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.
Bottom Line: Within the AMD line, what makes for the fastest processor depends on whether you care most about on-chip graphics or raw computational processing power. If the former, investigate the Kaveri FM2+ APUs; if the latter, the AMD FX series is as good as AMD silicon gets on the consumer side of things.
