The AMD FX-8150 is the earliest eight core variant in AMD's flagship FX series. The FX-8150 was released in October 2011 and at that time it superseded the Phenom 1100T. Comparing the 1100T and FX-8150 shows that the newer FX-8150 has roughly the same single and dual core speed but, thanks to its extra two cores, pulled ahead of its predecessor by 15% in multi-core tests. The performance improvements over the 1100T are accompanied by an improved manufacturing process which reduced lithography from 45 to 32 nanometres; consequently both processors have the same maximum TDP of 125 Watts. Thanks to its eight cores the FX-8150 has strong multi-core performance but its single-core core speeds are still relatively weak compared to similarly priced Intel chips. [Mar '14 CPUPro]

The Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]
