Same card, different memory size
« on: March 10, 2014, 06:35:52 PM »
When looking at cards I see multiple amounts of memory options for the same GPU.  For instance, in 7970 I have seen both 1GB and 3BG versions - which have a very different price (and thereby effect ROI greatly).  I know that the vast majority of the functions of a gaming GPU are irrelevant to mining and I know that the more memory a graphics card has, the higher the resolution the card can produce in a game.  I would like to know how that memory size translates to mining.  Does a 7970 (or any other card for that matter) with 1GB produce more hashes per second than a 7970 with 3GB?  Is that difference linear - does a 3GB card produce 3 times the hashes of a 1 GB card?

I hope this not a stupid question.  If it is, please humor me.   ;)

Thanks in advance for your time answering this question.

As I know it is irrelevant to mining. Cards with 1gb mostly are cheaper than 3gb versions and obviously make a bit less heat.
