Lenovo Legion 5 15IRX10 Review

The concept and market position of the new generation Legion 5 15IRX10

Over several generations, the Lenovo Legion 5 series has earned a reputation as one of the best balances of price and power in the gaming laptop world. Previous models were often massive, 2.4 kg or even heavier “bricks” that cooled RTX graphics cards well but were not convenient for daily transport. The new tenth generation, which includes the Lenovo Legion 5 15IRX10, radically changes this philosophy – it is no longer “thick and powerful” but thin and fully powered gaming laptop.

From the official specifications, it can be seen that the 15-inch Gen 10 model weighs about 1.9 kg, and the thickness of the chassis ranges from approximately 20 to 24 mm, depending on the configuration.

This already falls into the “thin & light” category, but with components that have typically been installed in much thicker cases until now.

Market niche and target audience

The Legion 5 15IRX10 is aimed at a broad segment:

gamers who need true RTX 50 series performance but do not want a 3 kg “monster”;

students and young professionals who need one machine for both studies and AAA gaming;

representatives of creative professions (photo/video, 3D, graphics) for whom color accuracy is important, but who also want to unwind with gaming in the evening.

The series offers both AMD and Intel platforms. Intel variants are marked as 15IRX10, while AMD models are labeled as 15AHP/15AHP10; architecturally, they share the same chassis and cooling, differing only in processors and some connectivity solutions (e.g., USB4 in Intel versions).

Price level and real value

In Lithuania and the broader EU market, the Legion 5 15IRX10 and similar AMD models with RTX 5050/5060/5070 typically range from approximately €1100–1200 for simpler configurations to around €1700–1800 for more powerful models with OLED screens and RTX 5070.

These prices are not revolutionary in themselves, but Lenovo’s strategy relies on frequent sales – real value emerges when you manage to hit a 20–30% discount. At that point, the Legion 5 becomes one of the most attractive mid-range gaming laptop offerings.

Chassis, materials, and input quality

Minimalist yet “legion-like” chassis

The Gen 10 Legion 5 design is understated and clean: more “gray ultrabook,” less aggressive gaming “wings.” The chassis measures about 344.9 × 255.4 mm, with thickness ranging from ~19.95 mm at its thinnest to ~23–24 mm at its thickest, and weighs around 1.9 kg.

In OLED configurations, aluminum and a sturdier top are more emphasized, making the device look like a more expensive, “pro” class ultrabook. IPS variants may have more plastic, but the overall construction remains solid and free of creaks. This material “dichotomy” reflects different segmentation: OLED is more for hybrid, creative work, while IPS is more for gaming.

Keyboard and touchpad: for gaming and long typing sessions

The “TrueStrike” type keyboard remains one of the strongest features of the Legion family. Key travel is about 1.5–1.6 mm, with slightly concave keycaps, making it comfortable for touch typing. There is a full numeric keypad, and for gamers, it is important:

100% anti-ghosting feature;

multi-zone RGB lighting (or subdued white lighting in cheaper versions);

comfortable arrow key zone, not cramped between other keys.

The touchpad is larger than in previous Legion generations but still quite conservative: accurate, sufficiently smooth, but gamers will likely still opt for an external mouse.

Ports and ergonomic compromises

The selection of ports is very solid: several USB-A, two USB-C (including DisplayPort and Power Delivery), HDMI 2.1, RJ-45 network socket, 3.5 mm audio jack.
However, there are two design decisions that raise criticism:

some side ports are positioned very close to the front of the chassis, so connected USB drives or cables may obstruct mouse movement;

the convenient rear port icons above the connectors, which allowed for “eyeballing” where HDMI or power was, have been removed.

This is a classic case where visual cleanliness has triumphed over ergonomics.

OLED vs. IPS – the visual “wow” and G-Sync dilemma

WQXGA OLED: impressive contrast and colors

The high-end Legion 5 15IRX10 configurations offer a 15.1″ WQXGA (2560 × 1600) OLED display with a 16:10 aspect ratio and a 165 Hz refresh rate.

Official data and reviews mention:

~500 nits brightness for HDR content;

almost perfect black levels and “infinite” contrast;

100% DCI-P3 color coverage;

<1 ms response time.

In practice, this means that games, movies, and creative work (video editing, photography, design) look significantly better than on standard IPS displays. The only downside is the glossy surface, which will reflect in bright environments.

IPS options and adaptive synchronization

For those who prioritize stable frame rates and smooth gaming, IPS panels remain very relevant. In the Legion 5 family, regionally you can find:

15″ WUXGA (1920 × 1200) 165 Hz IPS;

in some markets – simpler FHD 144 Hz IPS variants.

The main difference is in feature support:

IPS panels support NVIDIA G-Sync (or at least “G-Sync Compatible”) and a MUX switch that allows connecting the display directly to the discrete GPU;

the OLED panel lacks both G-Sync and Advanced Optimus / FreeSync – it operates in standard hybrid graphics mode.

This presents an important dilemma: OLED provides the best image, but IPS with G-Sync offers the most stable and “cleanest” motion without screen tearing.

Display comparison summary

If visual quality, HDR, and creative work are your main concerns, OLED is the clear winner. If your priority is eSports and maximum smoothness, IPS with G-Sync and MUX will be the more rational choice.

CPU, GPU, and VRAM limits of the Legion 5 15IRX10

HX class Intel and efficient Ryzen

The Intel-based 15IRX10 is typically equipped with “Core i7-13650HX” or similar HX class processors. These are high-power chips, with short-term power limits reaching 130–140 W and long-term limits around 90–100 W.

This configuration allows for:

extremely fast multi-threaded performance in rendering, compiling, or using complex work applications;

high frame rates in games where CPU performance is crucial (FPS shooters, strategy games).

