At CES this year, Intel officially announced its expanded Alder Lake processor lineup, including the performance-laptop focused H-Series chips, which traditionally fit in the 45-Watt range. For the last several processor generations, Intel has started their roll-outs with the low-power laptop parts, and then expanded the range up to and including desktop processors; but for Alder Lake they have flipped this on its head. Instead, Intel first launched desktop processors, such as the Core i9-12900K, and then moved down the range, with the performance notebook processors coming second, and the low-power processors coming later.

Today, we finally get to take a look at the 12th generation H-Series processors and see how they stack up to not only Intel’s previous 11th generation Tiger Lake platform, but also AMD’s Ryzen 5000 Mobile series. If you’ve not yet taken a look at the initial Alder Lake desktop processor review, definitely check that out since Alder Lake is a big departure from Intel’s traditional CPU design. Featuring a new hybrid CPU design with performance (P-cores) and efficiency cores (E-cores), the new design is more characteristic of what you would see in a smartphone platform, except Intel’s efficiency cores offer almost Skylake levels of performance and should not be disregarded.

Combined with Windows 11, Intel is hoping to improve multi-tasking performance with not only more cores, but also with Windows 11 being able to park jobs that are not in the foreground on the efficiency cores, leaving the performance cores available for the user to avoid system responsiveness problems even when the system is heavily loaded.

The Test System – MSI Raider GE76

Intel is putting its best foot forward, as expected, by supplying the MSI Raider GE76 system for performance testing. This 17-inch desktop-replacement machine is nearly always at the top of all notebook performance comparisons, and for 2022, MSI has kept the chassis the same, save for adding in Alder Lake as well as the latest NVIDIA RTX 3080 Ti Laptop GPU. We recently reviewed the Tiger Lake version of this notebook so if you want to learn more about the device, please check that review out. The Tiger Lake version was the fastest notebook we had ever tested, so expectations are high with the new Alder Lake refresh. We will be covering some of the same aspects here as well.

And for those that follow MSI, be aware that for 2022 they are moving the laptop name ahead of the model number, so it is now the Raider GE76, whereas last year it was the GE76 Raider.

MSI checks all the boxes for 2022. Featuring the Core i9-12900HK, 32 GB of DDR5-4800 memory, the newest NVIDIA RTX 3080 Ti Laptop GPU, and not one but two Samsung PM9A1 1 TB NVMe PCIe 4.0 drives. MSI has improved their cooling solution for 2022 with a new Phase Change thermal pad as well, allowing the system to wick heat away from the hot components into the cooling system with even more efficiency.

The Core i9-12900HK Processor

At the top of the Alder Lake laptop product stack is the Core i9-12900HK processor. It features six of the new Golden Cove P-cores and eight of the new Gracemont E-cores. The P-Core can turbo up to 5 GHz, while the E-Core caps out at 3.8 GHz. The processor has a nominal TDP of 45 Watts – though in the case of our Raider, the TDP appears to be set closer to 75 Watts out of the box – with a peak turbo draw of up to 115 Watts. It offers up to eight lanes of PCIe 4.0 for graphics and two sets of four PCIe 4.0 lanes for storage, along with an additional twelve PCIe 3.0 lanes.

One of the big changes for Alder Lake-H is that Intel has taken a page from the design for their U/Y/P series chips and moved the formerly separate PCH on to the processor package itself. This essentially reduces Alder Lake-H to a single package solution, as like its other mobile brethren, no external silicon is required to provide necessary I/O functionality. By reducing ADL-H to a single package, this will allow for smaller form factor designs, as well as reducing the footprint that needs to be cooled.

The new processor can support up to 64 GB of memory, and supports DDR5-4800, LPDDR5-5200, DDR4-3200, and LPDDR4-4267. There are a plethora of PCIe lanes available with eight PCIe 4.0 lanes for graphics, two sets of four PCIe 4.0 lanes for storage, and an additional twelve PCIe 3.0 lanes. It can't quite match a desktop processor and chipset, and the laptop processors do not have support for PCIe 5.0 yet unlike their desktop counterparts, but it is still a significant amount of expansion available. There is also support for up to four Thunderbolt 4 ports for external I/O.

On the graphics front, the Core i9-12900HK offers Intel Iris Xe graphics with 96 Execution Units on tap with a peak GPU frequency of 1.45 GHz. This is a big step up in terms of integrated graphics from the Tiger Lake H-Series, which only provided 32 Execution Units of Intel UHD graphics. Laptop buyers will be unlikely to find the H-Series where it is not paired with a dedicated graphics card, but it is nice to see that the latest Alder Lake lineup does get access to the top-tier graphics regardless.

    So the ASUS G513QY w/ it's Ryzen 9 5900HX + Radeon 6800M + It's display / Memory don't also impact power consumption?

    That the ASUS that you chose wasn't similar enough?
  • Brett Howse - Tuesday, January 25, 2022 - link

    Of course they do. AMD does way better on battery life but not because of the CPU. That's the point I've been trying to convey.

    AMD's power gating on their GPU is very impressive.

    You said Alder Lake is "max performance with no regards to Fuel/Energy Efficiency" but in both the AMD system and the Intel system, neither CPU is the determining factor for battery life. They are almost irrelevant. Even in a thin and light system with no GPU, the display draws more power than any other component including the CPU.

    I would love an apples to apples comparison but I don't have a Raider GE76 with RTX 3080 Ti and Ryzen 5900HX. Sadly we are constrained by what we have been provided to test, and what manufacturers build.

    5900HX in the G15 isn't running at 45W, that's his whole point, but either you are choosing to ignore it or didn't see it.

    "The ASUS G513QY with the AMD Ryzen 9 5900HX has a similar system, and it also draws around 85 Watts in its maximum performance mode on a 45-Watt processor."

    That's the *same* power as Alderlake-H.
  • undervolted_dc - Wednesday, January 26, 2022 - link

    alder lake it's not at maximum performance mode 85w, it's 115w a good test should account for power and price, a cpu which cost 2x because it's the super top 1% binning for 10% median better perf in benchmarks or that consume 2x for the same should be accounted in each bench results, top performance is a factor but the most important one for laptops are perf/watt/price and for servers is perf/TCO , perf alone is useless ( or useful to reach a certain wanted point from the press.... )
  • Kamen Rider Blade - Tuesday, January 25, 2022 - link

    The specs are similar enough, the only difference is that extra 1.7" display diagonal and extra 16 GB of RAM, but MSI has the more efficient DDR5 instead of older DDR4.

    MSI also has an extra 9.9 Wh to it's advantage.

    Yet the AlderLake laptop was "UnImpressive"
  • jjjag - Wednesday, January 26, 2022 - link

    Brett you are hilarious trying to reason with a fanboi. It's like trying to convince a trumper to get vaxxed because of all the past success we've had with smallpox and polio. For them, it's a religious argument. "Religious" because it ignores all real data and observations, and it just makes them feel better about themselves to hate something. But A+ for trying!

    Funny, I didnt know the black community was full of trumpers. Or the hispanic community, for that matter......
  • Sunrise089 - Wednesday, January 26, 2022 - link

    But Brett, you’re giving the Intel system credit for the GPU+memory+storage. I don’t understand the rationale behind crediting the PCMark scores to Alder Lake but ‘crediting’ the poor battery life to MSI.
