Snapdragon X2 Elite Performance
18 Cores in the Premium 14-Inch Class

The premium thin-and-light market has spent the past year consolidating around 14-inch designs, and that is where the volume of the premium Windows segment now sits. It is also where the design constraints bite hardest. A 14-inch chassis gives an OEM roughly two-thirds of the thermal envelope of a 16-inch flagship and almost none of the room for battery that a larger machine takes for granted, so the silicon inside has to be efficient before it is fast. This report measures three retail 14-inch systems, one per silicon vendor, each representative of what that vendor’s silicon ships in at this tier, to see how the second-generation Snapdragon platform behaves under those constraints.
The Snapdragon X2 Elite X2E-88-100 is the standard 18-core member of the X2 Elite family, built on the new-generation Oryon CPU and paired with the Adreno X2-90 GPU and a Hexagon NPU. It carries the same core count as the X2 Elite Extreme parts we tested in our previous report at lower clocks and in a smaller chassis, which makes it the more relevant part for the segment where most buyers shop. Lenovo ships it in the Slim 7x.
The competition in this class is not the same competition we measured at 16 inches. Intel’s Core Ultra X7 358H is a 16-core Panther Lake part paired with Arc B390 graphics, and the Dell XPS 14 is a serious implementation of it. AMD’s entry is the Ryzen AI 7 445 in the Lenovo Yoga 7a 14, and it is a materially smaller part than the two it is being compared against, with six cores and twelve threads against sixteen and eighteen. That asymmetry shows in the results, so we have flagged it wherever a margin is driven more by core count than
by architecture.
As in our previous Snapdragon family reports, every result here comes from a retail system purchased at market price. Retail hardware reflects the thermal, acoustic, and firmware decisions OEMs made, and it is the only basis on which a value analysis means anything. It also means these are comparisons of implementations as much as comparisons of silicon.

In Best Performance on AC, the Snapdragon system led Geekbench 7 multi-core by 31% over the Intel system and 118% over the AMD system, and single-core by 24% and 36%. On battery, Snapdragon retained 97% of its plugged-in Balanced performance across a six-benchmark set, against 95% for Intel and 74% for AMD.
Battery life benchmarks favored the Snapdragon system in two of three rundowns from an essentially matched 70 Wh pack, with 16.1 hours of local video playback and 11.2 hours of Chrome browsing against 14.4 and 8.6 hours for Intel. Intel won the sustained Procyon Office rundown, 17.4 hours to 14.3 though the Snapdragon-based system performed higher.
At $1,999.99 against $2,749.99 for the Intel system, the Snapdragon system delivered 2.15x the Intel performance per dollar averaged across three representative benchmarks, and 2.6x in AI. The $750 premium is large enough that the Snapdragon system has the best performance-per-dollar in 3DMark, the one test Intel wins on performance.
In a 14-inch chassis the X2 Elite 18-core system we tested leads on CPU, sustained rendering, productivity, AI, and browsing endurance at $750 less than the Panther Lake system, and concedes only integrated graphics and the sustained Office battery rundown. Most margins are wider on battery than plugged in, because the Snapdragon processor retains nearly all of its performance unplugged while the Intel system gives up a little and the AMD system gives up a great deal.
