Probably in the BIOS, you'll get an option for Quad Unganged or Dual Ganged. Trinity/Richland will be locked to Dual Ganged because it doesn't support Quad Unganged.
Why would 4 32-bit channels be any different than 2 64 bit channels, bandwidth wise? Also those 4 32 bit channels would be for 32 bit GDDR5 chips, not 64 bit DDR3 chips.
Kaveri might have an IMC strong enough to drive dual channel DDR3 2600 on the desktop, while 512 spus and quad channel gddr5 make pretty good sense for mobile.
Strapping 4500mhz gddr5 ram to kaveri would have something between 8770m and 8830m level performance assuming gpu clocks are the same as the last APU. Sounds like a winning idea to me.Edited by MrJava - 8/27/13 at 12:42pm
