If historical past is any information, your subsequent pocket book’s new processor launched right this moment, as Intel unveiled a recent lineup of 12th-gen Core CPUs for laptops—particularly the chips codenamed Alder Lake-P for mainstream notebooks, and Alder Lake-U for ultraportable PCs and tablets.
Intel ships about 80 percent of all notebook PC processors annually, that means that you simply’ll in all probability find yourself shopping for a pocket book PC with considered one of these new chips inside. In January, Intel announced the Alder Lake-H, Alder Lake-P, and Alder Lake-U sequence, as a part of Intel’s pocket book processor plans for 2022. Because of the best way wherein Intel rolls out its new chips, we have already got our first review of the 12th-gen Core i9-12900HK, a fire-breathing, gaming-class processor that crushed the (older) laptop computer competitors.
It’s much less possible, nonetheless, that you simply’ll buy a gaming laptop in 2022 than a extra mainstream system. Intel believes greater than 250 totally different laptop computer fashions will embrace these new P- and U-series chips, which have already begun delivery. Unfortunately, nonetheless, we don’t but have considered one of these new P-series or U-series notebooks in for testing, so we’ve as an alternative summarized what we all know of those new chips — together with the specs, options, and estimated efficiency — in our abstract under.
Don’t depend out AMD, Intel’s chipmaking rival. The firm not too long ago introduced Ryzen 6000 Mobile processors, which it’s aggressively marketing at mainstream PCs. Our overview of the new AMD Ryzen 9 6900HS chip confirmed it delivers game-changing efficiency for tiny laptops.
Intel’s new Alder Lake-P chips: mainstream efficiency
Remember, Intel’s Alder Lake-P sequence chips carve out a brand new product designation that hasn’t existed earlier than. Intel classifies the “P” processor as “performance thin and light,” implying that this will likely be its mainstream laptop computer providing. We’re already seeing some enterprise laptops undertake this processor, emphasizing efficiency with out ditching the standard laptop computer chassis for one thing thicker. The P-series chips devour 28 watts.
According to Dan Rogers, Intel’s senior director of cell product advertising, the rationale so as to add a “P”-series processor wasn’t for you, however for PC makers — Intel’s current processors allowed PC makers to push energy consumption and efficiency upward to 28 watts, however they weren’t taking benefit. Carving out the brand new “P” model advised prospects and shoppers alike that they may anticipate increased efficiency, he stated.
Intel’s Alder Lake-P chips will embrace as much as six efficiency cores and eight effectivity cores, with a complete of twenty threads. (This explainer can stroll you thru the distinction between Alder Lake’s new P-Cores and E-cores.) Processor speeds will start at 1.5GHz for the efficiency or P-cores of the Core i3 chips, with as much as 4.4GHz turbo choices. At the excessive finish, efficiency cores speeds will improve from a base clock of 1.8GHz, as much as a most turbo clock velocity of 4.8GHz.
Intel
Intel’s Alder Lake-P sequence chips are designed for “enthusiast” ranges of efficiency, however with out a number of the traits that may outline a very high-end PC powered by Intel’s Alder Lake-H chips, Rogers stated. For instance, Intel’s P-series chips lack the x8 PCI Express connection to the discrete GPU, as a result of they aren’t particularly designed for them. Instead, Intel’s Alder Lake-P features a pair of x4 PCI Express connections to connect with as much as two SSDs. A pair of Thunderbolt 4 ports are supported as effectively, for connections to exterior Thunderbolt docks or exterior shows.
“The vast majority of P-series systems will be running integrated graphics,” Rogers stated. Laptops with discrete GPUs hooked up to P-series components will ship, however will likely be “less common,” Rogers stated.
Instead of discrete GPU help, an Alder Lake P-series pocket book will embrace an analogous built-in Xe graphics core that’s much like Intel’s 11th-gen built-in GPUs: as much as 96EUs, with help for 4 4K shows. As the chart above notes, the variations between the Core i3, i5, and i7 Alder Lake-P processors lengthen to graphics. As the variety of EU cores decreases, you may anticipate the graphics efficiency to lower as effectively.
