Sorry, but such a camera does not exist. I wish one did. It'd be great to have a point-and-shoot capable of great action shots. To take pictures "really fast", you need a dSLR. To my knowledge, all point-and-shoot systems have shutter lags that make them unusable in action situations (kids, dogs, sports).
The Samsung above is going to be the same as anything else. I looked around quickly online, did not readily see any information to the contrary.
My advice for basic point-and-shoot systems is to look at the Canon Elph or Sony series. Right now, the current model I suggest is the Sony W220:
There are some nice refurbished dSLRS from Pentax out there, for low budgets. And then Nikon D40 kits are on clearance here and there.
