The Intel Core i7-5820K is the cheapest of three (5820K,5930K,5960X) new Haswell-E prosumer/enthusiast processors. The 5820K sports six physical cores and twelve threads which allow for enormous processing throughput. Unfortunately Intel have somewhat handicapped the 5820K by setting its base clock at just 3.3 GHz, 0.7GHz lower than the class leading 4790K. Comparing the 4790K and 5820K shows that the cheaper i7-4790K is significantly faster at both single and dual threaded workloads. The additional two cores found in the 5820K are not relevant to general computing and as such the 5820K probably makes a better server rather than consumer proposition. The Haswell-E X99 architecture also requires DDR4 RAM which is currently far more expensive than DDR3. Overall the 5820K is a very expensive option and probably best avoided by the vast majority of consumers.  [Sep '14 CPUPro]

Intel’s latest 10-core i5-12600K Alder Lake desktop processor offers an impressive 50% 64-core performance improvement over it's predecessor. The 12600K combines six hyper-threaded Golden Cove P-cores with clock speeds up to 4.9 GHz and four energy efficient Gracemont E-cores for a total of 16 threads. Alder Lake CPUs have a new LGA 1700 socket which requires new cooler brackets and a new Z690 motherboard. Z690 brings several new features including PCIe 5.0 and DDR5 memory. Most Z690 boards will ship in both DDR4 and DDR5 variants. DDR4 is likely the better option, at least until DDR5 prices settle. With an MRSP of just $290 USD, the 12600K is both cheaper and faster than the competition in both single and, notably, multi-core performance. As a result, even AMD's prolific marketing infrastructure (youtube, reddit, forums etc.) will struggle to drive sales, at least until Zen 4 launches (est. late 2022). In the meantime, Intel's i5-12600K is the obvious choice for consumers that do not wish to pay over the odds for almost unparalleled performance in the majority of workloads including gaming. That said, gamers that already own a K series CPU from the 8th gen. or higher will see limited gains in the majority of titles when paired with a 3060 (or lower) tier GPU. In some cases (e.g. PUBG or Overwatch) gamers will see fewer frame drops by disabling the E-Cores all together. If recent history is a guide, stock levels at MSRP are likely to deplete rapidly. [Nov '21 CPUPro]
