Lenovo Legion Slim 5 16AHP9 16" AMD Ryzen 7 8845HS 3.8GHz / Nvidia GeForce RTX 4050 Laptop / 16GB RAM / 1TB SSD

Manufacturer: Lenovo

The Lenovo Legion Slim 5 16AHP9 is a 16″ gaming laptop built around AMD's Ryzen 7 8845HS processor and an Nvidia GeForce RTX 4050 discrete GPU. Weighing 2300 g and measuring just 19 mm thick, it strikes a balance between portability and gaming capability. The machine ships with 16GB of DDR5 RAM running at 5600 MHz, a 1TB NVMe SSD, and supports up to 64GB of memory across its two slots, giving it room to grow over time.

The 16″ IPS LCD panel runs at a 2560 x 1600 resolution with a 165Hz refresh rate, 188 ppi pixel density, 300 nits of typical brightness, and an anti-reflection coating. On the GPU side, the RTX 4050 delivers 12.13 TFLOPS of floating-point performance, 6GB of GDDR6 VRAM on a 96-bit bus, and support for DirectX 12 Ultimate, ray tracing, and DLSS. Connectivity includes two USB 3.2 Gen 2 Type-C ports, two USB 3.2 Gen 2 Type-A ports, HDMI 2.1, Wi-Fi 6E, Bluetooth 5.3, and a single RJ45 Ethernet port, all backed by an 80 Wh battery and a 2-year warranty.

Pros
  • The 16-inch IPS display runs at 2560 x 1600 resolution with a 165Hz refresh rate and an anti-reflection coating, making it well-suited for both gaming and detailed visual work
  • The CPU supports up to 5.1 GHz turbo clock speed across 8 cores and 16 threads, and RAM is expandable to 64GB across two slots, offering meaningful headroom for future upgrades
  • The GPU delivers 12.13 TFLOPS of floating-point performance with support for ray tracing and DLSS, adding flexibility for graphically demanding workloads
  • At 19mm thick and 2300g, the chassis is relatively slim for an active-cooled gaming laptop, making it reasonably portable
  • Connectivity is comprehensive, with two USB 3.2 Gen 2 Type-C ports, two USB 3.2 Gen 2 Type-A ports, HDMI 2.1, Wi-Fi 6E, Bluetooth 5.3, an RJ45 port, and an external memory slot
  • The 80 Wh battery includes sleep-and-charge USB support, allowing peripheral charging without fully powering on the system
Cons
  • With only 300 nits of typical brightness, the display may struggle in bright ambient lighting conditions
  • The GPU uses a 96-bit memory bus, which is narrower than configurations found on higher-tier discrete graphics solutions, potentially limiting memory throughput in demanding scenarios
  • There is no fingerprint scanner or 3D facial recognition, leaving the backlit keyboard as the primary physical interaction method with no biometric login option
  • Dolby Atmos is not supported, limiting the audio experience to standard stereo output
  • No Thunderbolt 3 or Thunderbolt 4 ports are present, which restricts compatibility with high-bandwidth external docks and certain external GPU enclosures
  • The laptop is not weather-sealed, offering no protection against moisture or splashes
Who is this for?

This laptop is a solid fit for users who want a capable gaming machine that can also handle demanding everyday workloads. The 165Hz IPS display at 2560 x 1600 resolution combined with ray tracing and DLSS support makes it a practical choice for gamers who value visual clarity and smooth frame delivery. The 8-core, 16-thread CPU with a 5.1 GHz turbo clock, paired with DDR5 RAM expandable to 64GB, suits content creators and multitaskers who need sustained processing headroom. Its relatively slim 19mm profile and 2300g weight also make it reasonable for students or professionals who need to carry a gaming-capable machine between locations regularly.

Who is this NOT for?

Users who require top-tier graphics output may find the RTX 4050's 96-bit memory bus and 6GB of GDDR6 VRAM limiting when running the most graphically intensive titles at the display's native resolution with all settings maximized. The 300-nit brightness ceiling makes this a poor fit for anyone who frequently works in brightly lit or outdoor environments, where screen visibility would be noticeably compromised. Additionally, professionals who rely on high-bandwidth external peripherals or docking solutions will be constrained by the absence of Thunderbolt 3 or Thunderbolt 4 ports, and those needing biometric security will find the lack of a fingerprint scanner or facial recognition unsuitable for their workflow.
