The meaning is the same but the grammatical structure differs. Await must have an object and usually is an inanimate object. My personal opinion: await is rarely used in normal conversations.

"Await" is basically "to wait for" so it would be used in something like "The long awaited debut" is saying the same as "The long waited for debut" or "I await your return" is "I will wait for your return". In day to day English "await" is fairly rare. "Wait" is used in many cases, such as "I will wait for you", "Wait 5 minutes", etc. Basically almost any time you would use "esperar" you would use the verb "to wait".
