On paper, Intel’s latest 14th-gen mobile Core HX processors don’t provide pc traders noteworthy in the strategy of an enhance over the earlier generation. In the categorical world, that holds neutral appropriate as properly. And, weirdly, that’s some of the very best news you’ll hear all year when you happen to’re looking out for to glean a gaming pc without breaking the monetary institution, on story of strive in order to glean older thirteenth-gen laptops at a low cost and barely perceive a performance distinction between those and Intel’s latest, biggest CPUs.
And yes, I acknowledged biggest. Intel’s 14th-gen Core i9-14900HX is the fastest mobile PC CPU we’ve ever examined, despite the incontrovertible fact that AMD’s AMD’s Ryzen 8000 Cell family of processors are ready in the wings. Intel’s latest 14th-gen Core HX processors sit alongside its Core Ultra pc chips, despite the incontrovertible fact that the 2 aren’t essentially designed to compete. The Core Ultra (Meteor Lake) chips tend to emphasise lengthy battery life, whereas the Core HX chips level of curiosity on performance first.
And it’s a beast: the unusual Core i9-14900HX delivers 24 cores and 32 threads, combining 8 performance cores and 16 efficiency cores. Nonetheless it’s also largely the same beast as the thirteenth-gen Core i9-13980HX that we examined a year in the past. The assortment of performance (P-cores) cores stays the the same, as does the assortment of efficiency cores (E-cores), plus the entire assortment of threads. Even the technique technology stays the the same, on the Intel 7 node.
Rob into story, the thirteenth-gen Core i9-13980HX used to be a “Raptor Lake” chip. The Core i9-14900HX we examined is a “Raptor Lake Refresh” processor. Intel’s ARK database helpfully compares the 2 chips, which we’ve excerpted below.
The adaptation? Intel boosted the turbo clock hump from 5.6GHz to five.8GHz, because it tweaked the capacity and voltage curve in Raptor Lake Refresh. That played out in assorted ways in our testing.

Intel equipped us with a ugly MSI Raider GE78 notebook with a Core i9-14900HX and an Nvidia GeForce RTX 4090 processor inner. It’s similar to the MSI Titan GT77 we musty for the prior-generation testing of the Core i9-13980HX. (One by one, we’ve also reviewed an Asus ROG Strix Scar 18 with similarly ferocious firepower inner.)
We’re no longer going to level of curiosity on the MSI Raider as a notebook listed here, however order how the 14th-gen HX chip differs from the thirteenth-gen in about a CPU-explicit benchmarks. That will largely dispose of the usage of video games, as a replace specializing in synthetic and precise productiveness assessments that take a look at the CPU’s performance. Forget battery life, too. As a replace, we dialed up the Windows performance slider and the Raider’s cooling to maximum ranges, as we did for the thirteenth-gen MSI Titan GT77.
Put simply, this story is designed to enable you think whether or no longer it be principal to buy a 14th-gen Core HX pc, or settle for an older model as a replace.
14th-gen mobile Core HX performance: extra of the the same
Cinebench R23 is a tried-and-neutral appropriate benchmark, the usage of the entire CPU’s threads to render a scene. Alternatively, it’s also possible to quiz the benchmark to allocate ethical one core to construct the job — to hand when you happen to serene desire video games and apps that are coded to make spend of a single core or thread, in settle on to many.

Here, we perceive an 11 percent enchancment in multi-core performance however ethical a 2 percent enchancment in single-threaded performance. That’s a pretty decent enchancment where the multi-threaded performance is anxious.
Blender is a common, initiate-supply 3D rendering machine musty for keen motion footage. The machine will probably be narrate to make spend of ethical the CPU to render several scenes, as we build here. Nonetheless the advance is itsy-bitsy (2 percent at most) perhaps since the scenes will probably be rendered in a ethical a couple of dozen seconds or so.

It’s a ethical time to point out that CPUs in most cases soar from a heinous energy stage trusty into a turbo energy narrate, most frequently known as PL2. The time at some level of which the processor can dwell in a turbo narrate, is believed as the tau, impacts performance; if the pc can dwell in a turbo narrate for longer, it’ll derive extra work done. Nonetheless the tau is most frequently ethical as dependent on the create of the pc and its cooling machine as noteworthy as the CPU itself, so we can’t read too noteworthy into it. The truth that both notebooks are designed by the the same MSI engineering team, despite the incontrovertible fact that, helps.
We musty a machine known as HWInfo to extract some of this data. In the Core i9-14900HX’s case, the HWInfo machine experiences that the tau must be about 56 seconds, at some level of which this 55-watt CPU sucks 150W of energy and can climb to over 5GHz. After 56 seconds, the chip must lower its hump to a heinous clock hump (2.4GHz, HWInfo experiences) to lead determined of overheating.
That ability that prolonged assessments in most cases push a chip past that tau time. We spend the Handbrake initiate-supply conversion machine to transcode a 4K .MOV file to a H.265 layout and file the time it takes to construct so.
Unfortunately, we came across an error in our thirteenth-gen Core HX testing, so we’re no longer in conjunction with a formal comparison between the 2 gaming notebooks. Nonetheless we did take a look at a thirteenth-gen Core i9-13950HX in a 2d, thinner pc, which generated a ranking of 634 seconds whereas performing the duty. Our 14th-gen Core i9-14900HX notebook conducted the duty in 554 seconds. Over again, the 2 aren’t straight away related, however that’s serene a 10 percent descend.
Unfortunately, that’s where the derive together ends. The V-ray (by Chaos) rendering rush-in on the entire would spend the pc’s GPU, however we can quiz it to make spend of the CPU as a replace. It, too, completes snappily. The 2 pc platforms are if fact be told statistically equal.

