L3 cache	36 MB (better)	16.5 MB
Cores
Cores	8 Performance-cores and 16 Efficient-cores, with Hyper-Threading; codename Raptor Lake	Skylake-X; 12 cores with Hyper-Threading. The unlocked multiplier is confirmed by Intel’s exact-model family product brief.
Clocks
Clocks	P-core base 3.2 GHz, max turbo 5.6 GHz; E-core base 2.4 GHz, max turbo 4.4 GHz; Turbo Boost Max 3.0 5.8 GHz; Thermal Velocity Boost 6 GHz	Turbo Boost Max 3.0 up to 4.40 GHz on the preferred core; ordinary Turbo Boost 2.0 up to 4.30 GHz. The main boost field uses Intel’s highest published frequency. Intel planned availability on 28 August 2017, but contemporary Tom’s Hardware reporting says retail availability followed roughly a week later. September precision reflects that actual-sale evidence rather than the earlier promised date; an exact first-sale day remains unverified.
