The 50-series is made using the same manufacturing process ("node") as the 40-series, and there is not a major difference in design. So the 50-series is more like tweaking an engine that previously topped out at 5000 RPM so it's now topping out at 6000 RPM, without changing anything fundamental. Yes it's making more horsepower but it's using more fuel to do so.
