"And this is why in coherent cpu read mode is 30gb's. cos when coherent memory reads are happening in the Dram cntr they can do 4 passes . But at half speeds of max Bandwidth." -misterxmedia

I got some news for you buddy, the xbox one doesn't have hUMA. Why is there no bus like the onion in the PS4 to directly link the caches together to snoop each other ?

Do you see that block marked "cpu-cache-coherent memory access"?

I think you misunderstand what that actually means, it actually means that the CPU cores are cache coherent not the whole cache of the APU which would mean there is no bus between the GPU cache and the cpu cache.
