Cores
Cores	Zen 3; Vermeer.	Cascade Lake-X; Hyper-Threading and an unlocked multiplier, confirmed by Intel’s exact-model family product brief.
Clocks
Clocks	Unlocked for overclocking; Precision Boost 2 and Precision Boost Overdrive described in AMD's launch notice.	Turbo Boost Max 3.0 up to 4.80 GHz on the preferred cores; ordinary Turbo Boost 2.0 up to 4.60 GHz. Intel targeted November 2019 availability, and Newegg records this exact SKU first listed on 25 November 2019. A listing date alone does not establish first actual sale; conservative year precision is retained.
