Going to kill perhaps. Those are not on the shelves yet and availability might be a factor. I've seen Nv 750 launched at 180
EUR at some e-shops around here.
For pure compute I don't think they make GCN1.2 obsolete, main problem Tonga has always been overpriced, especially in its 2GiB variant (bleh)!
To me it looks more like a die-shrunk 285/380
Nope. Node shrink + new architecture iteration. It is known they have new instructions.
The 1070 however does about 27MH/s at the same bus type and speed, at 125W
A 70% price increase for 16% lower consumption? They will have do take down the upfront cost considerably. How expensive are 1070s for you?
