Related Benchmark Evidence
The embedded dataset is for a related configuration. CPU, RAM, display, weight, and battery differ. Use it only to inspect the cited RTX 5070 115W test rows; it does not establish performance for the linked OLED retail offer.
Thermals and Acoustics
No matching thermal or acoustic dataset is published here. Measurements from the related configuration are not transferred to the OLED model because CPU, chassis configuration, display, memory, and test conditions differ.
Display & Build
The linked Lenovo Legion 5i uses a 15.1-inch 2560×1600 OLED panel at 165Hz. Legion 5i Gen 10 listings can use different processors, displays, memory, and storage, so verify those specifications before purchase.
RAM and SSD Upgrade Guide
The reviewed configuration already has 32GB DDR5-5600 and a 1TB NVMe SSD. Lenovo's platform specification lists two dual-channel DDR5 SO-DIMM slots supporting DDR5-4800/5600, with current Lenovo offerings up to 32GB. The phrase "up to 32GB offering" describes Lenovo's tested retail configurations; this page does not turn it into an unsupported claim that larger third-party kits are guaranteed.
| Component | Verified platform path | Practical recommendation |
|---|---|---|
| Memory | 2x DDR5 SO-DIMM slots; DDR5-4800/5600; up to 32GB Lenovo offering | Keep the factory 32GB for gaming. Consider more only when a memory vendor qualifies the exact model and your workload demonstrably exceeds 32GB. |
| Storage | Two M.2 2280 PCIe 4.0 x4 slots; platform supports two drives | Add a second PCIe 4.0 M.2 SSD for more game storage. Verify which slot the factory drive occupies and retain the mounting hardware and thermal pad. |
Use the DDR5 SO-DIMM buying guide before selecting memory, verify the platform in Lenovo's official specification, and confirm replacement parts with Kingston's Legion 5 configurator.
The 32GB SO-DIMM link is for upgrading a 16GB configuration or replacing its memory as a matched 2x16GB kit. The linked Lenovo Legion 5i already has 32GB, matching the offering documented in Lenovo’s platform specification, so storage remains its sensible first upgrade. The linked SSD is the bare M.2 2280 model without a tall desktop heatsink.
OLED for Work and Games
Lenovo's platform specification distinguishes typical SDR brightness from peak HDR brightness. They describe different operating conditions; the larger HDR number should not be used as the screen's normal desktop brightness. The listed glossy surface is also relevant if you work beside a window or under overhead lights.
For gaming, start with your preferred image quality at 2560×1600, then compare a suitable upscaling mode if performance is insufficient. Do not assume a 165Hz panel means every game will render 165 frames per second. For editing, verify the color profile and application workflow rather than treating a gamut specification as a measurement of the delivered panel's accuracy.
Ports and a Docked Setup
The Lenovo platform lists Thunderbolt 4, a separate USB-C connection with DisplayPort and USB power delivery, HDMI, three USB-A ports and Ethernet. It has no card reader. A camera workflow may therefore need an external reader; an existing Thunderbolt dock can be worth checking before purchasing new accessories.
Confirm the dock's supported display modes, cable and charging output for the selected configuration. Use the supplied laptop adapter for gaming comparisons. USB-C charging support alone does not establish that a dock can sustain the same combined CPU and GPU workload as the main adapter.
Which Legion 5i Listing Are You Comparing?
Write down the processor, display, RAM and storage. A listing titled only “Legion 5i Gen 10” does not establish that it matches the configuration reviewed here. This is especially important when a retailer offers several display or processor choices under one product page.
The related benchmark system uses a different processor and panel. Its results can help explain the tested rendering modes, but they do not answer how this OLED configuration performs in the same game. Compare the actual purchase conditions and features you need while matching evidence is unavailable.
If the factory 32GB and 1TB already meet your requirements, avoid adding upgrade costs to the purchase by default. If storage is the constraint, the documented second slot provides an avenue to investigate before replacing a usable factory drive. Verify the mounting hardware and the seller's selected configuration first.

Battery Life
The linked configuration has an 80Wh battery. Runtime depends on brightness, refresh rate, OLED content, GPU state, workload, and power profile; related-configuration results are not reused as a matching estimate.
- RTX 5070 115W and OLED 165Hz combination
- 32GB DDR5-5600 and 1TB storage
- Upgradeable RAM and SSD
- Linked retail configuration is clearly identified
- Matching controlled gaming dataset is incomplete
- 8GB VRAM may constrain some high-resolution workloads
- Seller, warranty, and checkout price require verification

Jarrod’s Tech, checked September 15, 2026: single runs, maximum performance/fans, plugged in. These are points, not FPS or exact-retail measurements.
For game-specific comparisons, use Notebookcheck’s game database and inspect the contributing laptop, resolution and preset. Separate native rendering, upscaling and frame generation. In 3DMark result search, inspect the individual run and configuration before comparing; a leaderboard entry is not a typical retail result.
