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 Ryzen 5 3600 is a 6-core, 12-threaded processor that is priced at $190 USD and succeeds the Ryzen 5 2600 improving upon it by 13% in terms of overclocked performance. The 3600 is in competition with Intel’s 6-core i5-9600K. AMD continues to push the multi-core performance envelope: benchmarks show that the 3600 has a 27% overclocked 64-core lead over the 9600K but that the i5-9600K leads by 14% on single to hex core workloads which translates to 10% higher EFps in most of the today’s top games (e.g. PUBG, GTAV and CSGO). Additionally, the 3600's memory controller, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency which adversely impacts gaming. Weaknesses in memory architecture are not readily picked up by CPU benchmarks but they are apparent whilst gaming. Cheaper CPUs such as the 9400F deliver better gaming performance in nearly all of today’s popular games. At $190 USD, the 3600 offers good value for purely workstation tasks such as film production but streamers should look elsewhere. Streaming with dedicated hardware such as NVENC or a separate stream PC will nearly always result in fewer dropped frames. The masterfully hyped Ryzen 3600 may well be the best CPU for multimedia producers on a tight budget but in today's market there are faster and less expensive alternatives for gamers, streamers and general desktop users. [Jun '19 CPUPro]
