Intel is reportedly settling for 6P+4E as the CPU core configuration for its upcoming Core i5-14400 and i5-14400F desktop processors. That's 6 performance cores or P-cores, and 4 efficiency cores or E-cores. Two distinct engineering samples of the i5-14400 were spotted in the wild, one of which had a 6P+4E configuration, and the other believed to be with 6P+8E, like the rest of the 14th Gen Core i5 series. There are two distinct steppings of the i5-14400 among the engineering samples, besides the core-configuration, B0 and C0.
What differentiates B0 from C0 is the specific die they're based on. B0 is the larger "Raptor Lake-S" die that physically has 8 P-cores and 16 E-cores, which has been significantly cut down to achieve the 6P+4E configuration; whereas C0 is the die the "Alder Lake-S" top-spec processor models were based on, which physically have an 8P+8E configuration. Both B0 and C0 Core i5-14400/F processors have 6P+4E. The P-cores on both steppings, including B0, are configured with 1.25 MB of dedicated L2 cache, the E-core clusters on both each have 2 MB of L2 cache; and both get 20 MB of shared L3 cache, and 65 W of processor base power. The Core i5-14400 and i5-14400F succeed a long line of successful processor models for Intel, positioned around or below the $200 mark.
