It should not be forgotten that Intel’s Alder Lake-S will be a transitional platform but that it will also be a turning point for PC architectures; not only is this platform the first to use DDR5 RAM memory or potentially the interface PCI-Express 5.0Rather, it will be the first hybrid desktop platform with “big” and “small” cores that will dramatically improve efficiency.
This is the Intel Core i7-12700K Alder Lake-S for desktop PC
Features of Intel Core i7-12700K Desktop Processor 12 hearts and 20 threads process (and not the 24 threads with which the software seems to have detected the CPU), because remember that this is a heterogeneous CPU and that the “small” cores do not have hyper-Threading
The sample presents 12 physical nuclei, of which 8 will be Golden Cove high performance and the other 4 will be Goldmont low consumption; Recall that the Golden Cove cores, the “big” ones, have hyperthreading and therefore have 16 processing threads, to which we must add 4 other Goldmont cores which lack Hyperthreading, so as we mentioned previously the total sum is 12 cores and 20 process threads.
As for clock speeds, and since it looks like the database reflects an engineering sample, we are faced with a base frequency of just 1.2 GHz with a boost frequency of 3.4 GHz. , although the way you will understand the end-of-run speeds of this processor will be much higher once the commercial model is on the street (speeds of about 5 GHz

– 12C 20T (wrongly declared as 24T)
– 8 * 1.25 MB + 4 * 384 KB = 11.5 MB L2
> L2 cache is reported as 9 cores, I think it’s just due to 4 small cores = 1 cluster. The reference point could recognize the cluster unit.
– 8 * 2.75 MB (cut from full 3 MB) + 4 * 768 KB = 25 MB L3 https://t.co/fO84Bz2qM3

In reference to hidden, the first thing to say is that the current software is not up to date to fully recognize hybrid processors (which is why it reports 24 threads, for example), so the software displays it for 9 cores for some reason. which means that the software reads it correctly for the 8 Golden Cove cores but then the 4 Goldmont cores puts them in the same drawer. Thus, 1.25 MB per core is displayed when this is not the case.
The “big” cores contain a 1.25MB cache while the “small” cores contain 2MB of shared cache per 4-core cluster, so the cache count matches previous rumors that placed the Alder Lake Core i7-12700K -S in 25 MB L3 cache total.
These are the preliminary specifications of the main processors of the generation, but remember that there is no data confirmed by Intel at the moment and therefore these specifications are not final.
