Xbone CPU bandwidth 50% higher than PS4

Just to make the specs reliable both have CPU bandwidth at 30GB/s... 20GB/s is wrong.

The PS4 CPU have a link to the main memory of 20GB/s while the Onion(+) between CPU/GPU add 10GB/s... so using the two bus PS4 CPU have 30Gb/s total cache-coherent bandwidth.

The Xbone too... the diagrams shows 20.8GB/s direct link from Jaguar to memory but they stated 30GB/s because there are another bus to make the coherent-cache.

This CPU part is almost identical between PS4 and 360.

ethomaz, can you actually add those together.  Can the CPU access both bus at the same time and isn't the onion bus just between the PS4 and CPU cache.
