Intel indirectly announced an 8 core Cannonlake CPU over 2 years ago in a job posting. Why is there any speculation what process it will be? Cannonlake mobile chips were originally supposed to be released in q3 of last year, with desktop variants this year. The delay in 10nm forced Intel to add Kaby Lake (
skylake refresh probably became coffee lake).
All the AMD people who think Intel is releasing high core CPU's now because of AMD, don't understand how CPU development works. It's not AMD that has Intel scrambling, it's Intel's inability to execute their own roadmap that has them making all these disjointed and nonsensical partial generation releases. Intel had Cannonlake on their roadmap back in 2013, and knew there would be an 8 core version no later than summer 2015 which makes it impossible for it to be a response to unknown at the time Ryzen and completely contradicts people saying we wouldn't have gotten higher core CPU's from Intel if not for AMD. If the plan had gone to schedule we'd already be on 8 core Cannonlake now with 6 core Coffee Lake being released q3 of last year.
