Re: next gen kepler to support dx 11.1, also take a year to rollout all cards
We don't know the performance or actual power draw yet so it's a bit soon to say that they are inefficient. Fermi was inefficient on perf/trans and perf/watt compared to Cypress/NI for gaming yes, but much of the design was designed for GPGPU. Now that both are strong in this area a real comparison can be made. There's also the common occurrence of that last 10-5% performance costing much more in transistors and power use - if the top end Kepler does use up to 300w, but performs 20-40% faster than Tahiti, I don't think that's really THAT unreasonable. If it's just 5-15% again, that's not worth it for me.
