Intel Core i5-12400F and i3-12100F are the first Alder Lake-S CPUs not to feature any Efficient cores.
According to the marketing materials received for the upcoming Alder Lake-S non-K series CPUs, the 12100F, 12400F, and 12700F are representatives from each of the 12th Gen Core Alder Lake sub-series. These CPUs come with the Laminar RM1 stock cooler rated for 65W TDP.
A Leaker claims that Core i3-12100F will be equipped with 4 cores and will feature 8 threads. This is a typical configuration for a high-end CPU. Previous leaks suggest that it will boost up to 4.3 GHz.
We also have all the information about Core i5-12400F and i7-12700F. The first CPU will feature 6 cores along with 12 threads. This tends to be the complete implementation of the second Alder Lake desktop silicon variant(named H0). The i7-12700F will have similar features to the already-released K variant, except for having a lower frequency and TDP. The Performance cores are said to boost up to 4.9 GHz(100 MHz lower than 12700K).
Many more of the Alder Lake CPUs are expected to launch in January, just after the official CES 2022 conference.
