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 AMD Phenom II X6 1100T was the last, in a long line of Phenom II X6's. The series went 1045T, 1055T, 1065T, 1075T, 1090T and finally 1100T. Each successive release was clocked slightly higher ending with the 1100T which had a base/turbo clock speed of 3.3/3.7 GHz. The X6 has six processing cores and demonstrates very good multi-core performance but it is less able to handle single and dual core workloads, which is what the majority of consumer desktop computing requires. The X6 series were good overclockers with the ability to boost stock clocks by around 20%. Comparing the 1100T to the similarly priced i5-2400 shows that Intel's mid-range Sandy Bridge processor, which was released just a month after the 1100T, was around 8% faster for single and dual core workloads but slower by a staggering 30% for multi-core workloads. [Mar '14 CPUPro]
