Earlier this month, Intel introduced Alder Lake HX, a brand new sequence of Twelfth-generation cellular processors. Properly—not strictly cellular. These new work-focused laptop computer CPUs are primarily based on the corporate’s desktop Alder Lake chips, however in a BGA bundle. (That’s, it’s soldered onto the motherboard, quite than being in an ordinary socketed LGA bundle which you can swap out like in a desktop PC.)
As you would possibly guess, these new Twelfth-gen Core HX chips are a lot beefier than their commonplace H-class siblings present in typical gaming laptops. Alder Lake HX are 55W chips with a max turbo energy ranking of 157W, whereas Alder Lake H are 45W with 115W max turbo energy.
However what does that truly imply if you’re utilizing a laptop computer with an HX CPU as an alternative of an H processor? Once we acquired the prospect to have a preview take a look at the brand new MSI GT77 Titan, we determined to place its Core i7-12800HX to the check and discover out. Spoiler alert: It’s an absolute massacre in a number of eventualities, although the HX can’t declare a clear sweep throughout the board. In the correct eventualities, nonetheless, this desktop-based chip demolishes the competitors.
The check laptops
Our explicit MSI GT77 configuration bundled its Core i7-12800HX with an Nvidia GeForce RTX 3070 Ti and 32GB DDR5/4800 reminiscence. Like different high-end Alder Lake CPUs, the HX sequence options Intel’s new hybrid structure, packing each efficiency and effectivity cores. (Sorry, no all-performance-core chips.) The 12800HX options 8P/8E cores and 24 whole threads (e-cores lack hyperthreading), with a max turbo clock pace of 4.8GHz on the efficiency cores and three.40GHz on the effectivity cores. It’s not the highest of the stack—that distinction belongs to the Core i9-12950HX—but it surely nonetheless can ship fairly a punch.
Intel
Going up towards this beastly processor have been two different Intel cellular CPUs and one from AMD, too. An MSI GE76 Raider with Intel’s flagship Core i9-12900HK (6P/8E cores, 20 threads), an Nvidia GeForce RTX 3080 Ti, and 32GB DDR5/4800 reminiscence served because the tribute for Alder Lake H. The 12900HK boasts a max turbo pace of 5.0GHz on the efficiency cores and three.8GHz on the effectivity cores. In the meantime, an older MSI GE76 Raider with an Eleventh-gen Core i9-11980HK, RTX 3080, and 32GB DDR4/3200 reminiscence was introduced out from mothballs to symbolize last-gen Tiger Lake H CPUs. Its chip sports activities 8 cores and 16 threads, with a max turbo pace of 5GHz.
As for our AMD consultant, an Asus ROG Strix Scar G17 and its Ryzen 9 5900HX, RTX 3080, and 32GB DDR4/3200 reminiscence was added to the combination. This chip is from AMD’s 2021 cellular processor launch—the 6900HX is probably the most present providing from AMD, however sadly, the 5900HX is all we had readily available. The 5900HX has 8 cores and 16 threads, with a most increase clock of 4.6GHz.
The lowdown
Getting a real apples-to-apples comparability between laptops is tough, particularly when evaluating processors from completely different lessons. A laptop computer’s measurement and particular design affect efficiency, so you possibly can’t make onerous and quick statements primarily based on benchmarks as when evaluating desktop CPUs.
Nonetheless, the numbers may give you a normal concept of what to anticipate, even on this preview take a look at the HX sequence. Listed here are 4 fast takeaways to satiate your curiosity about Alder Lake HX.
(For a deeper dive into these outcomes, try the embedded YouTube video beneath—my colleague Gordon Mah Ung discusses the MSI GT77 and his benchmark findings intimately.)
1) Mighty efficiency in multithreaded duties
Intel HX processors are clearly for if you want desktop PC energy in a laptop computer physique. The Core i7-12800HX tore by encoding, rendering, and different closely multithreaded duties at a tempo that different laptop computer chips couldn’t sustain with.

In Maxon’s Cinebench R23 rendering benchmark, the Core i7-12800HX simply nabbed the highest spot. It outperformed the runner-up, the Core i9-12900HK, by 32.23 %. It additionally crushed the last-gen Core i9-11980HK and Ryzen 9 5900HX by 68.45 and 54.61 %, respectively. The story’s comparable in our Handbrake encoding check, through which we’ve got this system crunch down Blender.org’s Tears of Metal 4K video right into a smaller HEVC H.265 format. The 12800HX finishes the duty about 30 % quicker than the 12900HK, 41 % quicker than the 5900HX, and 63 % quicker than the 11980HK (oof).

