Today, the Intel announces the first processors 12th generation Core - 'Alder lake', which use Intel hybrid technology, offering both large and small cores.
ΑThese new processors are made with technology Intel 7 node (7nm), formerly called Enhanced SuperFin.
Of course, the idea of having large and small cores in the same Chip at the same time is not new, as the ARM Has been applying it to its own chips for years. The idea is that tasks that require more power can use these large and efficient cores, while tasks that do not require as much power can use small CPU cores, thus saving a large amount of power.
This is a smart way to improve battery life on mobile devices and smartphones, which has been widely used for many years. The last and only time that the Intel showed us its hybrid technology was with them Lakefield.
Intel Hybrid Architecture and Intel Thread Director
So today three main processors are announced, which will have the corresponding ones K and KF their variants. The F at the end of their name will mean that they do not have built-in graphics. The youth Core i9-12900K, Core i7-12700K and Core i5-12600K CPUs will have 16, 12 and 10 cores. From these nuclei the Core i7 and Core i9 will have eight small nuclei (energy efficient), while the Core i5 will have six small nuclei.
Now the question arises, why does this hybrid technology apply to a chip aimed at desktops (PCs)?
The answer is quite simple: To increase performance especially in Multi-Threading, while at the same time consuming less energy.
The more cores on a Chip will mean more performance, and Intel Thread Director will be able to intelligently direct the work to the appropriate threads (note that large cores are Hyperthreaded, while small nuclei do not).
With Intel 12th generation chips, there will be two classes of CPU cores called P-cores (Power - Cores - large cores) and E-cores (Energy Efficient Cores). The workload required by games and various productivity applications will be directed to the cores P, while E-cores will handle workloads for applications that need a lot of threads (Threads) but also tasks that run in the background.
Intel promises one increasing yield by 19% with the nuclei P. But that is not all. The youth P cores will offer against 28% improvement in IPC in relation to "Comet Lake10th generation, but even the E cores will offer 1% improvement.
The improvements that the news will bring Intel Alder Lake platform, do not stop here. New improvements to Intel's new platform include support for DDR5 memory and PCIe 5.0. New PCIe 5.0 doubles its speed PCIe 4.0 and reaches it at 32 gigatransfers per second.
There is also the new Intel Z690 chipset , which has built - in support for 12 PCIe 4.0 lanes, which can provide support for 16 PCIe 3.0 lanes and for total 28 PCIe lanes coming out of the chipset. In the same Chipset there is also built-in support for USB 3.2 Gen 2 × 2 and Wi-Fi 6E.
The processors 12th generation of Intel need the new LGA 1700 socket, but this is not surprising, given how drastically the architecture of the new CPUs has changed.
Prices start at $ 264 for the Core i5-12600KF and reach $ 589 for the Core i9-12900K.
