The Intel Core i5-4570 is a relatively fast quad core desktop processor based on the 4th generation Haswell architecture which was launched in Q2 2013. With a base frequency of 3.2 GHz which can boost to a maximum of 3.6 GHz turbo, it has a good effective speed of 93, with a particularly impressive single-core of 98. Unlike the ‘K’ model processors, the i5-4570 is not unlocked, so the max overclocked speed is limited. Whilst this is a great CPU looking at the 4690K versus 4570 shows that the unlocked 4690K offers 20% more performance but at a 20% price premium. The i5-4570 also features integrated Intel HD Graphics 4600 which is about 25% better than the previous HD 4000 Graphics but still not good enough to enjoy modern 3D games. [Nov '14 CPUPro]
