Thoroughbreds are generally the fastest, as they are the most popular breed of racehorse. Quarter Horses can run the fastest for a quarter of a mile, hence their name, but arâ¦e not the fastest overall. In other parts of the world, Arabians are also commonly used for racing.
The latest is the FX series. Check out the following links for more info. All cpu's are 8-core. I think the most recently released would be the A10-7870K, but that isn't the highest performing AMD CPU, that would be the FX-9590, which comes with a stock water cooler.
At the other end of the spectrum is the Sempron 3850, one of AMD's cheapest quad-core processors. It sports a Kabini core and is built on a 28nm process, which explains why its TDP only reaches 25W, almost one seventh of the FX-9590. Obviously, the fact that it runs at only 1.3GHz also helps a lot.
