The difference in performance between AMD cards and Nvidia cards in FCPX seems to have definitely closed over the last year or so. Perhaps it's simply brute force but based on Bruce X the difference seems to have significantly closed and the Nvidia Web drivers seems to have increased performance. I used to get mid 50 seconds for my 970 but since sometime in El Cap those numbers have dropped to the low 20s.
The link you provided is over two years old. I'd imagine there are more recent comparisons between Red and Green on the site which might be more illuminating.
The SLI bridge is included in the box for Nvidia cards so that doesn't really seem like a detractor.
FCPX also isn't the only NLE for OS X.
My red devil RX 480 does it in about 12-13 seconds.
Colorfinale plugin not currently working though. Hopefully an update from them will fix it.
