We're essentially seeing a fundamental change in the way Intel is classifying its low-powered mobile processors in the 9/15/28W power brackets. These U-series processors will directly be replacing the older 12-28W chips like the Core i7-1185G7, for instance. At 15W, we have a design that's very similar to the older U-series processors that we're familiar with. This particular design combines both the CPU and the chipset on the same package, and it's the smallest package that Intel offers right now. Starting with the low power processors at 9W, these are essentially the same as the ultra-low-power Tiger Lake processors that use BGA Type4 or UP4 Intel design. The U-series, on the other hand, has both 9W and 15W processors. We suggest you keep an eye on the ultrabook designs from manufacturers including HP, Lenovo, Dell, and even Microsoft, as we expect one of these P-series chips to end up in one of the new Surface laptops sooner or later. These processors all have the 'P' suffix in their name and you'll see a lot of them in the high-end ultrabook market. There are six P-series processor designs in total ranging from a Core i7 to Core i3 with different hybrid core configurations. It's a pretty cool laptop with a very unique design and some other interesting features. Be sure to check out our Dell XPS 13 Plus hands-on article while you are here. Laptops like the new Dell XPS 13 Plus will be powered by the P-series processors. These processors will be powering the performance thin and light notebooks in 2022 and beyond. We now have the Intel 12th-gen Alder Lake P-series with 28W processors with BGA Type3 or UP3 package size. Well, Intel is changing that with the 12th-gen Alder Lake mobile chips. These processors scale starting with dual-cores 9W chips, all the way up to quad-core 28W chips based on the configuration. We're used to Intel typically addressing the ultraportable laptop chips as its U-series processors, meaning all processors powering these notebooks have U in the product name. So in this article, we're going to take a look at the comparison between Intel 12th-gen P-series vs U-series mobile CPUs for laptops to find out the key differences between the two lineups: Understanding the product name: P-series vs U-series While Intel's CES 2022 keynote mainly focused on the 45W H-series designs, there's a lot happening this time in the ultraportable low-powered CPU space too.
