The Lenovo Legion Slim 5 16AHP9 is a gaming laptop with a 19 mm thickness and a footprint of 359 mm wide by 260 mm deep, giving it a total volume of 1773.46 cm³. It weighs 2300 g and features a backlit keyboard, while relying on an active cooling system rather than a fanless design. The chassis is not weather-sealed, so it offers no splash protection. Lenovo backs the unit with a 2-year warranty.
The laptop features a 16-inch IPS LCD panel with LED backlighting, running at a 2560 x 1600 resolution that translates to a pixel density of 188 ppi. It supports a 165Hz refresh rate, which suits fast-paced content, and reaches a typical brightness of 350 nits. An anti-reflection coating is present, though the display does not support touch input. The system can drive up to 4 displays simultaneously.
The processor runs 8 cores at a base clock of 3.8 GHz with a turbo speed of 5.1 GHz, supporting 16 threads and multithreading, and is built on a 5 nm process node. Paired with it are 32GB of DDR5 RAM at 5600 MHz across 2 memory slots, with a maximum supported capacity of 64GB. Storage is handled by a 1024GB NVMe SSD using flash memory and a PCIe 4.0 interface. On the graphics side, the GPU carries 8GB of GDDR6 VRAM, a base clock of 1545 MHz boosting to 2370 MHz, and delivers 14.56 TFLOPS of floating-point performance alongside a texture rate of 227.52 GTexels/s and a pixel rate of 113.76 GPixel/s. The system supports DirectX 12 Ultimate and 64-bit operation, but does not include XeSS (XMX) support.
In Geekbench 6, the system scores 2331 in the single-core test and 11009 in the multi-core test. PassMark results show a single-thread score of 3738 and an overall CPU mark of 28497, while the GPU-focused PassMark G3D benchmark returns a score of 17710.
The laptop's wired port selection includes two USB 3.2 Gen 2 Type-C ports, two USB 3.2 Gen 2 Type-A ports, one HDMI 2.1 output, and one RJ45 Ethernet port; there are no Thunderbolt 3 or 4 ports, no USB 4 ports, no DisplayPort or mini DisplayPort outputs, and no VGA connector. An external memory slot is also present. On the wireless side, the machine supports Wi-Fi 6E (802.11ax) along with Wi-Fi 6, Wi-Fi 5, and Wi-Fi 4, as well as Bluetooth 5.3 and AirPlay.
The laptop is equipped with an 80 Wh battery and 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.
Audio output is handled by stereo speakers with a 3.5 mm headset jack, while two built-in microphones and a front camera cover communication needs; Dolby Atmos and S/PDIF output are not included. On the graphics feature side, the laptop supports ray tracing and DLSS, though it lacks XeSS. There is no fingerprint scanner, 3D facial recognition, or voice command support for biometric or hands-free interaction. The device also omits motion and positioning sensors such as a gyroscope, accelerometer, GPS, and compass, and it does not include an optical disc drive or a stylus.
The CPU is a laptop-class processor with a clock multiplier of 38, a TDP of 115W, a maximum operating temperature of 100 °C, and a cache hierarchy consisting of 512 KB L1, 8 MB L2 (1 MB/core), and 16 MB L3 (2 MB/core). It supports the NX bit, double precision floating point, and instruction sets including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2, but does not use big.LITTLE technology and has a locked multiplier. Integrated graphics are present alongside the discrete GPU, which is built on the Ada Lovelace architecture and comprises 3072 shading units, 96 texture mapping units, 48 ROPs, 12 execution units, and 18,900 million transistors; it does not carry LHR restrictions. The GPU operates with a memory speed of 2000 MHz over a 128-bit bus, delivering an effective memory speed of 16,000 MHz and a maximum bandwidth of 256 GB/s, while the system RAM supports up to 7500 MHz across 2 memory channels and is ECC-compatible. Graphics API support covers OpenCL 3 and OpenGL 4.6, with stereoscopic 3D and multi-display technology both supported. The PassMark DirectCompute result stands at 6787 and the overclocked PassMark score reaches 29,732.
