Lenovo Legion 7i Gen 10 Review: The Good, The Limits, and The Quirks

Lenovo Legion 7i Gen 10 Review

The Lenovo Legion 7i Gen 10 is a beast when it coms to everyday gaming and everyday tasks, but does have real limits depending on your workload. These limitations can mostly be addressed there are upgrade paths for RAM and SSDs but it’s worth knowing what you’re getting into before you buy.

Lenovo Legion 7i Gen 10 Storage: PCIe Gen 5 Explained

The configuration I purchased shipped with two 1TB NVMe drives, both PCIe Gen 4. Although Lenovo does not mention this on their website, the Intel Ultra 9 275HK supports PCIe Gen 5 x4 on one of the M.2 slots. This can be verified on the processer specification located on the Intel website. Although this seems like an easy upgrade win for higher transfer speeds, the actual speed difference in day-to-day activities is negligible, with the only real advantage being in transferring large files at high speed (film editing, etc.) or possibly some Large Language Model (LLM) work where RAM is swapped to the SSD drive.

PCIe and RAM configurations

If you have been searching the internet to investigate if the Gen 10 supports PCIe Gen 5, look no further, I have done the research, and both HWiNFO and Intel data confirm support for this generation (Gen 5).

Above: If you look closely at the specifications for the Intel 275HX, we can see how the PCIe buses are divided between PCIe 4 and PCIe 5:

Above NVMe: PCIe Gen 5 x4

Above RTX 5070: PCIe Gen 5 x8 — reduced bandwidth due to only having access to 8 PCIe lanes rather than 16 like full-size GPU models.

Lenovo Legion 7i Gen 10 RAM: The Real Limits

The laptop ships with 32GB of RAM in my configuration. Although this seems like a lot of RAM, it satisfied my needs for gaming and day-to-day work — but I quickly realized there were limitations with regards to local LLM models. The Intel Ultra 9 275HX supports up to 256GB of RAM, but with the cost of RAM these days, the upgrade seems risky, as I value my marriage more than my laptop. You can always check Facebook Marketplace or other auction sites for deals, but beware of scams. I cannot confirm that the 7i works at 6400 MT/s, as the device ships with OEM 5600 MT/s RAM.

Lenovo Legion 7i Gen 10 Battery Life

You don’t buy a gaming laptop for battery life — you buy one for its specific use: gaming, LLM work, design, pure power, etc.

Expect the battery life to be disappointing if you are doing anything other than writing emails and general office-type activities with energy saving on and the screen dimmed — expect 2 to 3 hours if you’re lucky. Trust me when I say this, and other reviews will echo this. If you’re looking for laptop with long battery life that will easily last a full workday while you are on the go, look elsewhere.

Docking Station Compatibility

The 7i has an interesting quirk when using a docking station that charges through USB-C and is also used as a display. The Thunderbolt 4 USB-C port does NOT charge the device. Although this is not a huge problem for me, it may cause pain and suffering for others, as USB-C docks supporting Thunderbolt 4 (and peripherals) will not work at the full 40Gbps rated speed. This is not something you can change, so don’t bother looking at docking stations that support this. This is a known BIOS issue and was likely intentional on Lenovo’s end to accommodate the switching of integrated and dedicated graphics.

Screen

The screen is beautiful! Coming from an Ultrabook with a 13″ screen and also my beefy 8lb 17″ Dell work laptop, the 16″ screen is really the perfect transition from work to home use. It’s not the greatest for gaming, especially when playing first-person shooters like Battlefield 6 — but it works fine for other titles (think: really small targets to shoot at). If the screen size is an issue, the 7i has a conveniently located full-size HDMI port on the back, which is where all HDMI ports should be located on laptops are you reading this, Asus, HP, and Dell? I have also tested the Legion 5 Gen 10, and all ports (even the power port) are located on the left and right sides, which seems silly and they get in the way.

CPU

There are a ton of cores — 24 performance cores, to be exact. I would have never thought having this many cores in a consumer laptop would have been possible in my lifetime, given the needs of most individuals (browsing the web, Facebook, Pinterest, etc.). But with 24 cores and 24 threads, this laptop packs a punch! Not to mention it also has NPU cores (for AI work), which are horribly underutilized — the only way I’ve been able to use them is with Microsoft Teams’ “eye tracking,” and you look weird to other people in the meeting. I’M ALWAYS LOOKING AT YOU!

Pricing & Value

You’re probably wondering what I paid for my 7i back in November 2025 during the Black Friday sales. The answer: $2,200 + tax — a steal considering the increased costs of SSDs and RAM these days, with the same laptop now selling for $4,000+. If you can hold out and watch for good deals, Lenovo constantly has sales and clearance events. If you’re thinking of getting the Lenovo 7a (AMD version) Gen 11, you should be aware that the upgrade paths are limited, as the RAM is soldered on. Also, the new models ship with an RTX 5060 as their highest-tier GPU.

Size and Weight

The main reason I selected this laptop over other Lenovo laptops was is size and weight. It weighs in at 1.99kg or 4.39lbs making it very lightweight considering its made from very high quality material and a metal chassis. My previous laptop I was hauling back and forth to work weighed a respectable 8lbs, so this was a welcome upgrade for my back and shoulders. The laptop is very this as well making is look sleek and high tech when displayed.

Screen

The OLED screen is crisp, clear, and beautiful with very respectable brightness, but do keep in mind there is glare and no anti-reflective coating on the screen (to my knowledge). The built-in Windows Night Light for eye protection is a nice touch, but it is not exclusive to Lenovo — so just ignore that sentence.

Conclusion

I have never had so many people ask me “what laptop is that” and I tell them it’s a Lenovo – it rally looks like it might be item displayed on the work desk in the future. The design and aesthetics are quite stunning. The Lenovo Legion 7i Gen 10 is an excellent gaming laptop with powerful specs and solid performance, though it comes with some limitations. If you’re planning to set up a complete gaming workstation, you may also want to consider accessories like the best laptop stands that actually work to improve ergonomics, or a quality gaming monitor to complement your setup.
