Clocks
Clocks	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.	Turbo Boost Max 3.0 up to 4.80 GHz on the preferred core; ordinary Turbo Boost 2.0 up to 4.60 GHz. The main boost field uses Intel’s highest published frequency. Intel targeted November 2019 availability. Scan’s dated 26 November guide confirms that this exact processor was available to purchase; the exact maker-confirmed first-sale day remains unverified, so month precision is retained.
