L3 cache	9 MB	36 MB (better)
Cores
Cores	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.	8 Performance-cores and 16 Efficient-cores, with Hyper-Threading; codename Raptor Lake
Clocks
Clocks	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.	P-core base 3.2 GHz, max turbo 5.6 GHz; E-core base 2.4 GHz, max turbo 4.4 GHz; Turbo Boost Max 3.0 5.8 GHz; Thermal Velocity Boost 6 GHz
Cache
Cache	–	36 MB Intel Smart Cache (L3); 32 MB L2

Memory support	Up to 128 GB; two channels; DDR4-2666; 41.6 GB/s maximum bandwidth; ECC not supported.	Up to DDR5 5600 MT/s or up to DDR4 3200 MT/s; 2 channels, up to 192 GB; ECC supported
PCIe
PCIe	PCIe 3.0; 16 CPU lanes, configured as 1×16, 2×8 or 1×8+2×4.	PCIe 5.0 and 4.0; 20 lanes (Up to 1x16+4, 2x8+4); DMI 4.0 x8
Chipsets
Chipsets	–	Intel 600 and 700 series
Process
Process	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.	Intel 7
Cooler
Cooler	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.	max operating temperature 100 °C; thermal specification PCG 2020A
