Intel is expanding its 12th Gen ‘Alder Lake' U family with two new ranges, aimed at slim and light laptops for mainstream s. After launching the generation with high-end gaming laptop Us at CES in January, Intel is now ready to address a much larger market segment. The ‘Alder Lake' generation combines heterogenous X86 P-cores and E-cores (for power and efficiency) to the mass market for laptops for the first time, along with Intel Xe graphics. 3j2s2m

According to announced at CES. Performance is said to be greatly improved in workloads that benefit from high core and thread counts, such as 3D rendering, photo editing, and general productivity while multitasking.

The P-series is a new designation within Intel's usual hierarchy and will address the 28W “enthusiast thin-and-light” segment. Six models have been announced, across the Core i3, Core i5, and Core i7 tiers. The rise in thread counts is said to deliver enthusiast-level performance and improved productivity. While the Core i3-1220P has two P-cores with Hyper-Threading and eight E-cores, the total count goes up to six P-cores with Hyper-Threading and eight E-cores on the top-end Core i7-1280P. Laptop OEMs will also be able to leverage up to four Thunderbolt ports and partially integrated Wi-Fi 6e.

The refreshed U-series will be available in two different package sizes to address the 9W segment for extremely portable devices and 15W TDP segment for everyday s. There are seven new models in each category, ranging from Celeron (one P-core, four E-cores, no Hyper-Threading) to Core i7 (two P-cores, eight E-cores, 12 total threads).

Intel says its latest Us use the same Thread Director feature as the previously released 12^th Gen Us. This helps assign workloads dynamically between P-cores and E-cores based on power and performance requirements, and is integrated into Windows 11. Windows 10 is also compatible, but not as deeply optimised for the heterogenous core architecture.

DDR5 and DDR4 as well as LPDDR5 and LPDDR4X RAM will be ed for all Us except the 9W U-series models which only LPDDR5 and LPDDR4X. The smaller package also means slightly more limited IO, such as ing fewer USB ports, only two Thunderbolt 4 ports, and four PCIe 4.0 lanes for an SSD. The 15W U-series Us have the same IO as the 28W P-series, with for four Thunderbolt 4 ports and eight PCIe 4.0 lanes.
