The Lenovo Legion 5i Gen 10 (2025) 15″ is a gaming laptop with a 21 mm thin profile and a footprint of 344 mm wide by 255 mm deep, giving it a total volume of 1,842.12 cm³. It weighs 1,900 g, which is typical for a machine in this category. The chassis does not follow a fanless design, nor does it carry weather-sealed or rugged certifications, so it is intended for indoor use in standard conditions. A backlit keyboard is included, adding usability in low-light environments.
The laptop features a 15.1″ OLED/AMOLED panel with a resolution of 2560 x 1600 px and a pixel density of 199 ppi, delivering a fairly sharp image across its surface. It has a typical brightness of 500 nits and a 165Hz refresh rate, making it well-suited for fast-moving content. The display does not support touch input and lacks an anti-reflection coating. The system can drive up to 4 displays simultaneously, including the built-in screen.
The system is powered by a CPU with 28 threads, base clock speeds of 8 x 2.1 GHz and 12 x 1.5 GHz, and a turbo frequency reaching 5.5GHz, built on a 5 nm semiconductor process with multithreading support. It comes with 32GB of DDR5 RAM, expandable up to 192GB, paired with a 1024GB NVMe SSD using flash storage and a PCIe 5 interface. The discrete GPU runs at a base clock of 952 MHz and boosts up to 1455 MHz, delivering 9.684 TFLOPS of floating-point performance alongside a texture rate of 151.3 GTexels/s and a pixel rate of 46.56 GPixel/s, backed by 8GB of GDDR7 VRAM. The GPU supports DirectX 12 and is 64-bit capable, though it does not include XeSS (XMX) support.
In standardized benchmark testing, the laptop recorded a Geekbench 6 multi-core score of 13,529 and a single-core score of 2,504, reflecting the CPU's threading capacity alongside its per-core output. On the PassMark suite, it achieved an overall score of 37,155, with a single-thread result of 3,987.
The laptop's port selection includes two USB 3.2 Gen 2 Type-C ports and three USB 3.2 Gen 2 Type-A ports, with no USB 4, Thunderbolt 3, or Thunderbolt 4 ports present. Video output is handled by a single HDMI 2.1 port, while DisplayPort, mini DisplayPort, and VGA outputs are absent. Wired networking is covered by one RJ45 port, and wireless connectivity spans Wi-Fi 7 (802.11be) down through Wi-Fi 4 (802.11n). AirPlay is supported, but there is no external memory slot and no USB 2.0 ports.
The laptop includes sleep-and-charge USB ports, allowing connected devices to be charged even when the system is powered off or in sleep mode. It does not use a MagSafe power adapter.
On the audio side, the laptop features stereo speakers and a 3.5 mm headset jack, though it lacks Dolby Atmos and an S/PDIF output. A 5MP front camera is built in, accompanied by a single microphone; however, there is no fingerprint scanner, 3D facial recognition, or voice command support. The GPU supports ray tracing and DLSS, adding to its graphics feature set. No stylus is included, and the device does not carry sensors such as a gyroscope, accelerometer, compass, or GPS, nor does it have an optical disc drive.
The CPU is a laptop-class processor with a 45W TDP, a clock multiplier of 21, a maximum operating temperature of 100°C, and 33MB of L3 cache, supporting big.LITTLE technology, the NX bit, and instruction sets including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2; the multiplier is locked. It includes integrated graphics (UHD Graphics 770) with 32 execution units alongside the discrete GPU, which is based on the Blackwell architecture and houses 3,328 shading units, 104 TMUs, 32 ROPs, and 21,900 million transistors, with a memory bus width of 128-bit, an effective memory speed of 28,000 MHz, and a maximum memory bandwidth of 448 GB/s. The system supports Intel Resizable BAR, ECC memory, Double Precision Floating Point, stereoscopic 3D, and multi-display output, and is compatible with OpenCL 3 and OpenGL 4.6. RAM runs at up to 5,600 MHz across two memory channels, and the overclocked PassMark result stands at 39,466. LHR is not present.
