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]

Within minutes of this unrealistic, pre-release, result appearing on userbenchmark, AMD’s marketing machinery declared a 20% victory over the 12900K whilst simultaneously slandering userbenchmark via hundreds of “news” outlets and thousands of supposedly disinterested twitter, reddit, forum and youtube accounts. Buying new AMD products is like buying used cars: it takes time, experience and a taste for sales hype. It’s difficult for consumers to make rational choices because AMD completely dominates “news” and social media channels. Ten years ago, when AMD was the underdog, this type of marketing was understandable. Today, with a capitalization of $150 Billion USD, it’s disrespectful to AMD's own users. Even with Intel's marketing department permanently asleep at the wheel, If these practices continue, Ryzen may eventually end up in the same state as Radeon. Following a series of overhyped releases, consumers have little interest in the Radeon brand. The combined market share for all AMD’s (discrete) Radeon RX 5000 and 6000 GPUs (Jun ’22 Steam stats) is just 2%. Meanwhile, Nvidia’s RTX 2060 alone accounts for 5%. If Zen 4 actually delivers anywhere near a 57% real-world single core uplift, we will bow down, call AMD king, and commit seppuku! AMD’s new architecture is, once again, optimized to shine in specific benchmarks. Realistically, even if Zen 4 only catches Intel's 12th gen. (Alder Lake) in a handful of real-world scenarios, it will be a big step forward for AMD. A few weeks after Zen 4 (est. Sep 27), Intel’s 13th gen. (Raptor Lake) is scheduled to launch. Smart shoppers will do well to wait until then, before considering a purchase. Despite AMD’s Neanderthal marketing techniques, it’s hard not to admire the speed of their technical progress. AMD-Raptor-4 and Intel-Zen-13 would be better fitting product names. [Jul '22 CPUPro]
