Cores
Cores	Zen 2; Matisse; eight cores with simultaneous multithreading. One CPU chiplet containing two four-core complexes and a separate I/O die (PCGamesN).	Six cores without Hyper-Threading; Intel Turbo Boost 2.0 supported. Intel's F suffix denotes a processor requiring separate graphics; its multiplier is locked.
Clocks
Clocks	Unlocked for overclocking; Precision Boost Overdrive with Automatic Overclocking supported, as described in AMD's launch notice.	Maximum turbo is a single-core frequency; sustained clocks depend on cooling and motherboard power settings. Intel publishes TDP without a separate maximum turbo-power figure.
Cache
Cache	512 KB L1; 4 MB L2; 32 MB L3.	–

PCIe
PCIe	PCIe 4.0 x16; AMD introduced PCIe 4.0 support with the X570 platform at launch.	PCIe 3.0; 16 CPU lanes, configured as 1×16, 2×8 or 1×8+2×4.
Chipsets
Chipsets	X570 at launch; check the motherboard's CPU support list and BIOS for other AM4 boards.	–
Process
Process	TSMC 7nm FinFET CPU cores; 14nm I/O die (PCGamesN).	14 nm; Coffee Lake; 37.5 × 37.5 mm package; 100°C maximum junction temperature. ComputerBase identifies a paste thermal interface on its launch sample; this should not be assumed for every later stepping.
Cooler
Cooler	Retail boxed processor includes AMD Wraith Prism (PCGamesN); AMD's current support specification does not name a cooler. Maximum operating temperature 95°C.	Boxed cooler included and tested by TechSpot. Intel 300-series motherboard compatibility requires the appropriate BIOS and vendor support. Intel's January release notice gives a late-January through first-quarter rollout for the new models; IT Home reports the exact 9400F on sale in China on 28 January, supporting month precision rather than a confirmed worldwide first-sale day.
