CoresSix cores without Hyper-Threading; Intel Turbo Boost 2.0 supported. Intel's F suffix denotes a processor requiring separate graphics; its multiplier is locked.Raptor Lake; 8 Performance-cores with Hyper-Threading and 16 Efficient-cores
ClocksMaximum 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.P-core base 3.2 GHz and turbo 5.7 GHz; E-core base 2.4 GHz and turbo 4.5 GHz; Turbo Boost Max 3.0 5.9 GHz; Thermal Velocity Boost up to 6.2 GHz

Memory supportUp to 128 GB; two channels; DDR4-2666; 41.6 GB/s maximum bandwidth; ECC not supported.Up to 192 GB; two channels; DDR5-5600 or DDR4-3200; ECC support depends on the motherboard and configuration
PCIePCIe 3.0; 16 CPU lanes, configured as 1×16, 2×8 or 1×8+2×4.20 CPU lanes; PCIe 5.0 and 4.0
Chipsets–Intel recommends Z790 or Z690 with the latest BIOS
Process14 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.Intel 7
CoolerBoxed 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.Maximum operating temperature 100 °C; maker maximum turbo power 253 W. The 320 W Extreme profiles used in launch reviews are separate operating configurations.
