to 4.0GHZ and a 512 shader IGP running at 600 to 666MHZ instead of 720MHZ.
However,ther FX-7600P can also use 2133MHZ DDR3 RAM,so it should not be far off an A10 7850K in lightly thread and IGP performance. The previous highest end AMD mobile CPU,the A10 5750M,had much lower clockspeeds for the IGP relative to the desktop version,so with the faster RAM,the IGP performance should be much better overall.
Over on overclock.net there are suggestions that HBM might be used,but I think it is unlikely IMHO.
