Cores and clocks
Cores14 (6 performance, 8 efficiency)6
Threads206
Base clock2.6 GHz2.9 GHz
Boost clock5 GHz4.1 GHz
L3 cache24 MB9 MB
Cores6 P-cores and 8 E-cores; 20 threads. ComputerBase identifies its tested sample as C0 Alder Lake silicon within the marketed Raptor Lake Refresh generation.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.
ClocksP-cores: 2.6 GHz base, up to 5.0 GHz turbo. E-cores: 1.9 GHz base, up to 3.7 GHz turbo.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.
Cache24 MB Intel Smart Cache (L3); 11.5 MB total L2.–

ChipsetsIntel 600- and 700-series motherboards; appropriate BIOS support required.–
ProcessIntel 7; Raptor Lake Refresh generation. ComputerBase identifies the tested sample as C0 Alder Lake silicon. 45 × 37.5 mm package; 100°C maximum junction temperature.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.
CoolerIntel Laminar RM1 included with the boxed 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.
