The Intel i5-4200U is a dual core 4th generation Haswell processor. Specifically designed for tablets and ultrabooks it gives the appropriate balance between performance and battery life. The i5-4200U has integrated HD 4400 graphics which are fine for desktop use but not suited to 3D gaming. With an impressive TDP of just 15 Watts, the 4200U will typically give 6 hours of battery life. Despite the low effective speed of 56 which is 70% below the average of the leaders, when coupled with an SSD the 4200U can give a reasonable user experience. Comparing the 4200U and 4500U shows that the 4500U has 20% faster single-core performance but also costs 40% more. [Nov '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]
