Base clock
Base clock	3.7 GHz	2.9 GHz
Boost clock
Boost clock	4.8 GHz (better)	4.4 GHz
L3 cache
L3 cache	64 MB (better)	16.5 MB
Cores
Cores	Zen 3; Vermeer. Two CPU chiplets with six active cores each (PC Gamer).	Skylake-X; 12 cores with Hyper-Threading. The unlocked multiplier is confirmed by Intel’s exact-model family product brief.
Clocks
Clocks	Unlocked for overclocking; AMD's launch notice describes Precision Boost 2 and Precision Boost Overdrive.	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.
Cache
Cache	6 MB L2; Zen 3 unifies each eight-core complex around 32 MB of L3 cache, as described in AMD's launch notice.	16.5 MB Intel Smart Cache (L3).
