Lenovo Legion 5 15IRX10 Review

Over the years, the “Lenovo Legion 5″ series has become one of the most reliable benchmarks for price-to-performance ratio in the gaming laptop market. Previous generations were known for their aggressive GPU power configurations (high TGP), but this often meant a massive chassis weighing over 2.4 kg, which was cumbersome to carry daily.
The 10th generation model, the “Lenovo Legion 5 15IRX10,” marks a clear turn: the chassis has become significantly thinner and lighter. Depending on the configuration, the weight starts at around 1.9 kg, and the thinnest OLED versions have a thickness of about 19.95–21.54 mm. This is a logical step into the “Thin & Light” gaming laptop segment, aiming to balance performance and mobility.
This design change is aimed at a broader audience:
– students who need a capable yet portable gaming laptop for lectures;
– developers and professionals looking for a hybrid device for work and gaming;
– gamers who value the convenience of transporting their laptop to work, travel, or LAN events.
This shifts the “Legion 5” away from the old paradigm of “thick and powerful” and brings it closer to higher-end work laptops while maintaining gaming power.

Intel and AMD Configurations and Pricing Logic

The “Legion 5 15IRX10” designation indicates an Intel platform model (IRX – Intel), but the overall 10th generation architecture (chassis, cooling system, display options) is closely related to the AMD versions, which use Ryzen 7 260 or Ryzen 7 8845HS processors. This gives users flexibility in choosing between high “single-core” performance (Intel HX) and more efficient power management (Ryzen).
On the graphics side, the “Legion 5” Gen 10 models are offered with the latest NVIDIA RTX 50 series mobile GPUs up to the RTX 5070 Laptop with 8 GB GDDR7 memory and a 128-bit bus. An important point: even in a thinner chassis, Lenovo maintains a high TGP – up to about 115 W (including ~15 W “Dynamic Boost”), so the GPU operates at “full power,” which is not always characteristic of thin gaming laptops.
Pricing in the market looks like this:

• In the US market: base configurations start at around $1,200, while more powerful variants with OLED and more capable GPUs range from $1,700 to $1,800.
• In the EU and Lithuanian market: RTX 4070 / 5070 class Legion 5 models typically cost around €1,550–1,800 (depending on RAM, SSD, display, and OS).

The key detail is that real value reveals itself during sales: the full retail price is often not exceptional, but during larger promotions, the “Legion 5” becomes one of the strongest offers in terms of price-to-performance ratio. This encourages buyers to actively monitor price changes and plan their purchases during discount periods.

Thin Chassis, Material Choices, and Port Layout Compromises

Materials and Construction

The 10th generation “Legion 5” design is minimalist, with a more subdued aesthetic than previous aggressive gaming chassis. The thinner profile is combined with refined lines and minimal LED “aggression,” making the laptop look neat in both gaming and work environments.
The chassis of the OLED versions is typically made from thinner aluminum parts, giving it a more “premium” feel. IPS models, especially the thicker versions, often rely on a mix of materials (metal and plastic), making them visually and tactilely feel slightly less exclusive, but still sturdy. This “material dichotomy” shows that maximum thinness and a more luxurious finish are prioritized specifically for OLED configurations.

Keyboard and Input Experience

The reputation of the “Lenovo Legion” series keyboards is maintained here. Key travel is ~1.6 mm, with a slight (about 0.3 mm) key indentation and a full-size arrow key block, allowing for comfortable work and intense gaming. It supports 24-zone RGB lighting or simpler white lighting, with a fully functional anti-ghosting mode (100%) to ensure no commands are missed when multiple keys are pressed simultaneously.

Ports and Aesthetic Trade-offs

The port selection on the “Legion 5 15IRX10” is extensive: HDMI 2.1, several USB-A, USB-C with DisplayPort and power support, RJ-45 Ethernet, headphone jack, and more. However, some design choices receive criticism:

• Side ports near the front: when connecting a wired mouse and USB stick or adapter, cables can interfere with mouse movement, especially for right-handed users.
• Removed rear port icons: in previous Legion models, icons for rear connections were visible on the top edge of the chassis, eliminating the need to flip the laptop. Now, due to a cleaner design, they are gone – making it less convenient for everyday use.

This is a classic example where aesthetic priorities slightly reduce ergonomics.

