That's a mis-print by Newegg I'm pretty sure. That chip is only paired with GDDR. There's a GDDR3 and a GDDR5 edition. This is the former, I assume.
The problem with this card is the memory bandwidth, which is really low (28.8 GB/s). If your budget is small, this will probably do better for Dolphin, believe it or not:

It's not a good long-term investment since it's only a DX9 GPU while this is a DX11, but Dolphin doesn't require many DX11 hardware features yet. Eventually it will drop DX9, so that's something to consider too. However, by that point I don't think that 6570 will be keeping pace anymore.
