there is a GTX 1080 "GP-104-100" 60Mhs ETH
I'll believe that claim if I see it. There is no way they could DOUBLE the performance of a GTX 1080 on ETH while leaving it on GDDR 5x (excessive latency issues), and even if they moved it to GDDR 5 (not X) I doubt they could get it to 50 even with super-upgraded memory timings.
On the other hand, I've seen 30% power savings quoted for the GP104-100 - THAT seems possible, especially if they "factory undervolt" it at all compared to existing GTX 1080 cards.
That "60MHs" threw me off too and asked my contacts to provide some proof...
and he sent me this:
apparently NVIDIA has gone all out to get a killer mining card out with custom PCB, passive-cooling and custom ROMs.
http://wccftech.com/nvidia-pascal-gpu-cryptocurrency-mining-price-specs-performance-detailed/ Not a new article, and still does nothing to explain how the mining-specific card could achieve that much higher performance than non-mining GTX 1080 cards can manage.
On the positive side, though, EVGA involvement indicates a high probability of SOME of these cards being available to small miners.
On the other hand, Nvidia might actually be starting to feel some pressure - 1070 pricing IS climbing quite a bit, currently back near or into low-end 1080 pricing and availability getting spotty.
wcctech has a spotty record on "upcomming scoops" - sometimes they get it right, sometimes they blow it entirely (like the RX 490 they were talking about a couple months or so back that never happened).
There have been a few different sources on the GP106-100 though inplying that SOMETHING is going on there - the GP104-100 still seems to be going back to one or 2 root rumor sources, but it would be nice if it DID happen.
