Intel to Settle for 6P+4E as Core Config for Core i5-14400

[btarunr]

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.

I do have friends that buy these and are happy they they don't need windows 11, ahhh are they in for a funny story with this, they won't be happy for when they need to upgrade

Fewer e-cores are preferable for the basic i5 imho. But whilst early rumors swowed an (expected) boost clock of 4,8GHz, newer rumors suggest 4,7GHz, i.e. only 100MHz above 13400. Seems somehow pointless.

It would be good if they improve the lower lines a bit, i3 and "300" (ex Celeron and Pentium I guess), they seem too limited in the way they are now.

I want a 8-P-core model. How simple is this?

The problem is you pretty much never see these boost clocks, unless you enable ALL power saving features and use affinity.

Most of the time you'll only see 4.1 GHz on the 13400, which probably means 4.2 or 4.3 on the 14400. It's fine at these prices, but still underwhelming, especially compared to the Ryzen 7600.
