We’ve managed to obtain a picture of the NVIDIA GeForce GTX 780 Ti’s PCB.
In the last picture we highlighted the parts that have changed in comparison to GeForce GTX 780 and GTX TITAN. As you can see the power section has been completely redesigned, but the number of VRM phases has not been changed.
Unfortunately I don’t have access to this board myself so I won’t go into details here. I can tell you though that GTX 780 Ti is using SkHynix H5GQ2H24AFR-R2C memory, which is clocked at 7 Gbps.
GeForce GTX 780 Ti is using GK110-425-B1 GPU, and here’s a picture of it.
