Both laptops run the exact same full-power 175W RTX 5080 GPU, and the benchmark results reflect that. In 3DMark Time Spy, the gap between the two is less than 2% — well within margin of error. In real-world gaming at 1600p, frame rates in demanding titles like Cyberpunk 2077 and Black Myth: Wukong are effectively identical. Where it gets interesting is sustained performance. Lenovo’s vapor hyperchamber cooling allows the Legion to sustain its 250W combined CPU+GPU power output for extended sessions without throttling. MSI’s OverBoost Ultra pushes 240W, which is competitive but not quite as aggressive. In multi-hour stress tests, the Legion holds a 3-5% edge in sustained GPU clock speeds — a difference you won’t notice in a 20-minute session but might feel during a marathon.

This is the single biggest differentiator between these two machines, and it’s not close. The Legion’s 16-inch OLED panel delivers 100% DCI-P3 color coverage, a Delta-E under 1.5 (essentially factory-calibrated accuracy), and 500 nits of brightness. The infinite contrast ratio of OLED means that dark scenes in games are rendered with a depth and detail that IPS panels physically cannot reproduce. The Vector’s IPS display is good — it’s a 240Hz 2560×1600 panel, and for pure gaming it’s perfectly serviceable. But place them side by side and the difference is obvious. If you do any creative work alongside gaming, the Legion’s display alone justifies its price premium.

Lenovo has clearly invested more in the Legion’s industrial design. The chassis feels solid and refined — the keyboard is excellent with good travel and feedback. Customer reviews consistently praise the quality of materials. The MSI Vector takes a more utilitarian approach. It’s not poorly built but the aesthetic leans heavily “gamer.” Early Amazon reviews (3.4/5 with 21 reviews) flag some quality control concerns, though it’s worth noting this is a small sample size. Both weigh exactly 5.95 lbs.

The Legion Pro 7i’s vapor hyperchamber cooling system is one of the best in the industry. Under full gaming load in Balanced mode, the laptop remains surprisingly quiet while sustaining peak performance. The MSI Vector in Extreme mode is what multiple reviewers describe as “audible across a room.” In Balanced mode, the Vector is much quieter but gives back some performance. For users gaming with headphones, the noise difference may be irrelevant.

MSI takes this category cleanly. The Vector 16 is one of the first gaming laptops to ship with Thunderbolt 5, which doubles the bandwidth of Thunderbolt 4. Both machines have Wi-Fi 7. Neither includes an SD card reader.

At approximately $2,499, the MSI Vector 16 is the cheapest full-power 175W RTX 5080 laptop on the market. The Legion Pro 7i starts at roughly $2,849. What does $350 buy you? A dramatically better OLED panel, quieter thermals, and a more refined chassis. The Vector also ships with 2TB of storage versus the Legion’s 1TB.
