This is yet another processor from Intel that demonstrates their total market domination in the high end PC sector. The 4820K isn't really a step forward in any particular direction but rather a variant on what's already been available (performance wise) for a few years. As long as Intel is largely competing with itself they will likely continue with these sorts of incremental releases. The 4820K requires an Intel X79 chipset, which dates back to Sandy Bridge-E and lacks some of the newer features like native USB 3.0 support. An investment in the 4820K only makes sense if you already own an LGA2011 Motherboard and could be seen as good money chasing bad given that the platform is due an upgrade. That said the 4820K is a very capable multi-core processor and it sits amongst the top handful of processors in this regard. For typical consumers a Haswell i3 will offer mostly identical response times, a lower energy footprint and a significantly more competitive price. [Nov '13 CPUPro]

The Intel Core i3-4160 is a dual-core four threaded 4th generation (Haswell) processor. It was released in Q3 2014 and scores a respectable 91 for effective speed. With its base frequency of 3.6 GHz, the 4160 is fast enough to run the vast majority of applications smoothly and it’s very reasonably priced for its performance which make it a sensible choice even when considering building a gaming PC. Although the integrated Intel HD Graphics 4400 are absolutely fine for general desktop use such as web browsing and word processing they may bottleneck a gaming machine. A 20% price premium would buy the slightly older i3-4350 which has a 33% larger (4MB) cache but its only about 1% faster (full comparison here). Overall the i3-4160 represents the best value for money I have seen outside Intel's Pentium and Celeron range of CPUs. [Nov '14 CPUPro]
