| Lenovo Legion 5 15IAX11 review: Optimized for 1440p gaming |
The gaming laptop market is fiercely competitive, and Lenovo has consistently delivered solid contenders with its Legion series. The 2026 Lenovo Legion 5 15IAX11 arrives with some intriguing upgrades, most notably the debut of Intel's new Core Ultra 7 251HX processor and a gorgeous 15.3-inch OLED display. But does this midrange gaming laptop deliver where it counts? I've been putting it through its paces to find out if it's the ultimate 1440p gaming machine for 2026.

Design and Build Quality: Familiar Yet Refined
The Legion 5 15IAX11 retains the same sleek, understated chassis design as its AMD-based sibling, the Legion 5 15AGP11 OLED gaming. At just 19.95mm thick and weighing under 2kg (1.946 kg), it's impressively slim and portable for a gaming laptop with this much power under the hood.
The design philosophy here is refreshingly mature. There are no aggressive angles or flashy RGB accents (well, the keyboard has single-zone RGB, but that's it). The clean, minimalist aesthetic means you could easily bring this to a coffee shop or meeting without drawing unwanted attention. The downside? It's an absolute fingerprint magnet, so keep a microfiber cloth handy.
The build quality feels solid, with no flex in the keyboard deck or lid. The 15.3-inch size is slightly unusual but yields a larger screen without increasing overall dimensions compared to the previous 15.1-inch model—a clever engineering feat.
Display: OLED Brilliance with a Glossy Catch
The standout feature of this review unit is undoubtedly the 15.3-inch 2560 x 1600 OLED panel. This is where the Legion 5 15IAX11 truly shines, quite literally.
Color coverage is exceptional:
- 100% sRGB coverage
- 99.9% DCI-P3 coverage
- 94.1% AdobeRGB coverage
Whether you're gaming, editing photos, or binging Netflix, colors pop with incredible vibrancy. The OLED panel delivers perfect blacks and an infinite contrast ratio, making dark scenes in games truly immersive.
Brightness is also impressive, peaking at 1076 nits in HDR mode and 484 nits in SDR mode. HDR content looks spectacular, earning this display its DisplayHDR1000 certification.
However, there's a significant caveat: the display is incredibly glossy or reflective. While this contributes to that crisp, vibrant picture quality, it can be distracting in well-lit environments. If you game near windows or under bright overhead lights, reflections may become an issue. Some gamers might find this a dealbreaker, especially compared to the matte IPS panels found on competitors.

Gaming Display Performance
The 165Hz refresh rate combined with OLED's near-instant response times (0.65ms black-to-white, 0.41ms grey-to-grey) means motion clarity is outstanding. There's virtually no ghosting, making this ideal for fast-paced shooters and racing games.
Key display advantages:
- G-Sync support for tear-free gaming
- Advanced Optimus for seamless graphics switching
- Perfect for HDR content
- Excellent color accuracy after calibration (dE of 0.59)
The screen supports G-Sync and Advanced Optimus, features relatively uncommon in the midrange segment. Adaptive sync ensures smooth gameplay without screen tearing or stuttering.

