Cores
Cores	6 P-cores and no E-cores; 12 threads. Intel Thread Director is not supported.	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	2.5 GHz P-core base, up to 4.4 GHz P-core turbo; locked multiplier confirmed by io-tech and TechPowerUp.	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.

Process
Process	Intel 7; Alder Lake; FCLGA1700, 45 × 37.5 mm package; 100°C Tjunction.	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	Intel Laminar RM1 included with boxed retail processor (Intel support).	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.
