Dude you still have to shuffle stuff from much slower ram into the ESRAM and hope it can give it a nice speed boost.  The bandwidth on the 8GB acts as a massive bottleneck.

No. It doesn't.
You have this thing called "Prediction" where you predict the data you are going to require ahead of time, it's a technique which has been used to varying degree's for decades, extremely effective on fixed-hardware devices such as consoles for obvious reasons.
Converesly, both devices will be streaming a significant amount of data not from Ram, but from mechanical and optical disc storage which is stupidly slow, we saw that put to great use last generation.

The real limitation to the Xbox One is not Bandwidth, it's actually the reduced GPU resources used to draw all the pretty things on your screen.
Look at other GPU designs in the PC space as an example, AMD Fury has an abundance of bandwidth, more than any other graphics card to ever exist, more than several Geforce cards combined... Yet has minimal benefit from it. Why? Because there is not enough hardware to make use of such a wide and fast highway.

Haha that extra bandwidth IS going to use in 4K and will make a massive difference in a year or two when it is actually utilized.  Just look at the 7970 vs the 680 for an example.  At first everyone acted like the extra bandwidth in the 7970 was wasted, but once games actually started needing to feed that much information it got pathetic - so pathetic that a 7970 pretty much matches a 780 now.

Not to mention that the ESRAM isn't even much faster than the GDDR5 the PS4 is using.  Usually this special RAM is like 2-4x faster (Or more), but its not evn 50% faster.  In fact it is slower than the 10MB of ESRAM in the Xbox 360.
