Intel has introduced its hybrid desktop processor family

The 12th generation Core CPUs are based on the Alder Lake-S chip, but only the more expensive models can be expected in the first round.

Intel has also officially unveiled its new family of desktop processors, which will be the 12th generation Core series. The chip, codenamed Alder Lake-S, housed in a new LGA1700 socket enclosure, uses Intel 7’s 10nm manufacturing technology and has been talked about by the company before, so its design can’t be new.

In the linked news, the technical data is explained, so we would not repeat them again, but there is also officially confirmed fresh data, so it is already known that 3200 and 4800 MHz, respectively, are the officially supported maximum effective clock for DDR4 and DDR5 memories. It is up to the buyer to decide which memory standard to choose, obviously the motherboard looks great in this.

For the platform, you can first choose the Z690 control bridge, which can be seen as an upgrade to the Z590, including slightly more PCI Express 4.0 tracks, better device management, integrated Wi-Fi 6E, and DMI 4.0 links. The latter connects the chip to the processor, but the number of tracks remains eight. In terms of interfaces, an innovation is that four USB 3.2 Gen2x2 can now be unplugged. Of course, a lot of things here depend on how the motherboard manufacturers use the features, it is better to start with the specifications of the selected motherboard instead of the general data.

The parameters for the first round of 12th generation desktop Core processors are detailed in the table below:

A big change is that Intel drops the TDP parameter when determining consumption. Instead, the company gives each processor the base (PL1) and maximum (PL2) power consumption, respectively. The default value is closest to what the TDP consumption frame used to mean, but the operation of the system already depends on settings. If the so-called PL1 and PL2 consumption values ​​do not match, then during the load exerted by a program, the processor switches to the turbo clock signals, and therefore its consumption increases to a maximum for a short time. With this, the hardware starts to warm up and after a while reaches a temperature after which it can no longer keep the initial speed pace. All of this, of course, depends on the application, and more importantly, there is also a time limit on the turbo clock, which is around half or a minute, depending on the model. If the hardware crashes into one of the many limitations, its consumption will return to default. This obviously drops the powerful turbo, but it doesn’t even eat up energy in an extreme way, and it can work in this form for as long as possible.

An alternative mode of operation is when the fuel consumption value PL1 is the same as the default parameter PL2, which means that the turbo will no longer be tied to a limited duration, depending on the model, half or one minute. In this mode, only the temperature determines how the system responds to the conditions, and if the processor can stay cool enough at the maximum power setting, it will remain operational at significantly higher power requirements than the base, allowing the turbo to stay strong for longer.

It is important to note that for Ks processors, Intel will offer the mode of operation described in the last paragraph by default, while for later non-Ks models, the operation described in the previous paragraph will apply. All this is of great importance, because from this point of view it is best to look at the maximum consumption parameter on a Ks processor, while in the case of non-Ks developments, the default value is especially important. It is also important to pay attention to the fact that the operating range of the processor is only one thing, motherboard manufacturers also need to design a motherboard so that it can permanently serve up to 241 watts of power. However, it is already known that only the most expensive boards will be able to do this, and because of this, the performance of the Ks Core i5, i7 and i9 models is very much determined by the motherboard chosen.


According to information from the manufacturers, Intel imposes a mandatory 135-watt persistent load limit, so this must be met by all motherboards, but in so-called more restrained products, Ks Core i5, i7 and i9 processors will be much slower than in poison-expensive high-end hardware, after all, Core i9 model will not be able to pick up 241 watts, even though it could do it in theory. Instead, it has to reach a 106-watt narrower frame, which significantly degrades its performance. So it’s a good idea to pay attention to this at the time of purchase, because if you want maximum speed for the Ks Core i5, i7 and i9, you shouldn’t spend a dime on Z690 motherboards, otherwise the motherboard won’t be able to handle the enduring power requirements of the processor itself, and it won’t even bring you home at the pace you do in test labs operating with topsheets.

Apparently, Intel assumes here that a potential buyer who has money for a Core i7 or i9 is aware of their consumption anyway, so they will buy a serious water cooler for them, offering them with a very powerful power supply, and if these you can pay for poison expensive components individually, you probably won’t save on the motherboard. In any case, if someone still wanted to save the budget here, don’t do it because overall it is worse off than buying a cheaper processor.


Because the new processors consume a lot of power, Intel doesn’t even come with a factory cooler, so you’ll need to purchase one separately. It is highly recommended, but not required, to purchase water cooling for each model. However, without water cooling, performance can be significantly reduced as the insert reaches maximum temperatures sooner, so you will need to take the turbo back even if in theory it would still be possible to set a higher clock. Here, the situation is pretty much the same as in the case of motherboards, only it is not the power supply but the provision of good temperature values ​​that is the critical factor.

The processors just introduced will be available for purchase on November 4th.
