Both Truncate and delete deletes the rows from a table . 
But we cant use where clause in truncate statement . While 
doing delete operation all the deleted rows are logged in 
the transaction log . It reduces the perfomance . In 
truncate operation no transaction logging is happening . 
Delete is Autocommited but Truncate is Not .

Truncate deletes all rows from table. But Delete deletes 
row/rows by condition.

truncate delete all records from the table and it is auto 
commit. We can't able to rollback the data after performing 
truncate operation.

delete statement delete the specific or all records from 
the table. But we can able to rollback the deleted record

truncate deletes records from a table and while truncating a
table, the table will be dropped from the database and will
again be created automatically. No where clause is
acceptable in truncate statement and one can't restore the
previous data (i.e no rollback is possible) into the table.
It's an efficient process.

Delete statement will delete a particular row(s) on your
choice.