OLED vs. IPS and G-Sync Compromise

OLED – Visually Impressive but with Limitations

The high-end “Legion 5 15IRX10″ versions feature a 15.1” WQXGA (2560 × 1600) OLED display with a 16:10 aspect ratio. Typical features include:

• 165 Hz refresh rate;
• <1 ms response time;
• about 500 nits brightness and 100% DCI-P3 color coverage;
• perfect black and very high contrast, beneficial for HDR content and creative work.

The image looks extremely sharp, colors are vibrant, and the fast response time is excellent for gaming and video editing. Such specifications are still quite rare in this price segment.
The main downside is that this OLED panel does not support NVIDIA G-Sync, AMD FreeSync, or “Advanced Optimus.” This means there is no dynamic synchronization between the GPU frame rate and the display refresh rate, making “screen tearing” or micro-stuttering more likely, especially if FPS fluctuates significantly.

IPS – Less Impressive Image but More Gaming Features

IPS display options typically include:

• 15.6″ WQHD (2560 × 1440) 165 Hz IPS: ~350 nits brightness, 100% sRGB, about 3 ms OD response time, with G-Sync and MUX switch.
• 15.6″ FHD (1920 × 1080) 144 Hz IPS: ~300 nits brightness, 100% sRGB, about 25 ms response time, also with G-Sync and MUX.

The G-Sync and MUX switch allows the GPU frame rate to synchronize with the display and directly connect the discrete GPU to the panel, bypassing integrated graphics. This reduces latency and increases FPS, which is especially important in competitive gaming.

Strategic Choice Based on Purpose

In essence:

• OLED: ideal for creative work, movies, single-player AAA games where contrast and colors are paramount, and FPS fluctuations are less critical.
• IPS (WQHD with G-Sync and MUX): a more rational choice for eSports, fast shooters, and competitive games where maximum smoothness and stable frame synchronization are crucial.

CPU, RTX 50 Series GPU, and 8 GB Memory Limit

Processors: Intel HX and AMD Alternatives

In Intel versions, the “Legion 5 15IRX10” typically features the Core i7-14650HX or similar HX series processors. These are high-power mobile CPUs with a high power limit to achieve maximum multi-threaded performance (Cinebench, encoding, 3D rendering, etc.). AMD Ryzen 7 8845HS alternatives stand out for better energy efficiency and competitive CPU performance, especially regarding “performance per watt.”

GPU and TGP Maximization

One of the identity elements of the “Legion 5” is the uncapped GPU:

• RTX 5070 Laptop GPU – up to ~115 W TGP;
• RTX 5050/5060 – also operates at a high TGP level, consistently maintaining ~110 W load in real tests.

This allows the “Legion 5” to achieve performance close to larger, thicker gaming laptops while maintaining a thinner chassis.

8 GB VRAM – Long-term Risk

Mid-range RTX 4070 and 5070 laptops are often equipped with only 8 GB VRAM. In WQXGA (2560 × 1600) or especially 4K resolution, this becomes a bottleneck:

• high-resolution textures and ray tracing quickly consume VRAM;
• when VRAM runs out, FPS drops significantly, leading to micro-stutters;
• some older GPUs with 12 GB or 16 GB VRAM may perform better at very high settings.

If a long-term investment is planned and gaming with ultra-high-resolution textures is a priority, it may be worth considering the “Legion Pro” or other models with 12 GB VRAM and more.

DLSS 4 as an Essential Helper

To compensate for VRAM and performance limits, the latest RTX 50 series cards make “NVIDIA DLSS 4” extremely important:

• “Super Resolution” and “Frame Generation” features allow generating more frames per second from lower internal resolutions;
• DLSS 4, even in “Performance/Ultra Performance” mode, often provides sufficient image quality and allows utilizing WQXGA or even 4K monitors without sacrificing FPS;
• DLSS becomes not just an “additional plus” but a real necessity for those looking to serve future AAA games with 8 GB VRAM.

Practical tip: if you plan to play the latest AAA games at 2K/4K, when choosing the Legion 5, be sure to inquire about gaming DLSS support and be prepared to use this technology.

