Any current generation laptop with an integrated graphics core should be fine for playing The Sims 3 in general.
Exactly which laptop depends on your budget. AMD's A10 APU has more a powerful graphic core vs Intel's Haswell generation Core i3/i5/i7 CPUs. However, from a raw processing performance point of view Intel CPUs easily trumps AMD's APU. But for games it is usually the graphics core that is more important.
In terms of budget... generally speaking anything new selling for less than $600 will have integrated graphics. This excludes any new laptop that is on sale with a large discount. Laptop with dedicated graphics chips tends to start at $700; again excluding any sales.
