Simplify the following text for a Grade 12 native English-speaking person.
Original: A superscalar CPU architecture implements a form of parallel computing called Instruction-level parallelism inside a single processor which allows faster CPU throughput at the same clock rate .
Simplified: A superscalar CPU architecture implements a form of parallelism called instruction level parallelism within a single processor . It therefore allows faster CPU throughput than would otherwise be possible at a given clock rate .
