well ... it was wishful or hopeful thinking :-) I do hope to see better performance but I'm not as optimistic now as I was at first (got some pretty enlightening comments on the post)
This is one thing that impressed me with the 3080 .. it looks like 2 of these will be around the performance (for some compute tasks) of 4 x 2080Ti The 4 2080Ti would max out at 1KW the 2 x 3080's at ~700W ...
