i7-14700K and i7-14700KF
So, enough speculation and back to the tangible binning data, this time with the i7 SKU. These are probably one of the most exciting CPUs of this generation, as unlike the i9 and i5 chips, they have also undergone a change in the number of cores, namely 4 extra E-cores. Incidentally, this is precisely why the i7 SKUs are the only ones that require a BIOS update. On the other hand, I was able to boot 14900 and 14600 chips in my Asus Maximus Z790 Hero with BIOS 0904 from March 2023 without any problems, but more on this in the IMC tests.
The SP values for the i7 and i5 chips are significantly lower, but this does not automatically mean less clock potential. The background to this is simply a different weighting for the VID values that Asus has stored in the BIOS. In addition, these CPUs have a lower maximum frequency, 5.6 GHz for the i7-14700K(F). Interestingly, the ratio of K to KF is reversed again here, so that the KF CPUs are on average over 5 SP better and are distributed up to a maximum total value of 85, even though we only tested 69 chips compared to 83 14700Ks. So is Intel planning a 14700KS and holding back good 14700K silicon?
With the P SP values you can see again where the distribution in the total SP comes from. The most frequently occurring P SP value for the 14700KF is even higher than the highest value for the 14700K. That is very strange. But again, please take this with a pinch of salt, as our test set is probably too small to be representative.
The diagram with the VID values for the maximum frequency is included here as the distribution is very similar. However, you can also see here that the occurring VID values do not follow each other as evenly in 5 mV steps as with the i9. Here it can sometimes be only 1 mV, but sometimes 10.
Even with the i7 chips, the distribution of the E SP values is still the most bell-shaped. With a spread of 31 values, it also shows that the quality of the E cores seems to become increasingly irrelevant as the clock rate decreases. They only boost up to a maximum of 4.3 GHz in the i7 as opposed to 4.4 GHz in the i9.
Finally, you get the batch bubbles. Is a counter with “P” and a high number almost an “R” batch, according to the motto “the later in the alphabet the letter, the better”? Would a “Z” batch then be best? Well, let’s take off the tin foil hat again.
