A [Signal65 comparison](https://signal65.com/research/snapdragon-x2-elite-performance/) published October 1 puts the 18-core Snapdragon X2 Elite in a retail Lenovo Slim 7x against an Intel-powered Dell XPS 14 and an AMD-powered Lenovo Yoga 7a 14. The Snapdragon laptop led several CPU and on-device AI tests, but Intel won the graphics test and a sustained Office battery rundown. **Qualcomm commissioned the research**, which Signal65 conducted using laptops it says it bought at retail. The results describe those three machines under the reported settings; BIG CHANGE did not test them.

## The big change

- **What changed:** Signal65 has moved its X2 comparison into 14-inch retail laptops with the standard 18-core Elite chip. The report gives buyers results from complete shipping systems across plugged-in, unplugged and battery-life tests.
- **Why it matters:** A laptop buyer can see different strengths within the same test set: the Snapdragon Lenovo leads selected CPU and AI workloads, while the Intel Dell is faster in the tested graphics workload and lasts longer in sustained Office use. The useful choice depends on the task and the complete machine.
- **What to watch:** Equivalent tests in other laptops using these chips would show how much of each margin survives different cooling, power settings, displays and software builds. Signal65 tested one retail implementation per processor.

## Three retail laptops, three different configurations

The [paper by Ryan Shrout, Signal65's president and general manager, and Ken Addison, its client performance director](https://signal65.com/wp-content/uploads/2026/09/Signal65-Lab-Insight_Snapdragon-X2-Elite-18-Core.pdf) is dated September 2026; Signal65 posted it October 1. It says benchmark runs and system details were captured July 31. Its test group was a Lenovo Slim 7x (83QR) with Snapdragon X2 Elite X2E-88-100, a Dell XPS 14 (DA14260) with Intel Core Ultra X7 358H, and a Lenovo Yoga 7a 14 (83TD) with AMD Ryzen AI 7 445.

The batteries were close in design capacity: 70 Wh in both Lenovos and 68.6 Wh in the Dell. Other differences matter. The Snapdragon and Intel machines had 32 GB of memory; the AMD machine had 24 GB. The Snapdragon laptop ran Windows 26H1, while both x86 laptops ran 25H2. The processors have 18, 16 and six CPU cores respectively. Signal65 itself warns that the large multi-core margin against AMD partly reflects that core-count gap. Each manufacturer's cooling, firmware and power tuning also travels with its laptop.

These differences are especially relevant to battery life and a price comparison. The report lists retail prices as purchased, from $1,549.99 for the AMD Lenovo to $1,999.99 for the Snapdragon Lenovo and $2,749.99 for the Dell. It does not compare otherwise identical chassis or current sale prices. [Windows Central's contemporary discussion](https://www.windowscentral.com/hardware/qualcomm/qualcomms-snapdragon-x2-doesnt-need-the-extreme-badge-to-beat-intel-signal65-study) also notes different displays in the Snapdragon and Dell laptops, another reason to read runtime as a whole-device result.

## CPU and AI results favor the tested Snapdragon Lenovo

In Signal65's plugged-in Best Performance mode, Geekbench 7 multi-core scores were 24,016 for the Snapdragon system, 18,360 for Intel and 11,008 for AMD. The corresponding single-core scores were 3,237, 2,602 and 2,384. Cinebench 2026 multi-thread rendering put Snapdragon at 5,240, Intel at 3,538 and AMD at 2,479. These are reported run averages from the retail laptops.

The Office result is closer in the default Balanced power mode. UL Procyon Office scored the Snapdragon Lenovo at 7,654 and the Intel Dell at 7,488, a 2% gap in Signal65's table. On battery in Balanced mode, the reported overall Office scores were 6,606 and 5,968. Across six selected benchmarks, the Snapdragon laptop retained an average 97% of its plugged-in Balanced-mode score on battery, against 95% for Intel and 74% for AMD. Its Office score alone retained 86%.

For on-device AI, the paper reports 4,360 for Snapdragon and 2,302 for Intel in UL Procyon AI Computer Vision at plugged-in Best Performance. In the newer AI Computer Vision 2.0 WinML path, the scores were 2,160 and 1,645, a smaller 31% lead. The second result uses the Windows ML runtime; both results concern this benchmark's vision inference workloads. They do not establish performance across text generation, every Windows AI feature or output quality. Signal65 says it collected Geekbench AI results but excluded them because execution-backend coverage was not uniform among the systems.

## Battery and graphics divide the result

All three battery rundowns used Best Power Efficiency mode. The Snapdragon Lenovo lasted 16.1 hours in local 1080p video playback and 11.2 hours in Signal65's Chrome browsing rundown; the Intel Dell lasted 14.4 and 8.6 hours. Sustained Procyon Office reversed the order: 14.3 hours for Snapdragon and 17.4 for Intel. Signal65 also reports a higher Office performance score for Snapdragon during that rundown, so the time result and the amount of work per unit time answer different questions. Display, firmware and software differences remain part of each measured outcome.

Intel also led the tested integrated-graphics workload. In 3DMark Steel Nomad Light at plugged-in Best Performance, the Dell scored 6,320 in DirectX 12 versus 4,879 for the Snapdragon Lenovo. The Snapdragon score was 23% lower. Under Balanced mode, that shortfall narrowed to 12%. The paper's Chrome tests were mixed too: Intel won WebXPRT 5 plugged in and several browser benchmarks on battery. Those exceptions matter when using the CPU and AI figures to choose an entire laptop.

Signal65 calculates that the Snapdragon configuration delivered more performance per dollar across three selected CPU, rendering and AI measures at its purchase price. That calculation reflects the three tested configurations and their purchase prices. Other retail designs need their own comparisons: the report cannot establish whether its margins persist with different cooling, displays and power settings.
