Intel's 12th Gen 'Alder Lake' Will Be its First 10nm Desktop CPU Lineup in 2021, Big.Little Core Setup Rumoured

Along with the news that its future 7nm CPUs will be delayed till at least late 2022, and that it might pivot to contracting external fabs for manufacturing, Intel also confirmed part of its roadmap going forward. The key takeaway is that Intel is not planning to ship 10nm CPUs for the desktop segment until its 12th Gen platform, which is expected to be ready in the second half of 2021. The company also confirmed the codename 'Alder Lake' as the 12th gen platform for the mobile and desktop segments. It will follow the 11th Gen 'Tiger Lake', which is expected to be launched in September this year, but will likely only be available for some segments of the laptop market, like current 'Ice Lake' processors. No specifics about the capabilities and configurations of Alder Lake CPUs were announced.

However,Alder Lakehas been the subject of severalleaks and rumours, suggesting that at least one desktop implementation will be a hybrid configuration built using large 'Core' as well as small 'Atom' CPU cores. This would follow the recentlaunch of Intel's 'Lakefield' CPUs, which aremarketed as Intel Core CPUs With Hybrid Technology.

According torumours published by WCCFTech, Intel could be planning to ship desktop Alder Lake with as many as eight powerful 'Golden Cove' cores and eight efficient 'Gracemont' cores, with different configurations for different PC and possibly server segments. Lakefield has been promoted as a solution for extremely portable devices for which battery life is a major consideration. A hybrid core design would delegate lower priority background tasks and sensor activity processing to the lower-power efficiency cores, reducing overall power consumption.

Intel'sHybrid Technology implementation so far allows it to mix and match various different kinds of technology blocks such as CPU and GPU cores, as well as IO processing and special-purpose logic. It is likely that Alder Lake will also leverage Intel'sFoveros 3D stackingmanufacturing process. Previous rumours also suggest that Intel will introduce DDR5 RAM and anew LGA1700 socketwith this generation.

The delay of 7nm parts follows Intel'syears-long struggleto ship 10nm CPUsin volume, resulting in anunprecedentedly longlife span for the 14nm node. It is not known how this will affect the company's roadmap beyond Alder Lake. Meanwhile, competitorAMDhas beenshipping 7nm Ryzen CPUsin volumefor a year now, and is expected to migrate to 5nm in 2021 or 2022.
