Intel’s Alder Lake H-series laptop chips take on Apple M1 Max with vengeance

Intel is expanding its 12th-gen Alder Lake platform to mobile. The company announced eight new mobile chips being shown off in laptops at CES 2022, as well as a swath of low-power mobile processors arriving within the first few months of the year.

The chips in question come from the 45-watt H-series. These enthusiast chips have the highest power budget out of any of Intel’s mobile options, making them ideal for gaming laptops like the Alienware X14 and creator devices from Asus, Acer, Lenovo, HP, and more.

Over the next few months, many of the best laptops and gaming laptops will be updated with these new chips. You can find the specs of the H-series chips in the table below.


Cores Max boost frequency Intel Smart Cache (L3) Base power
Core i9-12900HK 14 (6P + 8E) 5.0GHz 24MB 45W
Core i9-12900H 14 (6P + 8E) 5.0GHz 24MB 45W
Core i7-12800H 14 (6P + 8E) 4.8GHz 24MB 45W
Core i7-12700H 14 (6P + 8E) 4.7GHz 24MB 45W
Core i7-12650H 10 (6P + 4E) 4.7GHz 24MB 45W
Core i5-12600H 12 (4P + 8E) 4.5GHz 18MB 45W
Core i5-12500H 12 (4P + 8E) 4.5GHz 18MB 45W
Core i5-12450H 8 (4P + 4E) 4.4GHz 12MB 45W

The flagship Core i9-12900HK tops out at 14 cores, split across six performant (P) cores and eight efficient (E) cores. Intel says the new chip delivers up to a 28% improvement in games over last-gen’s Core i911980HK, as well as an even larger improvement over AMD’s competing Ryzen 9 5900HX.

Most interesting is the comparison to Apple’s M1 Max, which shows up in Apple’s 2021 MacBook Pro. Intel says the Core i9-12900HK can outclass Apple’s best in Premiere Pro, Lightroom Classic, and Blender, among other apps. Early leaked benchmarks showed the chip performing as much as 50% better than the M1 Max. Some leaked benchmarks even show the cheaper Core i7-12800H beating Apple’s chip.

Intel only shared details about its H-series processors, but P-series (28W) and U-series (15W and 9W) chips should arrive within the first few months of 2022. We don’t have detailed specs on these chips yet, but we’ve already seen them in action in machines like the Dell XPS 13 Plus. In fact, there is a range of laptops using these chips being shown at CES 2022, suggesting that they’ll roll out sooner rather than later.

The new chips use the same hybrid architecture as the rest of the Alder Lake range, combining P-cores and E-cores to boost multithreaded performance. In addition, the mobile chips come with Wi-Fi 6E, Thunderbolt 4 support, and platform technologies like Intel Deep Link. They also support four memory standards: DDR5, DDR4, LPDDR5, and LPDDR4.

Intel says over 100 designs are already confirmed, many of which are being shown off at CES 2022. These include new HP Elitebook models, as well as a range of new Blade laptops from Razer. Unlike Intel’s newly announced 12th-gen desktop processors, all of the H-series chips come with Alder Lake’s signature hybrid architecture.

Intel 12th-gen Alder Lake CPUs: Everything you need to know
Intel Core i9-12900K box on a desk.

After talking up Alder Lake for more than a year, Intel has released all of the CPUs in its 12th-generation range. This new generation brings the same slew of performance improvements worthy of our roundup of the best processors but also marks the first time Intel has used its 10nm manufacturing process on desktop and the first slot-in CPUs with a hybrid architecture.

There's a lot to talk about with Alder Lake. We rounded up everything you need to know about 12th-gen Alder Lake processors, including how much they cost, what kind of performance you can expect, and how they work with new Z690 motherboards.

Leak reveals Intel’s new Alder Lake-HX chips with 16 cores
A Core i9-12900KS processor sits on its box.

Intel has a new set of laptop CPUs coming out. Though the processors haven't been officially announced, Chinese news outlet ITHome has uncovered the specifications for the new chips.

The new processors will be beefed-up versions of Intel's regular mobile Alder Lake lineup, with up to 16 cores and 24 threads. The new mobile processors (called Alder Lake-HX), are meant to compete with AMD's new Ryzen 6000 processors. Intel's chips will have up to twice as many cores, but we will have to see how their individual performance actually holds up.
