Superscalar means executing multiple instructions at the same time while chip-level multithreading -LRB- CMT -RRB- executes instructions from multiple threads within one processor chip at the same time .

Chip-level multithreading -LRB- CMT -RRB- technique : using Thread level parallelism -LRB- TLP -RRB- in order to executes instructions from multiple threads within one processor chip at the same time .
