There are laptops built for multitasking, and there are laptops built for domination. The Lenovo Legion 5 with Intel Core i7-14700HX and RTX 5070 looks like a machine built to do both, but it only proves its worth when we test the device, hence this review.
Specs alone don’t guarantee results. What matters is whether it stays cool when the heat rises, holds frame rates when games become demanding, and performs consistently when switching from work to entertainment. With an SRP of PHP 133,995, it steps into a segment that expects no shortcuts. Is it ready for that challenge?

Design and Construction
The Legion 5 15IRX10 carries Lenovo’s reputation for sturdy yet stylish gaming laptops. The aluminum top cover combined with a PC-ABS bottom reinforced with 15% talc provides both rigidity and a premium feel without adding excessive weight. The overall form factor is relatively compact for a 15-inch gaming laptop, and the chassis is solid with minimal flex under normal use.
The display hinge allows tilting up to 170 degrees. Attempting to tilt further could damage the hinge, but the range is sufficient for most use cases, from gaming to content consumption. Overall, the build balances durability, premium feel, and thermal management reasonably well.
The keyboard is a highlight for both gaming and typing tasks. It features a 24-zone RGB backlight that can be customized through Lenovo’s software, providing a satisfying tactile response. The palm rest remains comfortable even during extended sessions, and the touchpad is large, smooth, and responsive.
Port selection is thoughtful, offering users flexibility without clutter. There is a , one USB-A 5Gbps, one USB-A 5Gbps with Always On charging, and one USB-C supporting USB 10Gbps and DisplayPort 1.4. On the right, another USB-A 5Gbps port is available along with the headphone/microphone combo jack (3.5 mm) and the camera privacy toggle, and the rear houses the main exhaust vents for the cooling system along with the HDMI port and the power port.
The cooling design, Lenovo’s ColdFront 5.0, uses dual fans and a vapor chamber to manage heat. Airflow is generally effective, though under extreme loads the fans ramp up significantly, which can lead to higher surface temperatures around the WASD area and bottom panel.
Display and Multimedia
The 15.1-inch OLED panel is a standout feature, offering exceptional color accuracy and contrast. With a resolution of 2560×1600 and 165 Hz refresh rate, it provides smooth motion for gaming and productivity tasks. The OLED technology ensures true blacks and a near-infinite contrast ratio, while HDR True Black 600 support delivers deep colors and dynamic range. Brightness averages around 500 nits, enough for most indoor and moderate outdoor conditions.
Color accuracy is excellent, with Delta E values around 1.2–1.5, making it suitable for content creators who require precise color reproduction. Dolby Vision support enhances HDR content, delivering punchy highlights and richer shadows. The high refresh rate combined with fast pixel response times ensures gaming feels fluid, particularly for competitive esports titles where frame timing is critical.
The audio system uses two 2W Harman speakers optimized with Nahimic Audio. While not comparable to external desktop speakers, the output is clear and detailed for a laptop. Audio imaging is sufficient for gaming, and the inclusion of the Nahimic software allows for some customization of EQ and spatial effects.
The 5 MP webcam with an electronic shutter offers a clear image for video calls or streaming. The electronic shutter enhances privacy and eliminates the need to attach a physical cover. Connectivity is robust: Wi-Fi 7 ensures high throughput and future-proofing, while Bluetooth 5.4 provides reliable peripheral connectivity. The combination of HDMI 2.1, USB-C with DisplayPort, USB-A, and Ethernet allows users to connect multiple displays, storage devices, and networking hardware without relying on adapters.
Performance
The Lenovo Legion 5 15IRX10 is built for performance. Its Intel Core i7-14700HX CPU, with 20 cores (8 performance and 12 efficient), offers a large performance ceiling for both single-threaded and multi-threaded workloads. Benchmarks show the CPU scoring around 7,200–7,400 points in Cinebench R26 single-core tests and 35,000–36,500 points in multi-core tests, confirming that it can handle complex productivity tasks like compiling, 3D rendering, or video encoding without compromise.
The NVIDIA RTX 5070 8 GB GPU delivers strong performance for gaming at 1080p and is capable of 1440p gaming at high settings. Competitive titles like Valorant, CS:GO, and DOTA 2 can easily exceed 220 FPS, taking full advantage of the 165 Hz display. AAA titles such as Cyberpunk 2077 at ultra settings average around 38–42 FPS, which can be improved to 60–65 FPS using NVIDIA DLSS 3. Other games like Assassin’s Creed Valhalla and Red Dead Redemption 2 run comfortably at 55–60 FPS on high settings.
Storage and memory speed contribute significantly to system responsiveness. The NVMe SSD ensures near-instant application launches, and multitasking with multiple demanding applications does not cause bottlenecks under typical workloads. Memory upgrades, as noted, would further enhance performance in scenarios that rely heavily on RAM bandwidth, such as complex simulation software or extremely large gaming maps.
Storage performance is exceptional. The 1 TB NVMe SSD offers sequential read/write speeds of approximately 7,000/5,500 MB/s, and 4K random read/write in the range of 150–180k IOPS. This results in fast boot times, minimal loading delays in games, and overall snappy system responsiveness.
Memory is currently configured as 24 GB DDR5-4800 in a dual-channel layout (2×12 GB), which is sufficient for multitasking and gaming. However, there is room for improvement: upgrading to faster RAM or a larger dual-channel configuration (e.g., 2×16 GB DDR5-5600) would alleviate the memory bottleneck suggested by certain benchmarks, improving both CPU performance and frame rates in memory-intensive games.
The system’s overall PassMark Rating of 11,930.2, which places it in the 91st percentile, confirms that this is a high-end laptop capable of handling demanding tasks across gaming, content creation, and productivity.
The Legion 5’s performance is impressive but comes with considerations. Under heavy loads, the CPU and GPU reach peak temperatures of approximately 90 °C, with the WASD area and bottom panel reaching 42–50 °C. The dual-fan ColdFront 5.0 cooling system is effective but may require manual fan tuning or undervolting for sustained maximum performance. The GPU, although strong, can be limited by Optimus in certain scenarios, which may cause minor performance dips if not configured correctly.
In gaming scenarios, the system consistently delivers competitive frame rates. E-sports titles benefit most from the high refresh rate display, while AAA titles perform well with DLSS and RTX features enabled. Multi-threaded productivity tasks, including video encoding, 3D rendering, and heavy multitasking, are handled efficiently thanks to the i7-14700HX and dual-channel memory.
Battery and Charging
Battery life on the 80 Wh battery is moderate given the high-performance components. In light use scenarios such as web browsing and office tasks, the Legion 5 can last between 4–5 hours. Gaming or content creation workloads, especially those engaging both CPU and GPU, can reduce battery life to around 1–1.5 hours. The included 245 W Slim Tip power adapter ensures that the laptop can maintain peak performance while plugged in.
The Rundown
The Lenovo Legion 5 15IRX10 is a premium, versatile laptop that balances high-end gaming capabilities with serious productivity performance. It is well-suited for gamers, content creators, and professionals who need a portable system capable of handling demanding workloads without compromise. Its OLED display, fast NVMe SSD, and dual-channel memory enhance usability and responsiveness, while the Intel i7-14700HX and RTX 5070 combination ensures excellent performance across a range of scenarios.
The Lenovo Legion 5 15IRX10 (83LY003FPH) is currently available in stores and online for PHP PHP 133,995.
