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]

The Intel Core i3-4350 is a refreshed version of the Haswell i3-4330. The newer i3-4350 has received a 100 MHz increase in clock speed which translates to a performance improvement of 2.8%. With an effective speed of 93.5 the i3-4350 is no slouch and offers performance that's slightly above the average of the ten group leaders. Similar to the G3258, the 4350 has a performance profile which favours single and dual core workloads. Comparing the G3258 and 4350 shows that not only does the G3258 offer far better overclocked performance but it also costs less than half as much as the i3-4350. Although the i3-4350 is not a bad processor, there are relatively few use cases that would justify its price when compared to the stellar G3258. [Jul '14 CPUPro]
