Our friends over Techpowerup have taken a picture showing the PCB of the upcoming GTX 1080 Ti from NVIDIA. For comparison, they’ve put the naked GeForce GTX 1080 Ti next to the TITAN X Pascal, which clearly shows that those two cards are very similar.


As you can see, the GeForce GTX 1080 Ti is based on the same PCB like the TITAN X Pascal and both cards feature the same "GP102" chip (with different core configurations). Browsing the specifications of the GP102 chip we find a whopping 3584 CUDA cores, 224 TMUs and 88 ROPs. For comparison reasons, the TITAN X Pascal features 3584 CUDA cores, 224 TMUs and 96 ROPs. However there are a few small differences visible on the PCB. First of all the GTX 1080 Ti features 11 memory chips compared to the 12 we can find on the TITAN X Pascal graphics card. Nevertheless the GTX 1080 Ti offers more memory bandwidth thanks to the GDDR5X memory clocking at 11 Gbps while on the Titan X Pascal’s memory is set to run at 10 Gbps.

The main difference between the GTX 1080 Ti and TITAN X Pascal is the VRM area since there are two dual-FET MOSFETs. NVIDIA basically added an additional set of MOSFETs and capacitors along all the blank traces of the reference PCB. This approach lowers the load on each individual MOSFET and as a result temperatures are lower as well. According to Techpowerup, this change might enable a higher power-limit. NVIDIA also updated the I/O ports sacrificing the DVI connector. This way the cooler can now push air through the entire width of the second slot in the card's I/O shield.
