This is interesting:

I know it is Nvidia news and WCCFTech, however 14TFlops doesn't seem like much of a leap over the Vega's (Frontier) 13TFlops. Particularly so when Vega has had it's front end completely re-designed to remove the famed Fury X bottlenecks.
One thing to note, the article mentions V100 as having 5376 Cuda cores, which gives peak TFlops @ 1550MHz as 16.6TFlops, which is quite a bit above Vega. Remains to be seen what clocks they can achieve on a 21B transistor chip though
Obviously memory bandwidth may be Vega's biggest issue... Oh well, only 7? days to benches!
