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. 

It's DDR3... and GDDR3 have high latency than GDDR5.... what the internet uplink have to do with memory bandwidth?
