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]

The budget Ryzen 5 2400G is a four core, eight thread APU (accelerated processing unit: combined CPU and GPU) from AMD’s Raven Ridge product line. It has a base clock of 3.6 GHz which boosts to 3.9 GHz. Its RX Vega 11 graphics scores an average bench of 20% which is at the forefront of performance from integrated graphics and is 34% faster than the RX Vega 8 graphics found in the Ryzen 3 2200G (the 2400G’s ultra budget sister APU). The 2400G currently retails at $162 and includes a Wraith Stealth cooler. This puts it in direct competition with Intel’s quad core Coffee Lake i3-8350K at $167, which does have a 26% faster effective speed. However, the 2400G’s integrated graphics are far stronger (137%) than the 8350K’s, making the 2400G a great choice for those looking for an economical multimedia PC or a super budget gaming PC. [Apr '18 CPUPro]
