The Core i7-6900K is one of four new Broadwell-E prosumer CPUs. This model has eight cores with base and turbo frequencies of 3.2 and 4.0 GHz respectively. The 6900K is based on a 14 nm architecture, it has a TDP of 140 watts, 40 PCIe 3.0 lanes and no integrated graphics. Because of its MSRP of $1,100, the 6900K only makes sense for very niche use cases which include top end graphics design and video production. Comparing the 6900K and 6700K shows that for typical desktop use the 6900K only offers a gain of around 12% for a whopping three fold price increase. This is because desktop computing largely depends on single core performance and the Skylake i7-6700K is both clocked higher and has higher IPC due to its one generation lead over the 6900K. That said, as a workstation CPU the 6900K is bested only by the $2,000 flagship ten core 6950X. (6900K vs 6950X[Jun '16 CPUPro]

The Core i5-4690 is Intel's latest and greatest locked Core-i5. This CPU will suit serious gamers that don't plan on overclocking. The 4690 replaces the 4670 and shares exactly the same specs aside from base and turbo clock bumps of 100 MHz. The 100 MHz clock bump results in barely noticeable real world performance improvements and, if anything, makes the older 4670 more attractive as suppliers reduce prices to try to clear stocks. For regular desktop use such as email, surfing, and listening to music, this CPU is overkill and there is far better value amongst lower powered and significantly cheaper CPUs but for gamers and moderate power users the 4690 is a good locked option. [Jun '14 CPUPro]
