The 8th Gen “Coffee Lake” Intel Core Processors

Starting at the top, the new Core processor family is led by the Intel Core i7-8700K featuring 6 cores and 12 threads. It features a base frequency of 3.7GHz with an Intel Turbo Boost 2.0 maximum single core turbo frequency of 4.7GHz. Just like all “K” processors, the 8700K is unlocked and can be overclocked. It also has 95W of TDP, 12MB of smart cache and supports dual channel DDR4-2666 memory as well as Intel’s Optane. It comes with an MSRP of $359 USD. There’s also a non-K version, which is the Core i7-8700; featuring a slightly slower clock speed of 3.7GHz to 4.6GHz. It also has 6core/12threads but comes with a lower TDP of 65W and it’s also cheaper compared to the i7-8700K, at $303.

Next are the Core i5-8600K and Core i5-8400, featuring 6 cores and 6 threads, 9MB smart cache and also supports DDR4-2666 and Intel Optane Memory. The i5-8600K features a base clock speed of 3.6GHz up to 4.3GHz, while the non-K i5-8400 features a base clock speed of 2.8GHz up to 4GHz. The Core i5-8600K comes with an MSRP of $257 USD, while the Core i5-8400 is priced at $128 USD.

Finally, the Core i3 series is now built with 4 cores and 4 threads; and 6MB of smart cache. The Core i3-8350K features a base clock speed of 4GHz and the non-overclockable Core i3-8100 features a base clock speed of 3.6GHz. Both Core i3 CPUs don’t feature Intel Turbo Boost 2.0 though. Core i3-8530K features a TDP of 91W, while the i3-8100 only has a TDP of 65W. Both CPUs support Intel Optane memory, and dual channel DDR4-2400 memory. They are also priced at $168 and $117 respectively.

According to Intel, these CPUs are designed for “powerful, fluid and vivid gaming”; and for advanced content creation. An excerpt from the news release can be read below.

Powerful, Fluid and Vivid Gaming
Gamers will revel in the powerful and fluid experience of gaming. Compared with 7th Gen Intel Core, gamers gain up to 25 percent more frames per second3 on popular and demanding games like Gears of War* 4. As gaming continues to expand to include a social audience while playing, performance while mega-tasking is critical so game + stream + record is now up to 2 times faster5 compared with a 3-year-old machine.

Advanced Content Creation
Save time and create more. The 8th Gen Intel Core desktop processor family positions Intel as the choice for speed, accuracy, power, format compatibility and high-quality graphics creation and consumption. Edit 4K 360-degree videos with ease – up to 32 percent faster6 compared with the previous generation – plus, edit content up to 65 percent faster4 compared with a 3-year-old PC.

Better Overclocking
Performance matters with overclocking. The 8th Gen Intel Core unlocked1 “K” processors will overclock to higher levels than prior generations. Intel has added new features to enhance the experience, including per core overclocking, max memory ratio up to 8,400 MT/s, real-time memory latency control, extended PLL trim controls, enhanced package power delivery, and updated Intel Extreme Tuning Utility and Intel Extreme Memory Profile.

Enhanced Platform
For the platform, the new Intel Z370 chipset provides improved power delivery needed for the new 6-core processors to reach their maximum performance as well as enhanced package power delivery for overclocking and memory routing support. More than 50 new motherboard and system designs will be available from a variety of leading providers.
