The chip has 48GB of RAM onboard, so there is a ton of stuff to play with.

The PG137 board design is a potential TITAN RTX ADA board, and it appears to come in two different SKUs: SKU 0 and SKU 330.

A picture of the TITAN RTX ADA GPU was recently leaked (above), which had a quad-slot GPU design with a vertical PCB with stacked display connectors. The PCB itself would be parallel to the motherboard. This could mean that the design of motherboards might be about to change.

The design is clearly in the advanced development stage and even has the same colour as previous generation TITAN models.
