This would seem to point toward a tiered RAM configuration that acts somewhat like Apple's old Fusion Drives: On-package RAM would be reserved for rapid and frequent read/write, while the OS would page to discrete RAM for lower priority. Discrete RAM would act as a sort of middle ground between on-package RAM and paging to the SSD. Then again, maybe their in-house SSD controller is so blazing fast that the performance gains from this would, for most applications, be minimal.
