As of mid 2018 you can buy performance laptops with an Intel Core i9 processor, namely the Core i9-8950HK, part of the Intel Coffee Lake platform.
In this article we’ll tell you what to expect from the mobile Core i9 CPU, how it compares to the mainstream Core i7s available in most multimedia and gaming notebooks these days, and whether (or rather when) this processor is worth your money, considering you’ll have to pay a significant premium for it.
This aside, we’ve also compiled a complete list of the notebooks motorized by Core i9 processors that are available in stores, and we’ll updated it in the months to come with new SKUs as they’re announced.
Of course, it comes to no surprise that most of these computers are hefty full-size desktop replacements, but there are also a few portable options to consider. Just make sure to read proper reviews before taking the plunge on any of those, so you’ll find out if their cooling implementations are actually capable of keeping the i9 at bay. If not, it would make much more sense to just go with the more affordable i7 configurations.
The Core i9-8950HK mobile processor
The i9-8950HK is the top-tier CPU in Intel’s Coffee Lake H line of performance processors for mobile computers. It gets 6 cores, 12 threads, 12 MB of cache memory, a standard frequency of 2.9 GHz and a maximum Turbo Boost frequency of 4.8 GHz (we’ll get to that in a bit), and supports up to 64 GB of DDR4 2666 MHz of dual-channel RAM.
The K at the end of the name means this processor gets an unlocked multiplier and is thus, overclockable, which means that if the cooling implementation allows, it can run at higher than stock speeds.
The table below shows how it compares to the mainstream Coffee Lake i7-8750H, as well as the Kaby Lake i7-7820K that it supposedly succeeds.
|i9-8950HK (Ark)||i7-8750H (Ark)||i7-7820HK (Ark)|
|Litography||14++ nm||14++ nm||14+ nm|
|CPU Base Frequency||2.9 GHz||2.8 GHz||2.9 GHz|
|Turbo – All Cores||–||3.9 GHz||3.5 GHz|
|Turbo – 1 Core||4.8* GHz||4.1 GHz||3.9 GHz|
|L3 Cache||12 MB||9 MB||8 MB|
|Memory||DDR4 – 2666 Mhz||DDR4 – 2666 Mhz||DDR4 – 2400 Mhz|
Aside for the increased amount of cache compared to the i7s, the i9 also gets Thermal Velocity Boost (TVB), which in Intel’s words “opportunistically and automatically increases clock frequency up to 200 MHz if the processor temperature is low enough and turbo power budget is available”. Hence the 4.8 GHz maximum Turbo Boost (*).
According to Intel’s slides though, the “low enough temperature” is of only 50 C, which means the i9 most likely would only clock to 4.6 GHz sporadically and for very short bursts at the beginning of complex loads, otherwise maxing out at 4.6 GHz. Even so, that’s higher than the 6-core i7-8750H can reach, and as long as the implementation keeps temperatures and throttling at bay, we can expect the i9-8950HK to offer a significant boost in performance over the more mainstream option, even without overclocking.
Speaking of performance, Intel advertises the i9-8950HK in comparison to the older i7-7820HK, claiming up to 29% better overall performance, as you can see in the picture below.
I find it far more more interesting how the i9-8950HK fares against the i7-8750H though, but the performance greatly varies base on each SKU, as it’s highly dependent on the cooling implementation.
Still, the table below gives you a ballpark idea of what to expect (the results are based on our tests of the 8750H and these scores of the 8950HK).

Portable Core i9 laptops
This section includes a list of the portable notebooks that can be configured with a Core i9-8950HK processor. Given the compact footprints and slim profiles of these computers, as well as our experience with some of them in past, I wouldn’t expect to get as much as possible from the i9 on these, so make sure to read reviews in order to figure out if the i9 models are actually worth getting, or you’d better stick to the i7s.

Full-size Core i9 notebooks
This section includes the full-size Core i9 notebooks.
Expect most of these to be hefty and heavy, with very few exceptions, but at the same time they should squeeze the most out of the hardware inside and allow for tweaking and overclocking. At the same time most of these laptops are extremely noisy with gaming, to the point you’ll need headphones for comfortable use, which is somewhat understandable on the few thinner models, but hard to accept on the chunkier ones.
