In brief: Probably Not Much
To my knowledge, these are expressions for the same condition.
Aspergers is now part of what is called the autistic spectrum, a range of conditions sharing characteristic of autism, but with different levels of severity.

In brief: Subtle Differences
Clinicians usually use the term hfa (high functioning autism) when some of the diagnostic features of aspergers are missing.
For example, children with asperger's should not have any significant delay in language development. If a child with features of asperger's had a history of language delay, they may be deemed to have high functioning autism instead of aspergers'.

In brief: Subtle differences
The term high functioning autism is not well defined.
If one were to compare a person with autism, who is high functioning and a person with asperger's disorder: persons with asperger's d/o have a desire to be socially normal, but don't know how to be. Persons with autism, even when higher functioning, typically don't have the same desire for social interaction.

In brief: Not much
"autistic disorder"will include as, pdd-nos & autism.
Kids with as may sound like " little professors, "talk about favorite topics without conversational give-and-take( pragmatics) and without typical use of tempo, pitch & loudness (prosody). Kids with hfa struggle with language, but may quickly figure out how to make something work by seeing & handling it. Both have "normal" full-scale iq, >70.
