These new processors were first announced at CES 2022 and sit under the top-of-the-range Alder Lake H-Series in Intel’s lineup. Instead of operating at 45-watts like the H-Series, the mid-range P-Series operates at 28-watts. The entry-level U-Series comes in two variants operating at 15 and nine-watts. Like all Alder Lake CPUs, the mobile range uses Intel’s hybrid architecture with P-cores for performance-related tasks and E-cores for less intensive background tasks.
There are six P-Series variants on offer with three i7s, two i5s, and just one i3 in the lineup. The range-topping i7-1280P comes with six P-cores that operate between 1.8 GHz base and 4.8 GHz boost, and eight E-cores working between 1.3 and 3.6 GHz. It also has 24 MB of L3 cache and 1.45 Hz graphics frequency.
Sitting at the bottom of the range is the i3-1220p with two P-cores operating between 1.5 and 4.4 GHz and eight E-cores working at 1.1 and 3.3 GHz. It also has a lower 12 MB of L3 cache and a maximum graphics frequency of 1.3 GHz.
The U-Series includes two i5 and i7 models as well as a single i3 with a Pentium and Celeron chip rounding off the lineup. Its range-topping i7 features two P-cores operating between 1.8 and 4.8 GHz and eight E-cores operating between 1.2 and 3.5 GHz. It has the same 12 MB L3 cache as the entry-level P Series i3-1220p with a lower 1.25 GHz graphics frequency.
Entry-level Intel laptops will feature the Celeron CPU with just a single P-core operating at 1.1 GHz and four E-cores operating at 0.9 GHz. This CPU also has 8 MB of L3 cache and a 1.1 GHz graphics frequency.
