Intel today is announcing a new range of mobile 12th Gen Core family unit processors designed for enthusiast and desktop-replacement class laptops, the Alder Lake-HX series. Focusing on the more performance-driven loftier-end models, the Alder Lake HX series transfers its hybrid desktop design (ADL-S) into a thinner BGA package with upwards 16 cores (8P+8E) that’s more than suitable for mobile devices. And since it’s based on that desktop hardware, Alder Lake-HX also brings with information technology some boosted features that were previously limited to the desktop, such as back up for PCIe 5.0, as well equally a more desktop-similar base TDP of 55 Watts.
In Jan of this yr, Intel launched its beginning Alder Lake 12th Gen Core mobile processors, the Alder Lake-H family. In February, it then announced more for the lower-powered market through its Alder Lake-P and Alder Lake-U series with up to 14 cores with a mixture of its Functioning (P) and Efficiency (Due east) cores. Intel has now officially launched the more premium of its 12th Gen Core series for mobile, the Alder Lake-HX series with upward to sixteen cores (8P+8E), and its new retention and core overclocking applied science.
The latest in Intel’southward arsenal is designed for premium and enthusiast laptops, with seven new chips ranging from sixteen cores and twenty-four threads, all the way down to an 8-cadre and twelve thread SKU. According to Intel, the Alder Lake-HX series completes its Alder Lake mobile family unit, with options spanning many different markets using its hybrid twelfth Gen Core compages to deliver a pregnant range in mobile performance for enthusiasts, gamers, and workstation use cases.
Alder Lake-HX: Alder Lake-Southward Comes to Laptops
As previously mentioned, the crux of Alder Lake-HX’south design is that Intel is porting their existing desktop Alder Lake-S design to mobile. This is non quite as surprising as it may offset seem, since for years Intel’south H and S serial fries shared identical dies; but since Tiger Lake in 2021, desktop and mobile have become a flake more divorced. On the mobile side of matters, Intel has used a more than laptop-centric design for its high performance mobile fries, incorporating features like Thunderbolt and higher performance Iris Plus/Xe integrated GPUs – and in the almost contempo generation, moving the PCH on-package as well.
The trade-off for this has been that Alder Lake-H shaved off some CPU functionally to accommodate the larger GPU and other laptop features. Which is why the top ADL-H SKUs only offer half-dozen P(erformance) cores, equally opposed to 8 on desktop ADL-South.
Despite this bifurcation of desktop and mobile, it would seem that erstwhile habits die hard, and Intel is bringing its desktop Alder Lake dice and associated platform to the mobile space as Alder Lake-HX. ADL-HX will allow Intel to offering mobile SKUs with 8 P cores, further improving their operation in MT workloads, and shoring up their competitiveness with AMD (whose designs only offer the equivalent of functioning cores). It will as well enable Intel to bring downwards a few of desktop Alder Lake’s more unique features, such as PCIe 5.0 support, memory overclocking, and ADL-S’s extensive I/O connectivity.
But this means that the ADL-HX loses some of the mobile magic of the rest of the mobile Alder Lake family. Integrated Thunderbolt 4 back up is gone, and the integrated Xe-LP GPU goes from a rather capable 96 Eu design downward to a maximum of just 32 EUs, a configuration not suited for much above desktop work. ADL-HX too means the discrete chipset is back, as the design doesn’t contain the on-chip PCH used by Intel’s mobile parts.
The Intel Alder Lake-HX serial also uses a very like packaging size to its existing Alder Lake desktop processors. While the desktop models such as the Core i9-12900K use a socketed LGA package of 45 x 37.5 x 4.4 mm, the Alder Lake HX-series uses BGA packaging with a thinner 45 x 37.5 x ii.0 mm profile to enable information technology to effectively fit in more than space restricting chassis such equally laptops and notebooks. Intel states that this is designed to deliver desktop-like operation in a smaller and more than mobile package. Just this likewise means that ADL-HX can’t pull off the kind of tightly packed, loftier-density laptop designs as the mobile-first chip designs.
All of which raises the question of why Intel is doing this, especially at present, a third of the yr after the launch of their original Alder Lake-H family unit. Ostensibly, it’s for performance reasons, equally Intel’s top SKUs gain 2 more than P cores out of the bargain. So for desktop replacement-class laptops and other high-end devices that aren’t making adept utilise of ADL-H’due south mobile optimizations – such equally past including a detached GPU – they can substantially forgo them for more CPU performance. At the aforementioned fourth dimension it gives Intel a competitive border on AMD, being able to offering more CPU cores (in the course of E cores) besides as existence the first to offering PCIe 5.0 connectivity (even if there isn’t anything to connect information technology to yet).
