I don't think they even had the GDDR5 memory controller finalized when it was July. Whatever reason they didn't do it before, I'm very inclined to say it's technical. Otherwise even with existing GDDR4 they wouldn't have been so shortsighted with the GT200 obviously.


nVidia really did NOT knew about this one. They thought the 4870 was going to be like the 3870, excessive waste on bandwidth.

Plus they have a lot of other fish to fry too, including shader density, keeping the core clock >700Mhz, and oh wait, where's CUDA now?
