Title: Difference between 192-bit and 320-bit GDDR5?
Post by: G_G on August 17, 2012, 09:03:24 am
I found two nVidia powered graphics cards, manufactured both by EVGA. One has 192-bit RAM and the other 320-bit. I'm curious to know if there's any real performance difference here. Any input would be nice as to which card I should get as well.

The cards I was looking at.

EDIT: A friend already answered my question.

Quote"In all reality, the bit count that they are referring to is the number of binary digits that the card reads per line of machine ISA code. Generally, having more bits is better, but you probably won't ever know the difference in use between the two."


With that answer, it'd be more logical to get the 320-bit one, but the 192-bit one comes with a free copy of Borderlands 2. Thus I'm getting that. ^3^

He's right, the difference is insignificant. Imagine the difference between a 32-bit CPU and a 64-bit CPU, it's insignificant in terms of machine code lines.
