And the fixed-function-units in Durango :)

There is more except the Data Moves engines? These exists to free up the CPU and GPU from the data moved into the memory... more like a alternative to together with eSRAM to avoid the DDR3 low bandwidth bottleneck.---Thread fixed.~tads12

It's GDDR3 memory, and GDDR3 memory has less latency than GDDR5 memory.

I can have a 100Mbps uplink to the Internet, but if my latency is 500ms, a 10Mbps connection with 10ms latency will always be faster.  The higher latency of GDDR5 memory undoes the performance the higher bandwidth offers.  By using eSRAM with GDDR3 memory, Microsoft more than makes up for the lower bandwidth.
