The Core i7-4960X is Intel's top of the range desktop processor which sports six physical and twelve hyper-threaded cores. The 4960X was released in 2013 but it uses an FCLGA2011 socket which is supported only by the X79 chipset and is now three years old. As a result an investment in this processor forgoes the last three years worth of platform advances which include, amongst other things, on-board USB 3.0 and additional SATA 600 MB/s ports. Comparing the 4960X and the 4930K shows that when overclocked, the 4930K is able to best the extreme 4960X at nearly half the price! Finally comparing the latest Haswell 4770K to the 4960X shows that 4770K is again able to best the 4960X, this time at a small fraction of the price. The 4960X is significantly overpriced and there is far better value available elsewhere. [Mar '14 CPUPro]

The Intel i9-9900K is an 8 core, 16 thread, unlocked 9th generation Coffee Lake processor. It has a base / boost clocks of 3.6 / 4.7 GHz and a single-core boost of 5.0 GHz (the highest frequency achieved yet from this class of Intel CPU). It features 16 MB of cache, a 95W TDP and Intel UHD 630 graphics. The 9900K is compatible with the new Z390 chipset, and subject to a BIOS update, is also compatible with the older Z370 chipset. Aimed at users who do not wish to compromise, the i9-9900K offers the best gaming and desktop experience available at any price. Heavy workstation users should consider the Ryzen 9 3900X which is similarly priced. Comparing the overclocked 3900X shows that it is just 10% worse for gaming and desktop (sub octa-core) but around 40% better for 64-core computations. Gamers should consider the 9700K which offers identical overclocked gaming performance at a $100 USD discount. [Oct '18 CPUPro]
