According to Golem.de AMD is planning higher frequencies compared with Carrizo.
Apparently the notebook chips will compete in 35-watt-segment with a base clock of 3 GHz. The fastest Carrizo however, runs at 2.1GHz plus Turbo.
The upcoming chips are soldered on the new BGA socket FP4. AMD has the power management revised. Bristol Ridge has also improved the video block and the cache.
This information appears to be coming from the same source which gave us this story yesterday which means that while AMD might be boosting clock-speed the whole idea is being killed off by the OEMS who are hoping to make a quick buck. It means that we are unlikely to see much of the performance improvements that Bristol Ridge could give us.
