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]

The FX-8320E is a Vishera eight core processor based on AMD’s Piledriver architecture. The ‘E’ in the FX-8320E denotes energy efficiency with the FX-8320E boasting a TDP of 95 Watts which is relatively low for FX processors. The FX-8320E was launched in September 2014 at the same time as the FX-8370E. Comparing the 8370E and 8320E shows that the performance profiles are similar with the 25% more expensive 8370E edging ahead, particularly on single core workloads. The 8370E is clocked slightly higher with base/turbo frequencies of 3.3/4.3 GHz versus the 8320E’s 3.2/4.0 GHz. Overall the 8320E scores a mediocre effective speed of 70. Whilst this is sufficient for the majority of desktop applications: web-surfing, word-processing and playing movies, better single-core performance is offered by any number of Intel processors. [Dec '14 CPUPro]
