On the PS4 it was announced (I think) that they were using strictly GDDR5, which in my head is a kind of a bad thing to do. While GDDR-type is great for graphics cards, the high latencies on GDDR-types are undesirable for running an OS.
IMO the optimal configuration would probably be somewhere between the two systems. 8GB for the OS and multi-taskings, and a solid 2GB of GDDR5 for the graphics processor.

In both systems the GPU and the CPU are combined into one processor allowing the GPU to do non-graphical processes when needed (this was shown off during the PS4 reveal). In this scenario, the higher speed of GDDR5 is more desirable.
As for splitting the ram, one of the biggest things both systems are doing this generation is unified memory. Parts of the ram will be reserved for the OS but everything else is open to whatever needs it. This is one aspect the Devs really love and was one of the biggest complaints of the last generation. Having two types of ram means no more unified ram and it requires a new memory controller raising the price.