Intel
The new Alder Lake P-series does enable for a similar number of reminiscence help additionally discovered inside each Intel’s desktop version of Alder Lake and its cell H-series chips: DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. That will enable for some flexibility if it is advisable to improve your laptop computer.
Intel can also be providing an Intel imaging chip, the IMX488, that you could be see in some laptops; Intel additionally refers to this because the Intel IPU 6.0. This in all probability gained’t be highlighted on the record of specs, although Intel is promising you’ll see higher webcam efficiency in consequence. (Intel remains to be recommending a 720p webcam as a part of its premium Evo model, as a result of the scale of the 1080p digicam modules might be too massive to suit inside some laptop computer bezels.) Intel can also be together with a brand new clever audio noise suppression functionality, in order that your roommate vacuuming within the background gained’t break into your Zoom name.
From a efficiency standpoint, Intel is utilizing the argument that it may’t make generation-to-generation comparisons, as there have been no 11th-gen P-series chips to check them to. Instead, Intel supplied two units of benchmarks, one protecting frequent productiveness purposes and the opposite a extra generic gaming roundup. Intel believes that you simply’ll have the ability to play many video games utilizing simply the chip’s built-in graphics, although doubtlessly at decrease settings.

Intel’s U-Series: optimized for low energy
Intel’s Alder Lake U-series chips are provided in considered one of two configurations: both 15 watts or 9 watts. At one time, Intel might need referred to as these “Y”-series chips for ultralight laptops and Windows tablets. In any occasion, Microsoft will virtually actually provide them as choices inside its Surface tablets, although whether or not they’ll reside inside the principle Surface Pro lineup or the smaller, cheaper Surface Go line stays to be seen. The 9W chips are additionally designed for upcoming foldable PCs, although that class has remained a little bit of a white whale to this point. Naturally, lengthy battery life is extra the main focus right here, slightly than efficiency.
Designing the identical processor for 2 various kinds of machines will have an effect on efficiency, although the core counts would be the similar throughout the U-series line: two efficiency cores, and between 4 and eight effectivity cores. If you go for a thicker, extra full-featured laptop computer with an Alder Lake-U sequence chip inside, you’ll be shopping for not less than a Core i3 chip with a base P-core frequency of 1.2GHz, as much as a turbo frequency of 4.8GHz. A U-series Core i7-1265U’s two efficiency cores will run at 1.8GHz at its base frequency and 4.8GHz whereas in turbo mode. The graphics capabilities will likely be about the identical because the P-series chips by way of EU depend, although the clock speeds have been dialed all the way down to preserve energy.
Both the 15W and 9W configurations additionally embrace Pentium and Celeron choices, shrinking down the core counts additional to save lots of value on the expense of efficiency.

The lower-power 9W U-series chips dial down the core clocks dramatically, although the variety of cores stays the identical. Note how the Core i3 base frequency, at 1.0GHz, is decrease than the 15W possibility; the Core i3 turbo clock for the efficiency core remains to be 4.4GHz. At the excessive finish, the bottom P-core clock velocity will increase from 1.1GHz to a turbo velocity of 4.7GHz.
Intel
We don’t have efficiency information for Intel’s new U-series chips…however shoppers in all probability gained’t be shopping for them for efficiency. The key metric, although, will likely be battery life — and we don’t know a lot in regards to the precise numbers there, both.
Intel
That shouldn’t matter, nonetheless. Now that Intel has formally launched each the Alder Lake U- and P-series, we needs to be seeing increasingly more pocket book PCs with them inside, particularly with Intel’s plans to expand its Evo premium notebook brand even additional. (We’re listening to that critiques could start in March.) We’ll have a good suggestion of how they form up earlier than lengthy. Stay tuned to our roundup of the best laptops to see how Intel’s new chips shake out.
