  • Long wait. But 6 cores is good.

  • More news.

    Top model will be Core i7-8700K. It'll have 6 cores and 12 threads. Base frequency will be 3.7Ghz, 12Mb cache. All fits within 95 TDP.

    Core i7-8700 will be 3.2Ghz.

    Mode affordable will be Core i5-8600K , also six core model. 6 cores/6 threads. 3.6Ghz frequency.

    Lowest 6 core model will be Core i5-8400 with only 3.2Ghz.

    In mobile they will also have six code models, and U line will move finally to 4 core solutions.

    SANTA CLARA, Calif., Sept. 24, 2017 – Intel today announced that its new family of 8th Gen Intel Core desktop processors will be available for purchase beginning Oct. 5, 2017. The new desktop processor family is built for gamers, content creators and overclockers who require premium performance. Ranging from Intel Core i3 to Intel Core i7, these processors deliver premium performance for what comes next, opening the door for a new level of faster, easier and more immersive experiences.

    This new family introduces the first-ever 6-core Intel Core i5 desktop processor and first-ever 4-core Intel Core i3 desktop processor. The family offers a wide range of performance options for consumers with unlocked1 “K” processors that deliver maximum tuning flexibility at each brand level and up to 40 platform PCIe 3.0 lanes for system expandability on graphics, storage and I/O. These processors are supported with new Intel Z370 chipset-based motherboards.

    The top of the product stack – the Intel Core i7-8700K – is Intel’s best gaming desktop processor ever.2 It is capable of 4.7 GHz maximum single-core turbo frequency, the highest frequency ever from Intel thanks to Intel® Turbo Boost Technology 2.0, making it a performance powerhouse for both single and multi-threaded applications.

    “We are laser-focused on giving the enthusiast community the ultimate desktop experience, from chart-topping performance to a platform that can flex with their needs,” said Anand Srivatsa, general manager of the Desktop Platform Group at Intel. “Our 8th Gen Intel Core desktop processors deliver tremendous improvements across the board and – for gamers, in particular– offer an unbeatable experience.”

    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 faster compared with the previous generation – plus, edit content up to 65 percent faster 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.

    Launch games and load media projects faster. Add Intel® Optane™ memory to desktop computer with an 8th Gen Intel Core processor to gain additional accelerated system responsiveness, up to 2.1 times faster7 compared with a 5-year-old desktop with HDD alone.

    8th Gen Intel Core desktop processors will be available beginning Oct. 5, 2017.

  • Are there any significant differences in the media capabilities (Quick Sync) of Coffee Lake compared to Kaby Lake processors?

    Kaby Lake already had support for 10-bit HEVC/VP9 decode, 10-bit HEVC encode and Rec. 2020, HDR as described here:

    So, it's not clear that Coffee Lake actually has anything new in this area.

  • @davedv

    I do not see new thing being mentioned for now.

    NLE authors actually got mostly stuck with QuickSync, instead of allow users to make cheap upgrade by simple changing GPU and rely on Nvidia library.

  • At $600 the 7820 looks like a pretty good chip. The mainboard won't be cheap, but live playback and export times are excellent.
