The Kepler structure is scalable. You want your dev platform to be the same architecture, but scaled up to speed up development (Dev platforms are not for testing, you test on the actual devices). This would require more power and a higher thermal envelope, obviously. You think this is unique? It's the same way developers for ios apps develop on macbook pros, instead of on iphones.The demos, running here, are running on actual tegra k1 prototype tablets. To say that running Trine2 smoothly is not impressive...is strange. It IS impressive for a mobile device to have graphics capabilities at that level. Otherwise, what would be the point of showcasing such?
