Captain_Tom said: Yeah but that is still quite a bit higher than 4K and it still can't use 6GB! Also the 660 Ti uses 2GB on 192 so...
P.S. Even so that is still a sh!t ton of VRAM usage! Have fun on 2GB 680 owners! |
192 / 32 = 6
6 x GDDR5 2Gbit = 1536MB
Weird they are using four slots with 256MB and 2 slots with 2x 256MB = 2048MB... the two slots with 2x 256MB are slow than the four with one slot with 256MB.
The best way in memory performance is the GTX 660 TI with 3GB.
More weird is that the PCB have 8 slots for memory but nVidia uses only 6 slots... the PCB have a 256bits bus but nVidia choose to use a 192bits one.

PS. I made a mistake the GK110 bus is 384bits and not 320bits lol