AMD alternatives (e.g., Ryzen 7 260 / 8845HS) offer very similar gaming performance but generally feature better energy efficiency and quieter cooling.

If battery life and cooler chassis are priorities, the AMD option often becomes a “secret favorite.”

RTX 50 series and full TGP

The graphics subsystem is the main star of the Legion 5 series. Gen 10 models offer RTX 5050, RTX 5060, and RTX 5070 laptop GPUs, and here Lenovo adheres to tradition: no aggressive TGP capping just for the sake of thinness.

The RTX 5070 Laptop GPU in the Legion 5 15IRX10 can operate at up to ~115 W TGP (including dynamic Boost).

Tests with the RTX 5050 show an average sustained power of about 110 W – indicating that the cooling allows the GPU to run “full throttle” without constant throttling.

Many other thin gaming laptops simply do not reach such TGP levels – they often limit themselves to 80–95 W to keep temperatures and noise down.

8 GB VRAM – sufficient today, may limit tomorrow

The biggest architectural downside of these mid-range RTX 40/50 GPUs is the only 8 GB VRAM and relatively narrow bus. This means:

for 1080p and 1440p resolutions, this is sufficient today, as long as texture quality is not pushed too far;

WQXGA (2560×1600) or 4K without DLSS becomes a serious challenge for the latest AAA games, especially with ray tracing – VRAM fills up quickly, and performance drops disproportionately.

If you plan to play only on the integrated WQXGA screen and use DLSS, this limitation is more theoretical. However, looking at a 3–5 year horizon, VRAM may become a “bottleneck” compared to “Legion Pro” models that have 12 GB or more.

DLSS 4 as a strategic weapon

RTX 50 series Legion 5 models support the latest “NVIDIA DLSS 4” technology, which, according to official NVIDIA and Lenovo information, utilizes “Multi Frame Generation” and enhanced Super Resolution and Ray.

In practice, this means:

significantly higher frame rates by generating additional frames between those actually rendered;

lower VRAM pressure, as some of the video calculations are offloaded to AI models;

better image quality in more aggressive performance modes.

For those looking to leverage the potential of the WQXGA OLED display, DLSS 4 is not just a “nice addition” – it becomes an essential technology to avoid the “8 GB VRAM” limitations.

Thin chassis and aggressive thermodynamic strategy

CPU – at thermal “ceilings”

The thin chassis and high power limits inevitably pose cooling challenges. In long-term load tests, the HX class Intel processor (e.g., i7-13650HX) often operates close to the 99 °C limit at ~75–80 W sustained power. Such temperatures are not a defect – this is a conscious “Lenovo” decision that allows for very high P-core clock speeds (~4.6–4.7 GHz) in multi-threaded tasks.

In short, the Legion 5 prioritizes maximum performance, not maximum comfort in terms of noise and temperatures.

GPU – balanced and stable

On the other hand, GPU cooling is more efficient:

during long gaming sessions, the RTX 50xx GPU maintains ~110 W power;

average GPU temperature hovers around the 80–85 °C mark;

VRAM temperatures remain safe, so the risk to the chips does not increase over time.

Since most games are more dependent on the GPU, this prioritization is understandable – the system allocates a “fatter” slice of thermal resources to the graphics card.

Noise level and enthusiast optimization

During intense gaming, the fans run loudly – this is not a quiet ultrabook. However, several strategies are offered:

switching profiles to “Balanced” or “Quiet” mode when maximum FPS is not needed;

CPU “undervolting” (reducing voltage) – a popular enthusiast practice that can lower temperatures by several degrees while maintaining similar performance;

upgrading thermal interface materials (e.g., PTM7950 pads and quality thermal paste) – some enthusiasts’ tests show double-digit temperature reductions.

Such improvements require experience and careful execution, but they allow squeezing more comfort out of the thin chassis.

Battery, RAM / SSD, and longevity

Battery capacity and real workday

The Legion 5 Gen 10 can be equipped with a 60 Wh or 80 Wh battery, but the 80 Wh version is most commonly found in Lithuania and the EU.

Tests show that, under a balanced profile, reduced screen brightness, and browsing/office tasks, it can achieve over 8 hours of operation. This is an exceptionally good result for a gaming laptop, surpassing many competitors (HP Omen, Acer Helios Neo), which often stop at 5–6 hours.

AMD models shine even more here – due to more efficient Ryzen chips, they can squeeze out an extra hour or more. Some Legion 5 models also support “Super Rapid Charge,” allowing for about 70% charge in approximately half an hour.

Upgrade potential

One of the arguments for choosing the Legion series is its very good upgradability:

two SODIMM slots for RAM (up to 96 GB DDR5);

two M.2 2280 PCIe 4.0 x4 slots for SSD storage;

fairly easily accessible fans, Wi-Fi card, speakers.

Practically, this allows for:

buying a cheaper base configuration with 16 GB RAM and 512 GB SSD;

later self-installing 32–64 GB RAM and 1–2 TB SSD for significantly less than the manufacturer’s upgrades.

Such features make the Legion 5 not only a powerful but also a long-lasting purchase.

Lenovo Legion 5 vs. HP Omen and Acer Helios Neo

Price and specification comparison

Direct competitors to the Legion 5 in the mid-to-upper range include:

HP Omen 16 (RTX 4060 / 5060);

Acer Predator Helios Neo 16 (RTX 4060).

The price level is similar – around €1300–2000 depending on GPU, display, and RAM/SSD.

The Legion 5 stands out by being able to offer “Pro” level battery life and full TGP GPU in a thinner chassis with an OLED option. However, competitors sometimes win on:

price – Omen is often cheaper during sales;

IPS brightness – some Helios Neo displays reach nearly 500 nits, which is useful in bright environments.