Performance: Arrow Lake's Debut
The Legion 5 15IAX11 marks the debut of Intel's Arrow Lake-HX architecture in the Legion lineup. Our review unit features the Core Ultra 7 251HX with 18 cores (6 Performance cores and 12 Efficient cores) and boosts up to 5.1 GHz.
CPU Performance
This processor represents a significant leap over last year's model:
- Cinebench R23 Multi-Core: 26,001 points - roughly 28% faster than the previous generation's Core i7-13650HX
- Cinebench R23 Single-Core: 1,941 points - competitive with AMD's latest offerings
- Blender BMW27 CPU: Completed in just 129 seconds, faster than many competitors
In Geekbench 6.7, the Core Ultra 7 251HX scored 14,233 in multi-core and 2,762 in single-core tests. While it can't quite match the top-tier Core Ultra 9 275HX found in machines like the MSI Crosshair 16 HX AI, it's a substantial upgrade over older Raptor Lake chips.
Real-world performance: In everyday tasks, web browsing, and productivity workloads, the system feels snappy and responsive. The 18 cores handle multitasking with ease, and the performance is consistent during extended workloads.
Gaming Performance
Paired with the NVIDIA GeForce RTX 5070 Laptop GPU (105W to 115W TDP), the Legion 5 15IAX11 is optimized for 1440p gaming. This is where the "sweet spot" moniker comes into play.
The RTX 5070 delivers excellent 1440p gaming performance. In most modern titles at high settings, you can expect smooth frame rates well above 60fps, with competitive games easily hitting the 165Hz refresh rate ceiling.
In 3DMark benchmarks, the performance rating of 91.5 puts it ahead of many similarly priced competitors, including:
- Asus TUF Gaming A15 FA507UV (90.5)
- MSI Katana A15 AI B8VG (85.4)
- Lenovo Legion 5 15IRX10 5070 (76.5)
The combination of the new CPU and RTX 5070 makes this an excellent 1440p gaming machine. For esports titles like Valorant or CS:GO, you'll easily max out the display's refresh rate. For AAA titles, you'll need to tweak settings, but high settings at 1440p are generally achievable.
RAM and Storage
Our test unit came with 16GB of DDR5-5600 RAM, but there's a catch: it's configured in single-channel mode. This can impact performance in some memory-sensitive applications and games. However, with two SODIMM slots available, upgrading to dual-channel is straightforward. Lenovo's decision to ship with single-channel RAM on a $2300 laptop is somewhat baffling but easily rectifiable.
Storage is handled by a speedy M.2 SSD, with two M.2 slots available for expansion. However, the review notes that the SSD may throttle under sustained heavy loads, which is something to monitor.
Cooling and Noise
The Legion 5 15IAX11 uses a familiar cooling solution with dual fans. On Performance mode, the laptop delivers impressive sustained performance, but it comes at a cost:
- Noise levels: The fans can become quite loud under heavy gaming loads. This isn't unusual for gaming laptops, but it's worth noting if you game in shared spaces.
- Temperatures: The system manages thermals reasonably well, though the keyboard deck can get warm during extended sessions.
There's also a quieter Balanced mode that reduces fan noise at the expense of some performance. For casual gaming or productivity, this mode is more than adequate.
Battery Life and Power
Battery life is a pleasant surprise for a gaming laptop. The 80Wh battery provides:
- Long runtimes when using the integrated GPU (iGPU) mode
- Respectable endurance for light tasks
- About 4-6 hours of mixed usage (web browsing, video playback)
While gaming, you'll definitely want to stay plugged in, but the improved efficiency of the Arrow Lake chip means you can actually use this as a portable machine for work or study.
The included power supply weighs 664 grams, keeping the total travel weight around 2.6kg—reasonable for a gaming laptop of this caliber.

- iperf3 receive: 1458 MBit/s on 6GHz band
The 1440p webcam is a notable upgrade over the standard 720p or 1080p cameras found on many gaming laptops, and it includes an electronic privacy shutter for security.
Keyboard, Trackpad, and Input
The Legion keyboard remains a highlight. The chiclet-style keys offer:
- Good travel and tactile feedback
- Comfortable arrow keys (unlike some cramped keyboard layouts)
- Single-zone RGB backlighting (not per-key RGB)
The single-zone lighting might disappoint some RGB enthusiasts, but the overall typing experience is excellent for gaming and productivity.
The trackpad is responsive and supports Windows Precision drivers, though most gamers will be using an external mouse anyway.
Software and User Experience
The laptop runs Windows 11 Home and comes with Legion Space, Lenovo's gaming software suite. It provides:
- Performance mode switching
- System monitoring
- RGB controls
- Gaming shortcuts
The software is functional if not particularly flashy. It gets the job done without being overly bloated, which is more than can be said for some competitors.
How It Compares to the Competition
vs. Razer Blade 16 (2026)
The Razer Blade 16 with Intel Panther Lake is a different beast entirely. At $4,900, the Blade 16 costs more than double the Legion 5's $2,300 price tag. However, it offers:
- Top-tier RTX 5090 graphics
- Thunderbolt 5 support
- Even better battery life
