Intel Adds a New Member to the 12th Gen Core Processor Family

Posted on May 10, 2022 by Paul Thurrott in Hardware, Mobile with 13 Comments

Intel announced today that it will further bifurcate the 12th Gen Core mobile processor family with a new HX series of high-end chips.

“With the new core architecture and higher power limits of 12th Gen Intel Core HX processors, we’re enabling content creators to tackle the most demanding work flows like never before,” Intel corporate vice president Chris Walker says. “No more waiting around for processor-intensive workloads to finish, you can stay in the flow. Gamers and content creators will also have access to high bandwidth platform technologies like PCIe Gen 5 with RAID support, and support for ECC memory to ensure high levels of system data integrity and reliability.”

The 12th Gen Core HX “Alder Lake” processors will offer up to 16 processor cores and 24 threads, clock speeds of up to 5 GHz, and will offer 55 watts of base power delivery with up to 157 watts under heavy load. They will deliver up to 80 percent more performance than their previous generation high-end Core chipsets, and that’s before overclocking.

They will also support high-end system components like up to 128 GB of DDR4 or DDR5 RAM and support for ECC RAM and PCIe 5.0. Like other members of the 12th Gen Intel Core lineup, the HX series will offer both Performance and Efficient cores, with the i9 variants offering up to 8 of each core type.

The mobile variants of the 12th Gen Core chipsets now come in four discrete families of processors, U-series, P-series, H-series, and HX-series. The vPro versions of the HX series processors replace the old W-series line.

    Instead of a battery, it comes with a portable generator.

    I’m glad to see Intel innovating and competition is good. But they seem to excel only at extreme power levels, while the market is moving to high performance and efficiency.

      Is the market really moving to performance+efficiency? I mean, that must be true for laptops for the sake of battery life, but when was the last time you saw someone shopping for a desktop and wondering about its power consumption? I don't. If it allows me to get my work done more quickly, I don't care how much power it sucks from the outlet.

        Performance is half the equation. It's the only half Intel can compete with Apple on. A shopper may not go into a store thinking about efficiency and performance until they see what a desktop could look like with a very performant and efficient chip. A powerful desktop the size of an Apple TV or a very sleek and powerful all-in-one. Companies can do more with design if Intel's chips were as equally efficient as they are powerful. Another aspect of this is graphics. What Apple can do with graphics on their chips is far ahead of Intel's integrated graphics. Just look at laptops before and after the first MacBook Air.

        "Is the market really moving to performance+efficiency?"


        Yes, because there is only so far you go with throwing more power at a chip.


        "when was the last time you saw someone shopping for a desktop and wondering about its power consumption? "


        Never, but consumers do buy desktops based on things that are impacted by power draw. Things like how quiet the system are or how large they are will impact buying decisions and power is directly related to those things.

      • bluvg

        I think it depends on the trade-offs and the workload. 1000W PSU vs. 300 for 10% higher peak performance for your workload? Probably not worth it, performance- or cost-wise, especially when computers are often sitting largely idle for most folks.

      • Mark Pfeifer

        Note that this is a mobile chip, so it is meant for portable applications. 55-157 watts is a lot for a portable device.


        As for who looks at power consumption for desktops, I guess I'm weird. When I built my last desktop system, I put a Core i5 CPU in it specifically because I wanted a 65 watt chip instead of a 100+ watt chip. I knew that the system would be running idle or nearly so (I use it in part as a file sever), and I wanted lower idle power usage.

          c't Magazine in Germany does a feature each year about building the "perfect" PC. The question is "perfect" for what?


          They usually make an efficient PC, a cheap office PC and a gaming PC. They get the most questions about the most efficient version and this is the version that is requested to be updated most often.


          They even go into detail about the UEFI settings on the motherboard to get the idle power down under 10W on a Core i5 desktop system.

        Me. I looked for a new desktop based on power consumption and performance.


        I ended up with something more powerful than my old Ryzen 1700 desktop, but using less than a third of the power...


        With power prices rising 40% last year, another 30% already this year and expected to rise again by the end of the year, performance per Watt and right-sizing your PC are the most important factors, when looking for a new PC at the moment. Heck, my Raspberry Pi 400 is looking more tempting as a new desktop replacement with each passing day.

      • TallGuySE

        Yes, the market is moving to performance + efficiently, at least for mobile chips, which this chip is. For example, my MBP lasts all day, runs circles around any other laptop I’ve used, and runs silently. My new Lenovo is often loud, slow, and only lasts a few hours. Guess which one I travel with?

      • Greg Green

        According to PCWorld 80% of the pcs sold are laptops. And without efficiency intel is locked out of the mobile market.


        mobile gaming brings in almost as much revenue as pcs and consoles combined.
