The Core i7-6950X is Intel’s new top of the range prosumer CPU. This flagship model has a whopping ten cores with base and turbo frequencies of 3.0 and 4.0 GHz respectively. The 6950X is based on the 14 nm Broadwell-E architecture. It has a TDP of 140 watts, 40 PCIe 3.0 lanes and no integrated graphics. Because of its ridiculously high MSRP of around $2,000, this CPU only makes sense for very niche use cases which could include top end graphics design or video production workstations. Comparing the 6950X and 6700K shows that for typical desktop use the 6950X only offers a gain of around 20% for a whopping 6 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 6950X. That said, if you want the most powerful desktop processor money can buy, then the 6950X hits the spot. [Jun '16 CPUPro]

The Intel Core i5-4690K is the latest incremental upgrade to Intel's unlocked mid-range quad core family of processors. The 4690K replaces the 4670K. Comparing the 4690K and 4670K shows that little has changed. The two chips share identical architecture; in fact the only difference between them is a 100 MHz bump to both the base and turbo clocks. The 100 MHz bump translates to an insignificant 2.9% performance increase. In terms of outright performance the 4690K has an effective speed of 103 which thanks to its superb single and dual core performance, is 12% stronger than the average of the group leaders. Overall the 4690K brings nothing new to the table so owners of previous flagship i5's will gain little by upgrading but as a new purchase the 4690K is a strong contender for both power users and high end gamers. [Jul '14 CPUPro]
