Intel is making a difference with non-K versions of Alder Lake

Summary: In previous generations, Intel K and non-K processors mainly differed in overclocking potential: the former allow it, and the latter do not. Depending on the model, Intel also lowered the frequency of the non-K version to anywhere from hundreds of megahertz to gigahertz.

Something is wrong with non-K versions of Alder Lake. In case you haven’t noticed, they haven’t been released yet – the delay has only happened once in the last five generations. And according to the user DDAA117which accurately leaked the K processor specifications earlier this year, non-K versions will periodically have large deviations from their counterparts.

Between the veteran leader Momomo, erroneous retailer lists, and DDAA117, there is a pretty clear idea of ​​non-K processors. Indeed, there are even real images of the i9-12900, i5-12600, i5-12500 and i5-12400.

At the top of the heap, the 12900 occupies a pretty comfortable place as an Intel processor, outperforming non-overclocking users. It doesn’t lose much to its K-counterpart; it has the same 8P + 8E core configuration and only loses 100 MHz at the boost clock speeds of its cores and 1 GHz at the base clock speeds.

It’s the same with the 12700, except that it loses 1.5 GHz at its base frequency.

In the meantime, 12600 loses a lot. It uses mid-range Alder Lake silicon with no effective cores, while the 12600K uses high-end silicon with four out of eight active cores. Thus, the 12600 has a total of six high-performance cores, while its counterpart is 6P + 4E. The performance core clock is also 100 MHz lower, and the base clock is 400 MHz lower.

There are no K versions of the 12500 and 12400 to compare them with. As standalone processors, they’re pretty good on paper. All three non-K i5 models have the same six performance cores and differ only marginally in clock speeds. 12500 has a frequency of 4.6 / 3.0 GHz and 12400 has a frequency of 4.4 / 2.5 GHz.

12400 makes rounds. An engineering sample of the F version of the processor has been tested by a French reviewer, and it has fiercely competed with the AMD Ryzen 5600X. It was also listed two retailers, one of whom named the price of vanilla and the F version; $ 224 and $ 194 respectively.

While another retailer did not provide a price, he stated that he has both 12,400 and 12,700 in stock. To be honest, and retailers are getting shipments from Intel, Intel could be gearing up for an imminent release. Leaders (and Logic) say they could launch in mid-January following the announcement at CES 2022 during Intel’s January 4th presentation.
