Videocardz claims to have received confirmation from a credible source that NVIDIA's upcoming GeForce GTX 980 Ti graphics card will have 6GB GDDR5 memory.
The GTX 980 Ti is anticipated to be a cheaper version of the GeForce GTX Titan X, both cards share the same PCB and will probably use the same reference cooling solution. The new card reportedly features the GM200-310 GPU, whereas Titan X uses the GM200-400, but exact specifications are still unknown.
Another major difference is that there will be much more custom versions of the GeForce GTX 980 Ti.
We are aware of few GTX 980 Ti models already. We can tell you to expect a full variety of coolers: reference, custom-air-cooled, watercooled and hybrids.
We can also confirm that GTX 980 Ti will have five display outputs: three DisplayPorts, HDMI and DVI-I, so same as TITAN X. We were unable to confirm the existence of ‘metal enhanced edition’, so I wouldn’t probably pay too much attention to this rumor.
What still remains unconfirmed are the specifications. Although everyone is confident GTX 980 Ti has full GM200 silicon, we cannot confirm this to you just yet. We can however confirm, that GeForce GTX 980 Ti will sport GM200-310 GPU. How does it differ from GM200-400? We don’t know (yet).
