Samsung to release Galaxy S5

One will run the quad-core Snapdragon 801 with a 2.5GHz clock speed along with another model powered by an octo-core Exynos SoC running at 2.1GHz.  There was a Galaxy S4 flavor that ran a previous version of the Exynos Octa-core. That model was designed for and exclusively sold in the Korean market.

The additional cores do not make a notable difference in real world situations, as reviewers found little difference between the Galaxy S4 variants.
