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]

AMD’s 16 core, 32 thread Ryzen Threadripper 1950X is finally here to seize the throne for high end desktop processors. The 1950X is the flagship of the Zen based Threadripper series which also includes the 12 core 1920X and the 8 core 1900X. The 1950X has a stock clock of 3.4 GHz increasing to a maximum single core boost of 4.0 GHz and features quad channel DDR4 and 64 PCI Express lanes. This processor is effectively two Ryzen 7 1800Xs glued together with Infinity Fabric (AMD’s scalable interconnecting technology), making the 1950X one of the physically largest CPUs on the consumer market. If you are considering this CPU, you will need a new X399 motherboard with a TR4 socket. Early benchmarks show the 1950X competing with Intel’s similarly priced i9-7900X. Whilst the 7900X has slightly higher single and quad core scores (10%-15%), the 1950X is around 35% faster for multi-core workloads. Content creators, and other core intensive task masters will not be disappointed. [Aug '17 CPUPro]
