Based on the information leaked in the latest updated of AIDA64, the upcoming GPU appears to be based on the TU102, so it is certainly an enthusiast-grade model. It may end up as either the RTX 2080 Ti Super, the Titan RTX Black or a new Quadro RTX professional GPU.

The RTX T10-8 cards are used in servers for their GeForce NOW cloud gaming platform; presumably multi-session units like the Tesla P40s.
