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]

At a list price of just $129, the quad core, Ryzen 3 1300X is a great budget CPU. The Ryzen 3 series is based on AMD's powerful and energy efficient Zen core architecture as already featured in the mainstream Ryzen 5 series and performance Ryzen 7 series, both launched earlier this year. The 1300X is fully unlocked with a stock base clock speed of 3.5 GHz running up to 3.7 GHz for boost and has a TDP of 65W. The 1300X comes with AMD's Wraith Stealth cooler, but significantly, it is devoid of integrated graphics. Although this can be inexpensively rectified, it may be a stumbling block to those at the entry-level of the market. By comparison, Intel's dual core, four thread i3-7350K comes with 630 HD integrated graphics. In terms of effective speed, early benchmarks for the 1300X just pip the 7350K to the post but results in specific games will depend on the extent to which the game is able to use more than two processing cores simultaneously. The 1300X scores around 20% higher on quad-core tests whereas the 7350K scores 16% higher on single-core tests. The Ryzen 1300X has been released alongside the similar Ryzen 3 1200 which is also an unlocked quad-core with slightly lower base / boost clock speeds of 3.1 / 3.4 GHz and a slightly lower price of just $109. [Jul '17 CPUPro]
