The Lenovo Legion Slim 5 16ARP9 is classified as a gaming laptop with a physical footprint of 359 mm wide by 260 mm deep and a thickness of just 19 mm, giving it a relatively compact form for its category. It displaces a volume of 1773.46 cm³ and tips the scales at 2300 g. The chassis does not carry a weather-sealed or splashproof rating, and it does not use a fanless cooling design. On the usability side, the keyboard is backlit, and the laptop is covered by a 2-year warranty.
The laptop features a 16-inch IPS LCD panel with LED backlighting, rendering images at 2560 x 1600 px for a pixel density of 188 ppi. With a 165Hz refresh rate, the screen is well-suited for fast-moving content, and typical brightness is rated at 350 nits. An anti-reflection coating is present to help reduce glare, while touch input is not supported.
The system is powered by an 8-core, 16-thread CPU running at a base speed of 8 x 3.1 GHz and a turbo clock of 4.5 GHz, built on a 5 nm process with 64-bit and multithreading support. It comes with 16GB of DDR5 RAM at 4800 MHz across two memory slots, expandable up to 64GB, paired with a 1024GB NVMe SSD using PCIe 4.0. On the graphics side, the GPU carries 8GB of GDDR6 VRAM, a base clock of 1545 MHz boosting up 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, with full support for DirectX 12 Ultimate; XeSS is not supported.
In PassMark testing, the system achieves an overall CPU score of 23,380 and a single-thread score of 3,168, reflecting the processor's multi-core and per-core capabilities respectively. The GPU records a PassMark G3D score of 17,710, representing its 3D graphics rendering performance.
The laptop offers a practical spread of wired and wireless connectivity options. USB ports include one USB 3.2 Gen 2 Type-C and two USB 3.2 Gen 2 Type-A ports, while Thunderbolt 3 and 4, USB 4, and additional Gen 1 ports are absent. Video output is handled by a single HDMI 2.1 port, with no DisplayPort or VGA connectors present. Wired networking is covered by one RJ45 port, and wireless connectivity spans Wi-Fi 6E (802.11ax) down through Wi-Fi 4 (802.11n), complemented by Bluetooth 5.3. An external memory slot is also available, and AirPlay is supported.
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. A MagSafe power adapter is not supported.
On the audio side, the laptop includes stereo speakers, a 3.5 mm headset jack, and two microphones, though Dolby Atmos and an S/PDIF output are not present. A front camera is built in, while fingerprint scanning, 3D facial recognition, and a stylus are not included. Graphics features cover ray tracing and DLSS support, making the GPU capable of handling both effects in compatible applications. Sensor and navigation hardware — including a gyroscope, accelerometer, compass, and GPS — are absent, and there is no optical disc drive.
The GPU is based on the Ada Lovelace architecture and packs 3,072 shading units, 96 texture mapping units, and 48 render output units, with a memory bus width of 128-bit, a GPU memory speed of 2,000 MHz, an effective memory speed of 16,000 MHz, and a maximum memory bandwidth of 256 GB/s; it does not feature LHR. The GPU also supports stereoscopic 3D, multi-display output, double precision floating point, ECC memory, OpenCL 3, and OpenGL 4.6, recording a PassMark DirectCompute score of 6,787. On the CPU side, the processor carries a clock multiplier of 31 and a TDP of 115 W, with a maximum operating temperature of 95 °C, an NX bit, and support for instruction sets including MMX, F16C, FMA3, AES, AVX, AVX2, SSE 4.1, and SSE 4.2; it does not use big.LITTLE technology and the multiplier is locked. The cache hierarchy consists of 512 KB L1, 4 MB L2 at 0.5 MB per core, and 16 MB L3 at 2 MB per core, with two memory channels supporting RAM up to 4,800 MHz and a transistor count of 18,900 million. An overclocked PassMark result of 25,238 is also recorded, and no integrated graphics are present.
