People who are looking for performance don't care about how much electricity is being used. Let's be fair the difference is counted in pennies per month and I know this from experience. I've owned a GTX590;In performance maybe, but in efficiency they would probably be cards to simply avoid.
It's not as big a problem as you'd think.Not to mention the problem that would be to cool a card with so much power consumption!
All I'm saying is that they could have done it, and with Navi they still can. It makes more sense. If I were AMD, I'd pull out all the stops and build an RTX Titan killer. They can do it and likely at a much better price to the end user while still making solid profit.I can see that happening with Navi, but with Vega architecture, I just think it would be a waste of time for AMD.
What I'm waiting to see is AMD's answer to RTX's RTRT. Come on AMD, get on it!
