The Lenovo Legion Slim 5 16IRH8 is a gaming laptop with a footprint of 359 mm wide by 260 mm deep and a 19 mm thickness, giving it a relatively lean profile for its category, with a total volume of 1,773.46 cm³ and a weight of 2,400 g. It includes a backlit keyboard for low-light use and relies on active cooling rather than a fanless design. The chassis is not weather-sealed, so it offers no splash protection, and the machine comes with a 1-year warranty.
The laptop features a 16″ LED-backlit IPS LCD panel with a 2560x1600 pixel resolution at 188 ppi, offering noticeably sharper detail than standard 1080p screens at this size. It runs at a 165Hz refresh rate and reaches a typical brightness of 300 nits, with an anti-reflection coating to help manage glare in varied lighting conditions. Touch input is not supported, and the system can drive up to four connected displays simultaneously.
The CPU runs four cores at 2.6 GHz and eight cores at 1.9 GHz across 16 threads, with multithreading enabled and a turbo clock reaching 4.7 GHz; it is built on a 5 nm process and is fully 64-bit compatible. Memory consists of 16GB of DDR5 RAM at 5200 MHz across two slots, expandable to a maximum of 32GB, while a 1TB PCIe 4.0 NVMe SSD handles storage. The GPU carries 8GB of GDDR6 VRAM with a base clock of 1545 MHz boosting to 2370 MHz, producing 14.56 TFLOPS of floating-point output alongside a texture rate of 227.52 GTexels/s and a pixel rate of 113.76 GPixel/s, with DirectX 12 Ultimate support; XeSS is not available on this configuration.
In standardized CPU testing, the system achieved an overall PassMark score of 21,330 alongside a single-thread result of 3,393, giving a concrete indication of both multi-core and per-core processing throughput. On the graphics side, the PassMark G3D result of 17,710 reflects the GPU's rendering capability under benchmark conditions.
The laptop's port layout includes two USB 3.2 Gen 2 Type-C ports and two USB 3.2 Gen 2 Type-A ports, though there are no Thunderbolt 3 or 4 ports and no USB 4 connections of any speed. Video output is provided through a single HDMI 2.1 port, with no DisplayPort, mini DisplayPort, or VGA connector present. Wired networking is available via one RJ45 port, and wireless connectivity covers Wi-Fi 6E, Wi-Fi 6, Wi-Fi 5, and Wi-Fi 4 standards alongside Bluetooth 5.3. The machine also includes an external memory card slot and supports AirPlay.
The laptop is equipped with an 80 Wh battery and supports 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 for charging.
Audio output is handled by stereo speakers with a 3.5 mm headset jack available, though Dolby Atmos and S/PDIF output are not included. A front camera is present, while biometric security options such as a fingerprint scanner and 3D facial recognition are both absent, and voice commands are not supported. On the gaming side, the GPU supports both ray tracing and DLSS, extending its capabilities for compatible titles. The machine has no motion or location sensors — there is no gyroscope, accelerometer, compass, or GPS — and it ships without a stylus or an optical disc drive.
The laptop-class CPU carries a clock multiplier of 26, a 115W TDP, a maximum operating temperature of 100 °C, and uses big.LITTLE technology; the multiplier is locked, and the chip includes 10 MB of L2 cache, 18 MB of L3 cache, NX bit support, Double Precision Floating Point capability, and instruction set coverage spanning SSE 4.1, SSE 4.2, AVX, AES, FMA3, F16C, and MMX. Integrated graphics are provided by the Iris Xe Graphics 80EU with 80 execution units, sitting alongside the discrete GPU which is built on the Ada Lovelace architecture and contains 18,900 million transistors across 3,072 shading units, 96 TMUs, and 48 ROPs, with GPU memory running at 2,000 MHz, an effective speed of 16,000 MHz over a 128-bit bus, and a maximum memory bandwidth of 256 GB/s. System RAM runs across two channels at up to 5,200 MHz, ECC memory is supported, and compute API support covers OpenCL 3 and OpenGL 4.6, with stereoscopic 3D and multi-display output both enabled. The PassMark DirectCompute result is 6,787 and the overclocked PassMark score reaches 23,897, while LHR is not present on this GPU.
