The Intel i5-4440 is one of the cheaper four core Haswell processors. Unfortunately it is clocked at just 3.3 GHz Turbo, which is 15% lower than the leading Haswell i5 and because it has a locked multiplier there is little that can be done about it. Comparing the 4440 to the 4670K shows that the 15% reduction in Turbo clock speed basically results in a 23% performance loss to the 4670K. The Pentium G3420 actually has a higher base clock speed and costs about a third as much as the i5-4440 yet for the majority of, single and dual-core, desktop orientated tasks offers comparable performance. I don't think the i5-4440 makes much sense and would prefer either a much stronger 4770 or the weaker but much better value G3420[Mar '14 CPUPro]