None the less, there’s no shaking the feeling that after Intel unified its mobile offerings with the Tiger Lake family, Alder Lake-HX is an odd step back (and the odd human out) a generation later. Information technology’southward distinctly a desktop platform downsized for mobile, and despite the name, it has less in common with the mobile-commencement Alder Lake-H than Alder Lake-H itself has in common with the even more mobile Alder Lake-P. In some respects this is i branch of Intel’s mobile offerings catching support with Intel’s desktop offerings, which have gone in the direction of more cores and more than power consumption – albeit at the toll of that branch losing some of its mobile characteristics in the procedure.
Alder Lake-HX Series: 7 New 55W SKUs for Mobile
Looking at the specifications of the seven new Alder Lake-HX series SKUs, it has two new Core i9, iii Core i7, and two Cadre i5 models, each with a base TDP of 55 Westward and a maximum (turbo) TDP of 157 West.
The superlative Alder Lake-HX SKUs are the Core i9-12950HX and the Cadre i9-12900HX chips, with well-nigh identical specifications, including eight operation cores and 8 efficiency cores for a total of 16C/24T. Both accept a base core frequency of ii.iii GHz on the performance (P) cores and ane.7 GHz on the Efficiency (E) cores, with turbo frequencies of v.0 GHz (P cores) and 3.6 GHz (E cores).
Both Core i9 models include 30 MB of L3 cache a 32 Eu iGPU. It’due south likely due to the regression in graphics hardware from the existing 12th Gen Core H-series parts that Intel intends that manufacturers use discrete graphics for the all-time possible gaming and workstation performance.
The simply deviation between both these models is the Core i9-12950HX has the capability for Intel’due south vPro functionality designed for industrial and enterprise apply cases, including official support for ECC retention (which isn’t to be confused with the on-chip ECC on DDR5 retention).

Moving down the stack and Intel has three Core i7 models, the Core i7-12850HX, Core i7-12800HX, and Cadre i7-12650HX. The top two models in the 12th Gen Core i7 HX series include 8 performance and eight efficiency cores, with 20-iv threads (16C/24T), 25 MB of L3 cache, and a 32 EU iGPU.
The Cadre i7-12850HX likewise benefits from Intel’s vPro technologies, including official support for ECC retentivity. Both take similar clock speeds, although the Cadre i7-12800HX has a slightly lower base frequency (100 MHz) on both the P and E cores. Even so, turbo frequencies on the Core i7-12850HX and the Core i7-12800HX are identical at 4.8GHz.
Moving down a notch, the Cadre i7-12650HX drops two P cores, bringing it down to six P cores and eight Eastward cores for a full of fourteen cores. It has the aforementioned base of operations frequencies on both cores as the Core i7-12800HX, simply with a lower turbo frequency of iv.7 GHz (P cores) and 3.iii GHz (Eastward cores), as well as slightly lower levels of L3 cache (23 MB versus 24 MB).
Finally, and perhaps virtually surprisingly, Intel is likewise minting a pair of Cadre i5 HX-Series SKUs, the Core i5-12600HX and the Core i5-12450HX. The Core i5-12600HX supports Intel vPro technologies, including ECC memory support, and it has four performance and eight efficiency cores (12C/16T), xviii MB of L3 cache, and a 32 EU iGPU. Past contrast, the Core i5-12450HX has four performance and just 4 efficiency cores (8C/12T), along with 12 MB of L3 cache, which might not exist optimal for gaming with discrete graphics compared to the other models. And, cementing its status on the bottom of the stack, it has but sixteen EUs for its iGPU, one-third as many as its regular H-serial analogue (12450H).

Lining up the new HX-series parts side-by-side with their existing H-series counterparts, it’due south specially clear that CPU cores and EUs are the only thing differentiating the two parts in terms of performnace. All of the i9/i7 HX parts accept more CPU cores than their H counterpart – typically two more than P cores, though instead the 12650HX ends upwards with an equal number of P cores and 4 more than E cores – at the price of integrated GPUs that offering one-half as much performance (or less). P core turbo clockspeeds are equivalent here, so the actress TDP isn’t unlocking college peak frequencies, and the HX-series parts actually take slowly lower max clockspeeds on the E cores despite the TDP reward.
Meanwhile the i5 parts are the real oddity. The HX-series doesn’t come with any additional CPU cores in these configurations, so outside of a 100MHz more on the P core turbo for the 12600HX, on paper there isn’t any significant advantage to the i5 HX parts. If anything, it’s difficult to argue that the HX parts aren’t a downgrade hither.
Intel Alder Lake-HX: First Mobile Platform with PCIe v.0 and Support for Overclocking
As noted earlier, since Intel is using their disaggregated desktop design here, the Alder Lake HX-serial requires a dissever PCH to provide the rest of it’s I/O functionality. Hither Intel once again uses a PCIe 4.0 10 8 DMI link betwixt the processor and the chipset.
