NVIDIA GeForce GTX 1080 Ti features GP102-350 GPU

Published: 4 months ago | Comments

A short story for today about GTX 1080 Ti.

NVIDIA Pascal GP102-350

First, let’s look at official renders released by NVIDIA. We have two pictures showing the PCB:

We managed to find more pictures confirming the exact GPU codename, which is Pascal GP102-350 GPU. First up, here’s the slide from GAINWARD confirming not only the GP102 variant, but also base and boost clocks. In fact, they were posted by pretty much all AIBs shortly after the announcement, so there’s no secret here.

To my knowledge, this is the first and only picture showing this particular variant of this GPU (GP102-350-K1-A1). Pay attention to the missing memory module.

NVIDIA GTX 1080 Ti PCB vs NVIDIA TITAN X (Pascal) PCB

Now let’s look at the GTX 1080 Ti PCB. Right below we have a comparison between TITAN X and 1080 Ti. The first thing to notice is that both cards use the exact same board (PG611). So the missing DVI port was not dictated by a new design. The removal of that bulky connector simply added more room for the air exhaust, basically to increase the cooling capacity of the new vapor chamber design. Add-in board partners can still use reference PCB and add DVI back if they wish to (and I’m pretty sure most vendors will still add DVI ports).

Compared to TITAN X, the GTX 1080 Ti still features 7-phase power supply, with the exception of dualFET design. To make it simpler, I marked all missing parts with red. So it’s rather straightforward that TITAN X has less advanced power delivery. Meanwhile, GTX 1080 Ti lost DVI connector and one memory module. I guess this was the compromise — to make TITAN X the only 12GB GeForce, but 1080 Ti could easily use the same memory capacity.

NVIDIA GTX 1080 Ti will be released on March 10th. The reviews of the Founders Edition will be available at that time. NVIDIA didn’t really give much time to AIBs to develop their custom designs, so don’t be surprised if they are not available that soon.
