Not necessarily. Parallelization has allowed better performance from chips. Adding more cores has allowed better throughput but the benefits are seen more on the application side. They could make the chips bugger, but the problem with expanding outward is the routes connecting the transistors become too long and suffer increased time delay due the increased resistance of the long line. Without being able to make chips larger the only way to get better physical performance is to increase density.
