That's the big mystery question... How do they solve the bandwidth needs.
I somehow thrust the ATI engineers that they made sure that that's ok.

Maybe on a part of the die which hasn't been shown in public yet. or
maybe in cooperation with the DRAM industry + rival NVidia. It's possible
to put main memory in GDDR5 using TSV (Through Silicon Via's) die stacks.
Elpida is already supplying DDR3 TSV die stacks with 8 memory chips in a
package. The 9th chip is the interface chip which can in principle be
replaced by a GDDR5 interface chip.
