trying to buy r9 280x graphics card and have a question.
One card says 256bit the other says 384bit. Does this refer to the data transfer rate within the card or to a transfer rate to the motherboard? If it's just within the card I don't have to worry about compatibility to my MoBo.
Thanks

The 384-bit is much, much faster.

Thanks but do I need to worry about compatibility to MoBo?
I have an older r9 280x vapor-x that I bought last year and I assume it's something less than 384-bit.

Howdy Merle,
That refers to the "Memory Bus Width" of the card.
It won't affect motherboard compatibility.
As far as I know - ALL 280X's are 384bit.
the slower 270X is 256bit.
also - the older 7970 gigahertz edition is basically
the same as the 280X. (they just re-named it )

Bill is right. In addition:

Bill is right. In addition: the 256 bit card you saw may have been a R9 285 based on the Tonga GPU. It's got the smaller memory bus and fewer shaders, so it's in every crunching-related aspect worse than a R9 280X. Even the R9 280 probably performs better at Einstein, as it still has the 384 bit bus.
