A First Look At The Reference GTX 1080 Ti PCB

Below you’ll see a picture of the Reference NVIDIA GeForce GTX 1080 Ti PCB, which is being directly compared to the Titan X Pascal. The GTX 1080 Ti is based off the same PCB as the Titan X Pascal as they both make use of the GP102 silicon, but there are obvious differences and NVIDIA has made some improvements.

The GTX 1080 Ti has one less memory chip (11 vs 12) compared to the Titan X Pascal. This is because it has a narrower 352-bit GDDR5X memory interface. It does however make up for this narrower bus by having faster 11 Gbps (compared to 10 Gbps on Titan X) memory chips.

The biggest difference between the two card is that the GTX 1080 Ti has a new a 2x dual-FET VRM design. NVIDIA has placed additional MOSFETs and capacitors along the blank traces of the reference PCB. This effectively lowers the load on each individual MOSFET, which in turn lower temperatures. This also allows for higher power limits. NVIDIA has also updated the reference cooling solution with a new vapor-chamber base-plate.

NVIDIA will be releasing the GTX 1080 Ti later this month for $699.