Just at the same time, ane of the fundamental advantages of being derived from Intel’s desktop hardware is that the Alder Lake-HX series is the get-go PCIe Gen v.0-enabled platform for mobile. Each Intel Alder Lake-HX series processor benefits from a total of 48 PCIe lanes, with 16x PCIe 5.0 and 4x PCIe 4.0 lanes hanging off the CPU itself, and another 16x PCIe four.0 and 12x PCIe 3.0 lanes coming from the PCH.
As with the original desktop hardware, the 16x PCIe v.0 lanes are intended for detached graphics, while the CPU’s PCIe four.0 lanes will be used for NVMe-based storage devices.
There is official support for WI-Fi 6E MACs, so vendors can implement upwardly to and including Wi-Fi 6E PHYs of their choice. Vendors can play with upward to and including eight SATA 3.0 and accept support for up to 10x USB3 and up to 14x USB2 ports. Information technology is typically left up to the vendor on how to distribute its USB arrays, as USB three.2 G2x2 and USB 3.two G2 controllers will utilise more bandwidth than regular USB 3.2 G1 ports. Unfortunately, Thunderbolt 4 support is not broiled into this platform; like its desktop counterpart, Thunderbolt is an optional characteristic here. Adding Thunderbolt requires using a discrete controller (up to ii), then it will be left up to laptop vendors to implement their own configurations and designs.
The HX-series also loses Alder Lake-H’s support for low-power retention, such equally LPDDR5 and LPDDR4X. Instead, the new platform is designed to be used with full ability DDR5 and DDR4, officially topping out at DDR5-4800 and DDR4-3200 respectively. Full capacities up to 128 GB are supported, as well every bit official support for ECC memory on the iii vPro-enabled SKUs.
The trade-off for being express to desktop memory is that it comes with some more desktop-like retention features. Specifically, Intel has too lifted the hat on overclocking support for the Alder Lake-HX series, with some new overclocking features designed to clasp out every bit much performance as it can. OEMs can at present include and use XMP retentivity, assuasive for what’s essentially overclocked retention by default. And users can besides do their ain retentivity overclocking, as well.
At that place’southward support for desktop Alder Lake’s Dynamic Retention Boost feature, which allows the memory to be switch between JEDEC or XMP memory speeds based on the load. Within the context of a mobile part, Dynamic Retention Boost allows Intel and its OEMs to offer overclocked RAM without having to pay the full power penalization, by dropping dorsum to more than conservative JEDEC speeds and voltages when the extra performance isn’t needed.
Intel has also unveiled that both the Functioning (P) and Efficiency (E) cores will be independently overclockable from each other. Fittingly, Alder Lake-HX will besides bring with it an updated Intel Speed Optimizer and an enhanced Intel Farthermost Tuning Utility (XTU) designed to provide access to these new overclocking features, equally well as Intel’s usual 1-click overclocking functionality. And all vii of the HX-series SKUs will be able to take advantage of this software and functional, as Intel has confirmed that all of these new chips will officially back up full retentiveness overclocking and at least a limited form of CPU core overclocking – even the vPro-capable SKUs.
What remains a flake murkier in light of these overclocking features is how much is however under warranty. On the desktop, Intel straight sells chips to consumers; on mobile, this is non the case. Then while Intel typically voids the warranty on whatsoever desktop parts that are overclocked, for mobile devices this is an all-OEM situation. So whether overclocking is covered under warranty will sit with the laptop vendor itself, such equally ASUS. Not every laptop vendor is as friendly with overclocking as the rest, so this is something that should exist checked before purchase.
New Intel Alder Lake-HX Laptops for Gaming and Workstations: Many to exist Appear
As does happen when a new series of mobile processors get announced, along with it comes a plethora of new laptop announcements. While nosotros expect at that place to be many to be appear over the coming days and weeks from vendors such as Lenovo, HP, ASUS, Dell, MSI, and GIGABYTE, Intel has already provided model numbers on a few expected launches to supplement its own launch of the Alder Lake-HX series.
While nosotros don’t take official or any technical specifications for the new models (at the time of writing), we know that ASUS intends to launch a ROG Strix Scar 17 SE model with Intel’due south Alder Lake-HX processors, as well as the Lenovo Legion 7i, an MSI GT77 Titan, GIGABYTE Aorus 17X and 15X models. every bit well as a couple of models from Dell, the Precision 7770 and 7670.
As we’ve mentioned, we await to see many more laptops announced featuring Intel’s Alder Lake-HX serial processors for mobile, so keep your optics peeled over the side by side couple of weeks for more details on these.
