Lenovo Legion 5i Gen 10 (2025) 15"

Manufacturer: Lenovo

The Lenovo Legion 5i Gen 10 (2025) 15″ is a gaming laptop built around a 15.1-inch OLED/AMOLED display running at a 165Hz refresh rate with a 2560 x 1600 resolution and 199 ppi pixel density. Weighing 1,900 g and measuring 21 mm thin, it balances a reasonably portable form factor with the hardware demands typical of modern gaming configurations.

Under the hood, the system is equipped with 32GB of DDR5 memory running at up to 5,600 MHz across a dual-channel configuration, paired with a 1TB NVMe SSD for storage. The discrete GPU is based on the Blackwell architecture, offering 8GB of GDDR7 VRAM, 3,328 shading units, and a floating-point throughput of 9.684 TFLOPS, with support for ray tracing and DLSS. Connectivity includes two USB 3.2 Gen 2 Type-C ports, three USB 3.2 Gen 2 Type-A ports, one HDMI 2.1 output, one RJ45 port, and Wi-Fi 7 support.

  • The display lacks an anti-reflection coating, which may affect visibility in brightly lit environments
  • There is no fingerprint scanner or facial recognition, leaving the device without biometric authentication options
  • The laptop does not include Thunderbolt 3 or Thunderbolt 4 ports, limiting high-bandwidth peripheral and external GPU connectivity
  • No external memory card slot is present, restricting direct media transfer from cameras or other devices
  • A single microphone is included with no Dolby Atmos support, which limits the audio experience for multimedia use
Who is this for?

This laptop is a solid fit for gamers and content creators who prioritize display quality and GPU capability, as the OLED/AMOLED panel at 165Hz delivers smooth, vivid visuals well-suited to gaming and color-sensitive work alike. The Blackwell GPU with ray tracing, DLSS support, and 9.684 TFLOPS of floating-point performance makes it capable of handling demanding titles and GPU-accelerated workloads. Users who rely on multiple screens will also benefit from support for up to four simultaneous displays, and the combination of Wi-Fi 7, five USB 3.2 Gen 2 ports, and HDMI 2.1 ensures a well-rounded connectivity setup for desktop-style workflows.

Who is this NOT for?

Users who need a lightweight, travel-friendly machine will find the 1,900g weight and 21mm thickness less than convenient for daily commuting or frequent travel. The absence of Thunderbolt ports rules it out for professionals who depend on high-bandwidth peripherals or external GPU enclosures. Those working regularly in bright or outdoor environments may also find the display's lack of anti-reflection coating a persistent drawback, and anyone requiring biometric login — whether via fingerprint or facial recognition — will need to rely solely on password-based authentication.

Final Verdict

The Lenovo Legion 5i Gen 10 (2025) 15″ presents a focused gaming and productivity configuration built around a capable Blackwell GPU, a fast NVMe PCIe 5 storage setup, and a 15.1-inch OLED display running at 165Hz — a combination that serves visually demanding tasks and responsive gameplay well. Its connectivity lineup is practical and modern, with Wi-Fi 7, multiple USB 3.2 Gen 2 ports, and multi-display support rounding out a well-equipped package. That said, the chassis weight and the absence of Thunderbolt connectivity mean it is best suited to users with a fixed or semi-fixed setup rather than those seeking maximum portability or high-bandwidth peripheral flexibility. Overall, it is a well-specified machine for gamers and creators who value display quality and GPU throughput within a desktop-replacement form factor.