Thin Chassis, Full Power TGP, and Aggressive Thermodynamics

CPU – Constantly at the Limits

During long-term load tests, HX class Intel processors in “Legion 5” models operate at very aggressive power settings:

• CPU power around 75–80 W;
• average temperature under long-term load often approaches 99 °C;
• in “Performance” profile, P-cores maintain ~4.6–4.7 GHz clock speed.

This is not a defect but a conscious choice by the manufacturer: priority is given to maximizing the performance curve, allowing the CPU to operate at the thermal “throttle” limit. For the user, this means that under constant heavy task loads, the fans will run loudly, and the chassis will heat up more, especially above the keyboard.

GPU – Stable and Well-Cooled

The GPU situation is better balanced:

• In RTX 5050/5060 models, during long-term gaming, power is observed at about 110–115 W;
• GPU temperature usually remains within ~80–85 °C;
• VRAM temperature typically does not reach critical values.

This indicates that Lenovo clearly prioritizes graphics performance, as the GPU often determines FPS in games.

How Users Can Improve the Situation

Several real optimizations are available to users:

• Undervolting the CPU: allows achieving the same performance at lower power, often dropping several degrees and providing more “thermal headroom” for short boosts.
• Updating thermal materials: advanced thermal pads (e.g., PTM7950) and quality thermal paste can reduce CPU/GPU temperatures by up to ~10 °C, improving long-term stability.
• Usage habits: elevating the laptop off the desk, using a stand or cooling pad improves airflow and reduces temperature spikes during gaming.

These measures are especially relevant for those working with long-term 3D renders or transcoding videos and want the CPU not to constantly “hover” around the 99 °C limit.

Unusually Good Endurance for a Gaming Laptop and Excellent Upgradability

Battery Capacity and Real Endurance

The “Lenovo Legion 5” Gen 10 is offered with 60 Wh or 80 Wh battery modules. Tests show that with the 80 Wh pack and a balanced power profile, browsing the internet and working with office applications can achieve over 8 hours of working time – a very good result for a gaming laptop, surpassing many competitors that often limit themselves to 5–6 hours.
Additionally, the “Super Rapid Charge” feature is supported, allowing approximately 70% battery charge to be restored in about 30 minutes (specific values depend on the adapter and profile). AMD Ryzen models typically utilize energy even better, so if battery life is a priority, they become an attractive choice.

Upgrade Options

The “Legion 5” maintains its reputation as a “serviceable” gaming laptop:

• 2 SODIMM slots for RAM – up to 32 or 64 GB DDR5 (depending on the model);
• 2 M.2 NVMe SSD slots – allowing for the addition of a second drive or replacing the base with a larger and faster SSD;
• easily accessible fans, Wi-Fi module, speakers, battery.

This increases the device’s longevity: you can buy a more modest configuration and gradually expand it without purchasing a new laptop.

Omen and Helios Neo as Main Rivals

Price Ranges and Value Dynamics

In the European and Lithuanian markets, the Legion 5 Gen 10 with RTX 4070/5070 typically competes with the HP Omen 16 and Acer Predator Helios Neo 16:

• Lenovo Legion 5 Gen 10: around €1,550–1,800 for RTX 4070/5070 class models, with WQHD/OLED display and 80 Wh battery.
• HP Omen 16 (2024): similar level CPU and RTX 4060/5060 GPU, slightly shorter battery life (~6 hours), but often more aggressive promotions.
• Acer Predator Helios Neo 16: bright IPS displays (some versions even ~500 nits), but shorter battery life (~5 hours) and slightly larger dimensions.

What Sets the Legion 5 Apart?

In short:

• Battery: very good endurance for a gaming laptop – one of the standout advantages over Omen and Helios Neo.
• Thinner and Lighter Chassis: easier to carry daily while maintaining full GPU TGP.
• OLED Option: high-class contrast and colors at this price – a rare combination, even without G-Sync.

Meanwhile, competitors sometimes offer:

• a slightly brighter IPS display (Helios Neo);
• different design aesthetics or additional features (e.g., more RGB or extra ports).

Therefore, the final choice often depends on what is more important – battery endurance and OLED, or IPS brightness and other ergonomic details.

Practical Scenarios and Buyer Profiles

The “Lenovo Legion 5 15IRX10” shines in the following situations:

• Mobile Gamer and Student: needs a portable, thin gaming laptop that can be taken to lectures, work, and play the latest games in the evening.
