The red card (MSI's product name for it is "
RX9800PRO-TD128SP") is the same as the green one (MSI's product name for it is "
RX9800PRO-TD128"), albeit a little less expensive from most stores for whatever reason. Both have a 256 bit memory interface, 128 megs of RAM, and reports indicate that almost all of these cards have R360 cores and Hynix RAM.
In fact, I haven't heard of anyone who
didn't get an R360 core on their MSI 9800 Pro.
The green card has a larger Heatsink than the red one, uses a floppy power connector, and has a slightly different PCB - besides that, there's no difference between the two.

I think the Green retail version one comes with more bundled software than the red, although I'm not certain. If you go to the links above, from ZZF, there's a link on each page to MSI's detailed product specs.
