The vast majority of ultraportable laptops available in the last years have been built on Intel Core U hardware-platforms, with options for dual-core processors with or without HyperThreading.
And while the Kaby Lake hardware generation provides solid performance for everyday tasks like browsing and editing texts and watching movies, especially when paired with the right amount of RAM and the fast SSDs available these days, there’s still only that much a dual-core CPU can do in terms of multitasking and intense multi-core loads.
This changes as of Q3 2017 with the introduction of the Intel KabyLake-R (Refresh) line which includes Intel’s first low-voltage quad-core processors. These are part of Intel’s 8th generation of chips, thus their denomination gets an 8 after the dash, but they are in fact a revised version of the Kaby Lake architecture and not the Coffee Lake or the Cannon Lake platforms, which are scheduled for the future (2018) and we’ll address in different articles when available.
We’re not going to get in depth on the performance of these quad-core Core U notebook-processors in this post, will save that for other articles (here’s the one that covers the Core i5-8250U, with more updates to come). We will however mention below the CPUs that are part of the Intel KabyLake-R 8th gen series and their particularities, and then jump to the main topic of the article, the list of Core U quad-core ultraportable laptops you will be able to find in stores in the months to come.
First of all, these are the Core U Kaby Lake-R processors available at the time of this post (to be updated)”
- Core i5-8250U – 1.6 GHz base clock with up to 3.4 GHz Turbo, HyperThreading, 6MB L3 cache – $297;
- Core i5-8350U – 1.7 GHz base clock with up to 3.6 GHz Turbo, HyperThreading, 6MB L3 cache – $297;
- Core i7-8550U – 1.8 GHz base clock with up to 4 GHz Turbo, HyperThreading, 8MB L3 cache – $409;
- Core i7-8650U – 1.9 GHz base clock with up to 4.2 GHz Turbo, HyperThreading, 8MB L3 cache – $409.
They share a few common traits, like the 15 W TDP, 14 nm lithography, support for up to 32 GB of DDR4 memory and the Intel UHD 620 graphics chip integrated within the die. The increased number of cores is the strong selling point here, while the graphics inside is similar to the HD 620 solution on the standard KabyLake dual-core options, just capable of running a little faster.
You will however notice that the base clocks of these quad-core CPUs are much lower than those of the existing dual-core Kaby Lake processors, but that’s compensated by the high Turbo speeds, so performance per core is pretty much on par with the Core i5-7200U or i7-7500U, which means multi-core performance gets a major boost with these new lines. We already spent some time with laptops built on this platform and can confirm the fact that the quad-cores show 30 to 60% gains in benchmarks and certain demanding loads, and you’ll find more details in our reviews.
Price wise the quad-core 8th generation KabyLake-R CPUs are only marginally more expensive than the 7th gen KabyLake dual-cores ($281 for i5-7200U vs $297 for i5-8250U; $393 for i7-7500U vs $403 for i7-8550U), so the newer configurations won’t cost an arm and a leg. There are however two important questions that remain to be answered in future reviews, and that’s how will these quad-cores perform thermally and acoustically in thin-and-light laptops that were already running pretty hot with dual-core builds, as well as whether they’ll be able to consistently maintain their high Turbo Speeds in continuous loads. Stay around for details in our future tests.
Knowing all these about the 8th gen KabyLake-R platform, let’s jump to the actual list of laptops built on these quad-core ULVs, available below. Details are still scarce for now, but the list is a continuous work in progress and we’re constantly updating it. If you spot anything that’s not in here and should be, please tell us about it in the comments section at the end.
The selection is split in two sections, one of the ultraportable options with 14-inch or smaller screens, and another of full-size 15-inch or larger laptops.

- tablet + folio: stand-alone tablet paired with matching keyboad-folio;
- slider: 2-in-1 laptop whose screen slides up and down on top of the body and reveals a keyboard hidden underneath.
- Resolutions: HD ( 1366 x 768 px), WXGA+ (1440 x 900 px), HD+ (1600 x 900 px), FHD (1920 x 1080 px), WUXGA (1920 x 1200 px) FHD+ (2160 x 1440 px), retina (2304 x 1440 px), QHD (2560 x 1440 px), WQXGA (2560 x 1600 px), QHD+ (3200 x 1800 px), UHD (3840 x 2160 px) – also see this post;
That’s about it for now with this list of Intel 8th gen laptops, but like I said earlier, we’re constantly updating this list and adding new ultraportble laptops built on Intel KabyLake-R / Coffee Lake quad-core Core U processors. The comments section below is also open for any suggestions and questions, and we’re around to help out if we can.
