The 2080 Ti was about 15% faster than the 2080, though, with extra memory. The gap between the 3080 and the 3080 Ti is smaller. Also, Nvidia introduced the 3080 12 GB, which is closer in performance to the 3080 Ti than to the 3080 and has the same amount of VRAM as the Ti.
Also, the 3080 Ti is no longer even the top tier product with all the bragging rights, devaluing it even more.
Apparently, Nvidia will now set a $799 MSRP for the 3080 12 GB, so even at $999, the 3080 Ti would be very poor value compared to one tier lower, let alone at the apparent new MSRP of $1100 or the old MSRP of $1200.
The 3080 Ti MSRP was simply inflated due to no longer being the top tier product and not giving as much performance benefit to one tier down as its predecessor.
