The top notch R700 comes with 2GB GDDR5 memory, but AMD will allow its partners to build a GDDR3 based version of the card. Such a board will be cheaper and faster to market.

This configuration will include 1GB GDDR3 memory and two RV770PRO chips and since the partners will be allowed to build these boards there might be a chance to some of the AIBs might come with its own cooling solution.

Such a board might have a chance to come in August but it looks like that this particular version might come a bit later. R700 with GDDR5 has a big chance to start shipping as early as mid-August, but a fixed date has not been picked yet.
