Default Re: next gen kepler to support dx 11.1, also take a year to rollout all cards

The memory has to be available in the first place and that has nothing to do with ISV's, or Nvidia or AMD at all, but companies that actually design and produce it like elpida or samsung, so in this case if the GK104 has a 256 bit memory bus and is a mainstream card it'll be limited to using 8 memory modules, so they have to ask those companies if they have 512 MB GDDR 5 chips rated to run at 1.5 Ghz and can supply them in enough volume.

256MB chips obviously exist since we seem them in the HD7970 cards, but 12 are needed to make a card with 3GB onboard, and needing a 384 bit bus since each chip is has a 32 bit interface, and a pair of those are connected to each 64 bit memory controler onboard the GPU itself.....Basically is the technology out there that can allow EVGA, Asus, MSI the ability to even make a GK104 card using a non reference design with 4GB onboard in the first place?
