The Inq reports there's a general feel of optimism and happiness about the GDDR4 standard from all key members in the memory industry.
We managed to talk to several higher positioned members of the JEDEC board and learned a great deal about current industry trends and what's happening with GDDR-4.
We managed to learn that the yield of Samsung's GDDR-4 memory at 1 GHz DDR (marketing number: 2 GHz) is almost perfect and the yields of higher clocked parts are good as well.
And when yield is perfect, you have a domino effect of price going down enough even to fit the $200 mark for the graphics boards. In short, this means that at least 1GHz GDDR-4 will be placed on major performing mainstream and on all high-end parts in 2007.
This means the bandwidth of the mainstream parts will go from 16 to 18GB/s - which is the default bandwidth of GDDR-3 memory clocked at 500-600 MHz DDR (6600GT, 7600GT, X1600...) will go to 32GB/s free of charge in the eternal 200 dollar range..
In Fall 2007 we can expect the G85 and R680 GPUs from ATI with GDDR4 memory. More info at The Inq.
