Specifications of Nvidia's RTX 2080 Ti have been leaked on PNY and removed shortly thereafter but a quick Reddit user named SassyBlackyJackyChan managed to snag screenshots of both the specs and the price which stood at $1000 flat.
While RTX 2080 Ti does look more powerful than a GTX 1080 Ti, one might argue it is not necessary yet. At least not until the next generation of consoles comes along with higher requirement for 4K HDR with 120 FPS gaming. Consoles, 120FPS, get it?
That said, the specifications leaked by PNY and relayed by SassyBlackyJackyChan provide more insight into the GPU that's actually more powerful than 1080 Ti, unlike RTX 2080. RTX 2080 Ti will feature a staggering 4352 CUDA cores, surpassing the 4096 of Radeon RX Vega 64, which even the GTX 1080 Ti didn't manage, having "only" 2944.
One somewhat similar feature between RTX 2080 Ti and GTX 1080 Ti is that both cards feature 11GB of RAM, except that the RTX 2080 Ti will have GDDR6 instead of GDDR5X. The memory interface will be the same as it was in GTX 1080 Ti, with width of 352-bit.
Power consumption will be slightly higher for RTX 2080 Ti, standing at 285W and power input will go through two times 8-pin plugs. That alone states the GPU should be rather large in size so if you though about putting it in your rig, you may want to assess available space first.
The RTX 2080 Ti will have significantly higher memory bandwidth with 616 GB/s as opposed to 484 GB/s of GTX 1080 Ti. It will, however, have a slightly lower boost speed with 1545 MHz versus 1582 MHz of GTX 1080 Ti.

Based on these specifications, RTX 2080 Ti looks like a bit of an upgrade from GTX 1080 Ti, but it will not necessarily find its way to many must-have lists. For example, one of the most anticipated hardware hogs, Cyberpunk 2077, already ran in 4K at 30 FPS on GTX 1080 Ti, on a build with no optimisation. Therefore, your GTX 1080 Ti should do just fine in foreseeable future.
