It depends on what you mean by choppy.
Looking at the specs you posted in the hardware section your biggest problem is probably that your ultra-book doesn't have a dedicated graphics card.
But in saying that, what are you settings and what is your FPS? (You can see that by hitting F3 in game)
I wouldn't Call that choppy but if you think that's choppy then try running Minecraft on Fast Graphics if not already, That will really make a diffrence
