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 i3-4150 is successor to the i3-4130 2013 Haswell processor. Looking at the 4150 and 4130 side-by-side shows that the only difference between the two processors is a 100 MHz base clock increase from 3.4 GHz on the older 4130 to 3.5 GHz on the newer 4150. The marginal 2.9% clock speed increase brings an equally marginal performance boost. Despite the academic performance gain over it's predecessor, thanks to its excellent single-core performance, the i3-4150 is still an extremely capable desktop CPU and will handle the vast majority of regular desktop computing without breaking a sweat. Coupling the i3-4150 with a discrete GPU will satisfy all but the toughest of gaming requirements. Only the lower powered but significantly cheaper Pentium G's offer better value for money. [Jun '14 CPUPro]
