L3 cache	20 MB	24.75 MB (better)
Cores
Cores	6 Performance-cores and 4 Efficient-cores, with Hyper-Threading; codename Raptor Lake	Cascade Lake; 18 cores with Hyper-Threading. The unlocked multiplier is confirmed by Intel’s exact-model family product brief.
Clocks
Clocks	P-core base 2.5 GHz, max turbo 4.7 GHz; E-core base 1.8 GHz, max turbo 3.5 GHz	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.
