Depends on the cpu i'm pretty sure. I'm assuming the dual core i5 2410M in my laptop with hd3000 graphics is less powerful than a desktop model, but my laptop can run all the valve games (tf2 L4d2 Portal2) pretty well at 1366X768. It can't run gta4 at all, however. It also should depend on your ram since it is shared as graphics memory. I have 6Gb in my laptop. I don't own any of the other games, but I'd say my laptop wouldn't be able to run Deus EX or Dirt 3.
