Now we know that the 32MB ESRAM in XBone is divided into 4 banks of 8MB each, its 109GB/s min and 204GB/s peak... is not what it says in SoC components ? (2 image)
So all in all, XBone has more "peak" bandwidth than PS4 for the GPU. Doesn't make "that difference" because its only 32MB, 8GB GDDR5 will still be better for games, but the difference might be shorter than many think.
the second slide shows that the DRAM is off the die. iirc a teardown shows that the memory module is seperate on the pcb. why do you keep calling it ESRAM? if it's static ram, won't be on the die?
No.. from http://semiaccurate.com/2013/08/26/xbox-one-details-in-pictures/ 2th image... on the bottom of that image,
"inside" the rectangle that represents the SoC chip, there are represented 4 8MB smaller squares, that represent ESRAM.... 32MB (4x8), and its clearly on die.
Seems 100% on the "mouche"...

[ UPDATE: and S|A is late if "~correct" rumor is concerned. One thing that seems to detach is the effective issue power... Durango is a 1.2+TFLOPS GPU, that can address each SIMD core separately, it can issue 768 threads per second without too much entanglements with wavefronts i think, so wasting less resources and augmenting the scheduling efficiency. ( that seems what this implies )

Don't now how that compares with PS4 efficiency... which has more sp and should be better at games, more if hUMA/HSA centered... but having 1.2+TFLOPS out of 68GB/s DRAM, to be really efficient, then ESRAM must provide a real awesome boost ]
