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 8 core, 16 thread 2700X is AMD’s second generation Ryzen 7 flagship following in the wake of the Ryzen 7 1800X which continues to offer excellent multi-core value for money. This new Pinnacle Ridge processor features the Zen+ architecture with 12nm lithography compared to 14nm previously. Whilst there is no increase in the number of cores, the stock base / boost clocks appear to have received a bump up to 3.7 / 4.3 GHz from 3.6 / 4.0 GHz. The 2700X is compatible with both the new 400 series and 300 series of motherboards. Early benchmarks indicate that the 2700X has a slightly greater effective speed than the 1800X, although further benchmarks are necessary to quantify this. The expected launch price of $329 includes a Wraith Prism cooler and is in the same price bracket as the 1800X and Intel’s Coffee Lake i7-8700K. Whilst the 6 core, 12 thread 8700K beats the 2700X in single and quad core performance by about 10%, the 2700X wins on multi-core workloads. PC gaming and desktop performance is generally governed by six or less cores but the 2700X offers value for money to workstation users. Even though the 2700X excels at pure multimedia production streamers should look elsewhere. Streaming with dedicated hardware such as NVENC or a separate stream PC will nearly always result in fewer dropped frames. [Apr '18 CPUPro]
