For someone interested in buying a cpu these days.Core i5 3570K and Core i5-4670K For those who know me and have me do their builds, you’ll know that those really are currently just about the best processors you can get for the money today. With plenty of performance, top notch overclocking capability and enough horsepower to run any game you throw at it, the choice is a no brainer.You would not need to upgrade either of those for many years to come bud.As far as which is better i honestly could not say for sure so wait for more replies with valid trustworthy respected links for you.But basically The Core i5-4670K, based off the Haswell architecture, replaces the last generation Ivy Bridge based Core i5-3570K, which was among the top processors for gaming from both a value and performance standpoint. With the Core i5-4670K, this story hasn’t changed.
Despite Intel focusing on power efficiency with the new Haswell processors, the new Core i5-4670K is once again a performer, sporting the same 3.4 GHz clock speed with the ability to turbo up to 3.8GHz as the last generation Core i5-3570K. That said, despite the Core i5-4670K receiving identical clock speeds as its last generation counterpart, it’s still able to pull of up to a 10-20% performance improvement depending on the workload.
In addition, as long as you make sure to get ’ K series processor, which has a factory unlocked multiplier to allow for easy overclocking as well. Since Haswell’s overclocking ability is relatively similar to what we saw in last generation Ivy Bridge parts, a mild overclock of up to 4.0-4.6 GHz (~15-25%+ performance improvement) is easily achievable with proper cooling.Annyway,hope this helps good luck!
