Its seems Micron may be the slowest to market with an expected Q2 2004 general availability in volume. Hynix are thought to be ahead - but I am unsure if they have sufficient volume for a NV40 or more likely R420 version to appear with GDDR3.
I understand GDDR3 offers about twice the bandwidth of GDDR2 and consumes much less power - possibly meaning you don't need and external power connector for these cards. So if you're designing a high end card - you are probably extremely interested during your design phase will you have a memory system that can reliably deliver 40GB/sec or closer to 80GB/sec. Not knowing which one you have to play with could make your design choices to hit a balanced design alot tougher. Does anyone have more insights on this matter?
Secondly does anyone have news/insights on whether we could expect to see GDDR3 appearing on the next round of top end videocards or will they come out 6 months later?
