Lenovo ThinkPad X1 Carbon wins fastest Wi-Fi speed test
↗
ZDNET’s Lab Award recognizes the business laptop with the highest 5.0 GHz Wi-Fi throughput.
Engineers selecting hardware for latency-sensitive workflows must verify that the ThinkPad X1 Carbon delivers the highest measured 5.0 GHz throughput under the test’s weighted conditions, because raw speed directly impacts data transfer rates and remote collaboration performance.

The Lenovo ThinkPad X1 Carbon achieved the highest weighted average Wi-Fi throughput of 702.36 Mbps in the 5.0 GHz band across all D&I test locations.
The testing methodology used automated iPerf3 scripts, a fixed Netgear Nighthawk RS700S router, and weighted results heavily toward the most challenging D&I Band 3 conditions.
The MacBook Pro M5 ranked last in the 5.0 GHz band despite performing well in 2.4 GHz, highlighting band-specific performance differences that affect network planning.
THE READ
What the cluster adds up to.
The article reports a concrete change: the Lenovo ThinkPad X1 Carbon achieved the highest measured Wi-Fi speed in the 5.0 GHz band among seven tested business laptops, earning a Lab Award and an Editors’ Choice Award.
Adopting this laptop entails a cost consideration beyond price, as its superior throughput may require organizations to allocate budget for higher-end hardware when network performance is a critical requirement.
The testing stops working for other bands and devices; the methodology weights results toward the farthest, most interfered location, which may not reflect typical office deployments that rely on closer proximity or different router models.
The analysis highlights that the test’s weighting and band selection are editorial choices, meaning the reported winner reflects ZDNET’s specific test conditions rather than an universal performance ranking.
Because the experiment used a fixed router and isolated network setup, the results may not generalize to environments with different interference patterns, ISP constraints, or alternative router hardware, limiting direct applicability for engineers designing real-world deployments.