The outcomes are much more stark in V-Ray 5, one other rendering benchmark. Right here the 12800HX stomps all around the laptop computer processors. The development over the 12900HK is a whopping 98.21 %, and it posts triple-digit proportion uplifts over the 11980HK and 5900HX.
2) A CPU alone can’t win all battles
Gordon Mah Ung/PCWorld
The Core i7-12800HX doesn’t dominate in every thing. A take a look at the outcomes from Pugetbench’s Premiere Professional benchmark present this final result—and extra particularly, how uncooked CPU firepower can’t at all times win each spherical. In Premiere Professional, which makes use of each the CPU and GPU, the Core i9-12900HK and its quicker RTX 3080 Ti took the highest spot.
No surprises right here, but it surely’s a great reminder {that a} laptop computer’s graphics can affect efficiency outcomes. Furthermore, how a lot a discrete GPU can stretch its legs in a selected laptop computer makes a distinction too. For instance, the 12800HX’s paired RTX 3070 Ti has a decently hefty 150W TGP, however the Ryzen 9 5900HX’s RTX 3080 will get capped at simply 130W TGP. That design has actual world repercussions, with that Asus Scar 17 sitting firmly on the backside of the heap.
By the way, we selected to run this benchmark with the discrete graphics enabled to be extra true to life. You’ll by no means discover these CPUs in a configuration missing a devoted GPU. Nevertheless, if you happen to’re curious, switching off the discrete graphics wouldn’t have made for a good enjoying floor. The 12900HK’s built-in graphics pack 96 execution items (EU), whereas the 12800HX sports activities simply 32.
3) Dimension could make up for would possibly
Throughout the HX sequence announcement, Intel mentioned the Core i9-12900HK would stay the highest gaming CPU—however the HX chips would nonetheless be “nice gaming processors as effectively.” Preliminary check outcomes bear that out, even given the disparity in our check laptops’ specs. The 12800HX and its RTX 3070 Ti dipped beneath the 12900HK and its RTX 3080 Ti by solely a handful of frames per second in two of our three gaming benchmarks, and it even took the lead in Counter-Strike: International Offensive by about 5 %. CS: GO tends to lean extra on the CPU, which is probably going how the 12800HK beneficial properties a bonus.

That mentioned, recall what we mentioned earlier about laptop computer measurement and design. We are able to make certain that this 12800HX + RTX 3070 Ti laptop computer solely barely underperforms the MSI GE76’s 12900HK + RTX 3080 Ti, however for different laptops with comparable configurations, you might not see the very same final result. The MSI GT77 Titan is a large seven-pound laptop computer, whereas the MSI GE76 Raider is smaller at 6.4 kilos. Put the GE76’s parts into a bigger pocket book and you would see a wider efficiency hole. And it stays to be seen what an apples-to-apples 12900HX vs a 12900HK showdown will appear like.
4) Laptop computer housing, desktop energy consumption
Gordon Mah Ung/PCWorld
Those that are accustomed to processors already knew that the Core i7-12800HX was going to guzzle extra electrical energy than the true laptop computer CPUs. Once we measured energy consumption throughout Cinebench R23’s default check, which takes 10 minutes to finish, the Core i9-12900HK hovered roughly between 120W and 130W for many of the benchmark. The 12800HX frolicked nearer to 180W, however with larger drops after ending a body in comparison with the 12900HK.
What’s fascinating right here is seeing affirmation that 12800HX falls consistent with what we normally see from extra power-efficient desktop processors. (We don’t presently have this actual knowledge for Alder Lake chips, however you possibly can have a peek at our latest Ryzen retrospective knowledge.) And naturally, with extra energy comes quicker and better efficiency—16 frames rendered vs the 12900HK’s 13, and in much less time.
Remaining ideas
Even with out realizing what additional {hardware} and software program tuning might enhance, this efficiency preview makes it clear that the Core i7-12800HX is a ferociously spectacular CPU. Squishing a desktop Alder Lake processor right into a laptop computer offers fairly a lift to hurry. Content material creators and different customers who want workstation-level efficiency ought to love what’s on provide right here.
That doesn’t essentially make the HX sequence of chips the best for everybody, although. As enjoyable as high-powered {hardware} is, the completely different lessons of processors exist for a motive. In case your main want revolves round portability, a featherlight PC with an Intel or AMD U-class processor (just like the lately launched Ryzen 9 6800U) is the correct selection. Identical for players—until you’re additionally usually creating movies primarily based in your gameplay, you possibly can nonetheless get loads of enjoyment out of a laptop computer with an ordinary H-series processor. What issues extra is the highest performers in that class, in addition to the efficiency of the particular laptops you’re contemplating.
No matter what you most want out of a laptop computer, the most recent releases make selecting a brand new PC each simpler and more durable. Competitors is presently so fierce between Intel and AMD that every new technology gives materials advantages. Anybody attempting to resolve between future-proofing their buy and saving cash by going with the earlier gen faces a tricky name. On the identical time, CPUs that stink are much more uncommon. It’s a great downside, all issues thought of.
For those who’re questioning which particular pocket book is one of the best to your private wants, you’ll want to try our roundup of one of the best laptops. It’s loaded with concrete suggestions culled from dozens upon dozens of latest critiques, with picks for each want and finances.
