Which GPU is that? It was only a few days ago you were saying the Scorpio would perform akin to a 9 - 10tf PC, but i'm not aware of any 20tf GPU's :p

I know you are being sarcastic.
But you can have a 20 Teraflop PC configuration.
* You just need four Radeon 290X's in Crossfire which is 22.4 Teraflops.
* Two Radeon Pro Duo's in Crossfire would give you 32.6 Teraflops.
* Three Fury X GPU's would give you 25.8 Teraflops.
* You can also do 20 Teraflops with four Radeon 480's.
Any Radeon 480, 390, 390X, Fury, Nano, Fury X, Radeon Pro Duo, 295 X2, 290, 290X, 7990, 6990 in a Dual-GPU configuration can hit 10 Teraflops or more.
Vega is likely to do anywhere from 6-10 Teraflops for a single GPU...
But this undermines the entire issue at hand. Despite many of these configurations having roughly the same theoretical "flop" number, in the real world they do and can perform vastly differently for various reasons and thus flops is not an accurate denominator for gauging the complete capabilities of a graphics processing unit.

I know there are configurations that can hit the overall mark, as it happens i was building this ( http://imgur.com/DXvvKv7 ) today, which would hit around 16.5tf (or at least the base versions would, these's ones are slightly clocked up).
His wording though (coupled with other replies, and his discussion with CGI in the thread i was referencing) implies he was referring to a single GPU. Both here and in that other thread though he was actually referring to performance (which makes everything much more complicated, both because of the reason you noted, and because SLI isn't 100% efficient), so i was replying relative to his previous estimate for what the Scorpio would be capable of, versus whatever PC he was imagining in the world where flops made for perfectly linear comparisons.
