See, this is the part that everyone is missing with this release. The 1080 Ti is actually being accurately marketed thanks to the 970 fiasco. Remember that the 970 also had 8 of 64 ROPs disabled, but it was still advertised as a 64 ROP, 256-bit 4GB card when it was a 56 ROP, 224-bit 3.5GB card. If the fiasco didn't happen then NVIDIA would probably still be advertising the 1080 Ti as a 96 ROP, 384-bit 12 GB card instead of 88 ROP, 352-bit 11GB.
Come on guys!! so many years later and i keep seeing this misinformation being said, even from experienced [H] members such as Armenius (*this is what surprised me the most). There have been many articles since then, that made it clear that 970GTX had 4GB of RAM, NOT 3,5 although a 512MB segment was underperforming !!
Check the new GTX1080Ti review tom's :
( http://www.tomshardware.com/reviews/nvidia-geforce-gtx-1080-ti,4972.html ). Enough with this 3,5GB misinformation!!Losing capacity is also preferable to repeating the problem Nvidia had with GeForce GTX 970, where it removed an ROP/L2 partition, but kept the memory, causing slower access to the orphaned 512MB segment. In this case, all 11GB of GDDR5X communicates at full speed.
