The i5 5200U. Im typing on my laptop that has that right now actually. The i5 consumes far less power, important for a laptop. 15W vs 35W. Smaller lithography, the i5 will run cooler and more efficient than the AMD. Speeds and capabilities dont mean much when the CPU is thermal throttling itself in games. Out of experience, the HD 5500 GPU of Intels CPU is pretty impressive. I can run Tombraider well on low, world of tanks well on medium, I can actually get 30 FPS steadily in Star Wars Battlefront on low. Really is impressive. AMD has higher clocks, but still weaker cores than Intel. for example, the AMD FX-6300 in my desktop is at 4.5 GHz, but almost any i5 at say 3.1 GHz will beat it by a long shot. Everything to intels architecture to manufacturing tech is better and remains true in this case.
