The i7-8700K is Intel’s latest, top of the range, 8th generation Coffee Lake processor. Like Kaby Lake and Sky Lake before that, Coffee Lake is based on Intel’s 14nm architecture which has been slightly optimized on each iteration. Following AMD’s modus operandi, Intel has upped the cores and threads across the range of their CPUs. In previous generations, a 6-core processor would have been a high-end desk-top (HEDT) processor, however the i7-8700K is the first Intel CPU with 6 cores and 12 threads to be classified (and priced) as a mainstream consumer processor. Specifically, the i7-8700K features a base clock speed of 3.7 GHz which boosts to 4.7 GHz (4.5 GHz for the previous generation i7-7700k), 12MB of smart (L3) cache and 2 channels of DDR4 RAM. The majority of the performance improvements over the 7th generation stem from the higher core count which results in a 50% increase in multi-core speed between the i7-7700k and i7-8700k. A new motherboard will need to be factored into the budget when upgrading to the 8700K as it requires a new Intel Z370 chipset which has supposedly been designed to better deliver power to CPUs with a greater number of cores. Also available in this latest release of CPUs is the 6 core 6 thread i5-8600k which is a more rational option (around $100 cheaper) for the vast majority of users that don’t require hyper-threading. Sandy bridge owners can finally justify an upgrade but with the next iteration of AMD's Zen architecture just around the corner the CPU market will be a lot faster moving now that Intel, once again, has to compete. [Sep '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]
