r9 6990 vs r9 280x

post #1 of 6
Thread Starter 
i know 280x is newer, but which is faster?

They are about the same. The 6990 will probably pull ahead when the game supports CFX and VRAM is not an issue, but otherwise the 7970 is going to be better.

It doesn't have 4GB usable. It has 2GB per GPU(dual GPU card). While it has a total of 4GB, VRAM is mirrored not added together.

For example if you had 2 7970s in CFX you would have 3GB of usable VRAM, not 6GB.

The same thing is happening on the 6990 but just on a single PCB.

If you are wondering what to get, go for a used 290x... Not all games have Crossfire profiles and the scaling is not really good on most of them. A single more powerful card is always the best choice over 2x weaker ones, especially a Caymans that are 5 years old already.
