I bet you have heard of the Lenovo gaming laptop product line, Lenovo Legion. You wanted to give it a try but just couldn’t trust the branding as most of the competitors (Acer Predator, ASUS TUF, ROG, and MSI) out there sound more professional and promising when it comes to the gaming side. But don’t worry, min min is here to review the Lenovo Legion 5i laptop (Intel i7-12700H) and find out whether the Legion 5i is a perfect laptop for gamers and creative creators who need powerful hardware to get their job done.


Design 💻

The Lenovo Legion 5i (15IAH7H) offers a professional look rather than the bulky body that most “gaming” laptops have as one of their characteristics. The Legion 5i on hand comes in Storm Grey colour. The Legion 5i weighs about 2.4kg which is standard for gaming laptops to have.

Besides, the Legion 5i provides plenty of ports at the back and on both sides. The available ports on Lenovo Legion 5i are listed below:


  • Ethernet (RJ-45)

  • USB-C 3.2 Gen 2

  • HDMI

  • USB 3.2 Gen 1

  • USB 3.2 Gen 1 (Always On)

  • Power connector


  • Thunderbolt 4

  • USB-C 3.2 Gen 2 (data transfer / DP 1.4 only)


  • Headphone/microphone combo jack (3.5mm)

  • USB 3.2 Gen1

The Legion 5i has a full-size keyboard with adjustable 4-Zone RGB via the Legion Spectrum RGB Lighting from preset RGB profiles in the Lenovo Vantage (built-in software).

The bottom of the Legion 5i is where the speakers and both cooling fans are located. Although the bottom of the laptop will not be seen most of the time. Lenovo nailed it by keeping the bottom of the Legion 5i looking minimal yet professional with the honeycomb ventilation panels.

Moreover, the Legion 5i has prepared four exhaust areas around the base to provide better cooling, delivering consistent fan curves and smooth framerates with zero throttling.



In terms of the display, the Legion 5i comes with a 15.6-inch WQHD (2560 x 1440) IPS 16:9 with a super-fast refresh rate of up to 165Hz refresh rate which means, you don't require to spend extra bucks for a second gaming monitor with a high refresh rate!

Pro-tip, the Lenovo Legion 5i performance mode can be adjusted according to the shortcut keys shown on the laptop, which is Fn + Q, switching between Quiet mode (power saving), Auto mode where AI will automatically tweak the performance based on the usage, and Performance mode (Max Power).

Aside from that, the Legion 5i display supports G-Sync technology which delivers the smoothest and fastest gaming experience by eliminating screen tearing and minimizing display stutter while gaming.

Before we move on to the other section, let me show you another cool trick you can pull off with the Legion 5i. Taa daa~ the display can be expanded for up to ~180° hinge, laying flat on the table which is quite efficient to showcase their work to others (also for more comfortable use).


Specifications ✨

Now, the interesting part of the Lenovo Legion 5i. The Legion 5i is equipped with a 12th Gen Intel Core i7 12700H processor and an NVIDIA RTX 3060 6GB GDDR6 graphics card. Both of this hardware is enough to run most of the games (of course don’t expect to run it smoothly on max settings Triple-A games).

Other than that, it supports up to 32GB of DDR5 (2 x 16GB) 4800MHz frequency RAM and a storage capacity of 1TB PCIe Gen 4 SSD. To be relevant, the Legion 5i uses Windows 11 Home as its operating system.

While unplugged, the Lenovo Legion 5i can last for nearly 2 hours of normal operation with balanced power settings which is normal for gaming laptops as it mainly focuses on performance.

However, if you insist on bringing out the Legion 5i outdoors for work or education purposes, you might need to turn on the thermal mode to lower power consumption. Also, the Legion 5i packs a 230W AC Adapter that supports Rapid Charge to juice up the laptop to 80% for a 30-minute charge as advertised.

I don’t get the rain puddles so I’ll have to show it by the building’s reflection ;-; Basically, without Ray-tracing on, the reflections will be replaced by some sort of clipart instead of legit reflection. Nonetheless, you will still see some minor reflections on some buildings (which is kinda unnoticeable).
