Just from doing basic research, we can see that there are fundamental differences between the AMD
Dynamic Switchable technology. In regards to which one is
AMD+INTEL, the differences come down to the architecture on the actual computer:
AMD Switchable Available for the products mentioned in the first link you provided, mostly AMD+AMD build ups. Enables the computer to decide to use the discrete graphics capability when plugged into AC power, or to use the mobile processor (degraded video capabilities) when on Battery power.
AMD Dynamic Switchable Available for both AMD and Intel based products, assuming you have the AMD A APU, or the Intel processor with a supported Radeon Discrete card. The main difference here between the normal 'switchable' and the 'dynamic switchable' is that the dynamic makes it's determination not based on power consumption (persay), but on the actual application use of the A/GPU.
Meaning if you are using a video intensive application, it will be using the discrete card; if you are not using a video intensive application, it will be assigned to the integrated graphics. This happens even if you are on battery or on AC power.
The benefits of the dynamic mode allow the graphics processor to decide on the mode to use, and using the Catalyst control center, the user can also force applications to run in either mode a well. Which basically allows you to 'configure' or 'assign' applications to specific roles on the computer.
