No, not at all, though they are similar and look the same.
If you are Taping drywall (sheetrock) fill the nail or screw rows with All Purpose Joint Compound- (1st time)
Then use Topping Compound 2 more times to each row of nails or screws-
Whats the difference between AP Joint Compound and Topping Compound A BIG DIFFERENCE!
So with AP (all purpose) it is designed for embedding the tape to the drywall joints it has more acrylic glue then in it then Topping Compound for example if you used Topping compound to try and tape drywall joints it will fail and actually start to come loose from the the wall or ceiling!
It is called topping compound because it goes on *Top of the joint compound and it is very smooth and very easy to sand-
Where as Joint compound is very gritty and hard to sand (very)
the word *All Purpose is used because it can be used to embed drywall tape and you can Topp with it (NOT RECOMMENDED!) and you can use All Purpose Joint Compound to Texture with (*RECOMMENDED)

They're not the same thing, spackle is used to fill in holes or indetations made from nails in drywall while joint compounds are used to join drywall panels together.
