A well-known informant with the pseudonym HXL has revealed the technical features of a series of 12th generation Intel Core mobile processors. Alder Lake chips will be built on a hybrid architecture of large performance and small energy efficient cores. The manufacturer has already implemented a similar approach in Lakefield mobile chips for ultra-portable laptops. The future mobile family of Alder Lake has 19 models ranging from low-power to high-performance.

According to the informant, the Alder Lake M series of chips will consist of the M5 and U9 models. These processors are designed primarily for tablets and ultrabooks and have TDP values ​​of 5W and 9W, respectively. The first will use one large core and four small ones. In the second, there are two large and eight small energy efficient cores.

The Alder Lake P series will include the U15, U28 and H45 models. The first will use two large and eight small cores. The TDP level of the chip will be 15 W. Models U28 with a TDP of 28 watts will receive six performance and eight energy efficient cores. The H45 variants will replace the current Tiger Lake-H35 and offer up to six large and up to eight small processing cores. The main segment of these processors is portable gaming laptops. Most of the processors described here will have an integrated graphics core with 96 execution units (EUs).

The oldest and most productive representatives of the mobile part of the Alder Lake family will be the Alder Lake-H55 models with a TDP level of 45 to 55 W. These chips will use configurations with up to eight large and eight small computing cores. In addition, Alder Lake-H55 will receive an integrated graphics core with only 32 execution units, which is not surprising, because they are clearly designed to work with powerful discrete graphics cards.

Intel Alder Lake mobiles will be powered by a combination of high-performance Golden Cove cores and energy-efficient Gracemont cores. For their production, a 10-nm process technology will be used. Large cores (Golden Cove) should provide 20 percent IPC gain over Willow Cove in the Tiger Lake series.

Intel is rumored to be expecting an overall increase in IPC (number of instructions per clock) from 16% to 18% for the new chips. The company will also release Alder Lake desktop chips with core configurations similar to the older mobile Alder Lake-H45 and H55. That is, in the desktop segment, you can count on chips that will offer up to eight large and eight small cores. Early rumors attributed the 12th Gen Intel Core processors support for DDR5 RAM as well as the new PCI Express 5.0 bus.
