we'll have to wait to see that in action. If it has the very same maiorcrch. as GK104 just with more SMX it might easily dethrone Tahiti from GPGPU pedestal, however it's still a step back in field of efficiency. No hot clock, much more ALUs per scheduler that is exactly what AMD dumped (because it's easy to design and implement, can work great with games but doesn't with generic compute, also is highly dependent of compiler performance)
