This is a far more interesting design...

Essentially the system can be split to serve multiple functions.
Figure 3A defines how a system's cores and GPUs could be split to serve two primary functions, one dedicated to one function, while the other could be used for any secondary functions.
Figure 4 defines is a detailed view of the configuration of the system. Similar to the image in the OP, but much more specific and showing the split system.
Figure 5 shows a system capable of what would appear to be upgradeable memory. 5B appears to detail that system configuration in even more detail.