So, too, is the Bapco CrossMark benchmark, which makes spend of the CPU to create precise-world tasks. In both V-ray and CrossMark, lower than 1 percent separates the 2 results.

We also in comparison the 2 platforms the usage of the PugetBench take a look at, which is a benchmark constructed by Puget Systems with person assessments in Lightroom, Photoshop, and Premiere Dependable.
PugetBench has moved on to a peculiar “For Creators” benchmark, incidentally. We didn’t procure entry to the older MSI thirteenth-gen pc for testing, or we would procure bustle this benchmark. We centered on the older Photoshop take a look at as a replace. Weirdly, we saw the the same anomaly as we saw in our earlier assessments; performance went backwards by 7 percent.
The PugetBench take a look at does take several minutes to discontinuance, nonetheless, so we also can need anticipated greater performance, a la the Handbrake benchmark, Nonetheless it used to be no longer to be.

Thunderbolt must no longer procure an impact for your resolution
What Intel would similar to you to take into accout whereas evaluating the 14th-gen HX platform, is, properly, the platform: 16 lanes of PCI Teach Gen 5, enhance for DDR5-5600 reminiscence, and so forth. Nonetheless again, that is the entire related to the thirteenth-gen Core HX platform supplies.
There’s one distinction, kind of: Thunderbolt 5. This next-gen I/O recurring will provide 80Gbps (and in some cases, 120Gbps) of bandwidth to displays, GPUs, and other peripherals starting in the 14th generation of Core chips. Nonetheless now not like Thunderbolt 4, Thunderbolt 5 controllers will no longer be built-in in 14th-gen hardware, that implies that pc makers must fabricate it in with a discrete chip. That’s going to require extra fee. Extra to the level, neither Thunderbolt 5 pc controllers nor Thunderbolt 5-licensed peripheral hardware are after all on hand, and acquired’t be unless mid-2024 or later.
Because of the Intel’s reluctance to certify non-Intel platforms as Thunderbolt compliant, AMD Ryzen notebooks spend the properly matched USB4 recurring, as a replace. Nonetheless 80Gbps USB4 hardware isn’t here, both, and acquired’t be unless later this year.
Is the 14th-gen Core HX price the enhance?
If you happen to already maintain a thirteenth-gen Core HX notebook, it is very no longer price upgrading to a 14th-gen Core HX. If you happen to maintain a 12th-gen Core gaming notebook or below, it’s a noteworthy extra compelling option. For that, we’d point out you re-read our older thirteenth-gen Core assessment for performance comparisons to 12th-gen hardware. (Spoiler alert: thirteenth- and 14th-gen Core chips are a large enchancment over their predecessors, in particular in multi-threaded tasks and video games.)
Is the 14th-gen Core HX greater than AMD’s Ryzen 7000 HX series? We are able to’t definitively allege for now. Ditto for Ryzen 8000 Cell, which used to be only nowadays announced. Nonetheless take into accout that the Ryzen 9 8945HS supplies ethical 8 cores and 16 threads, and runs up to five.2GHz at turbo speeds. The Intel 14th-gen Core HX tops that in core depend, threads, and turbo clock hump — so if we procure been to guess, yes, AMD will lunge in the help of.
The truth that the thirteenth-gen Core HX and 14th-gen Core HX are extremely the same is no longer a poke thing, despite the incontrovertible fact that, where you’re concerned. Rob into story, as the unusual 14th-gen gaming notebooks roll out, shops are going to are looking out for to derive rid of their older hardware to make room. And to construct that, they’re going to present the older notebooks at a low cost, as share of a sale.
Nonetheless if a thirteenth-gen Core gaming notebook is almost as ethical as a 14th-gen gaming notebook, that’s a probability. Why buy a 14th-gen Core HX notebook when it’s also possible to buy a thirteenth-gen Core HX pc that’s ethical as awesome at a juicy reduce price?
