Lenovo Legion Slim 5 16ARP9 16" AMD Ryzen 7 7735HS 3.2GHz / Nvidia GeForce RTX 4070 Laptop / 16GB RAM / 1TB SSD

Manufacturer: Lenovo

The Lenovo Legion Slim 5 16ARP9 is a 16″ gaming laptop built around AMD's Ryzen 7 7735HS processor and Nvidia's GeForce RTX 4070 Laptop GPU. Weighing 2300 g and measuring just 19 mm thick, it sits in a relatively compact form factor for its class. The machine ships with 16GB of DDR5 RAM and a 1TB NVMe SSD, while the memory configuration supports expansion up to 64GB across two slots.

The display runs at a resolution of 2560 x 1600 px on a 16″ IPS LCD panel with a 165Hz refresh rate, 188 ppi pixel density, 350 nits of typical brightness, and an anti-reflection coating. On the graphics side, the RTX 4070 Laptop GPU delivers 20.04 TFLOPS of floating-point performance, 8GB of GDDR6X VRAM on a 128-bit bus, and support for ray tracing and DLSS. Connectivity includes USB 3.2 Gen 2 ports in both Type-A and Type-C form, HDMI 2.1, Wi-Fi 6E, Bluetooth 5.3, and a single RJ45 port, all backed by an 80 Wh battery.

Pros
  • The 16″ IPS display runs at 165Hz with a 2560x1600 resolution and includes an anti-reflection coating, making it well-suited for extended gaming or content work sessions
  • The RTX 4070 Laptop GPU supports both ray tracing and DLSS, and delivers 20.04 TFLOPS of floating-point performance with 8GB of GDDR6X VRAM
  • At 19 mm thick and 2300 g, the chassis is relatively slim for a gaming laptop with active cooling
  • Wi-Fi 6E support alongside Bluetooth 5.3 and a wired RJ45 port provides a flexible range of networking options
  • The system supports up to 64GB of DDR5 RAM across two slots, offering meaningful headroom for future memory upgrades
  • Sleep-and-charge USB ports allow connected devices to be charged even when the laptop is powered down
Cons
  • Only a single USB 3.2 Gen 2 Type-C port is available, with no Thunderbolt 3 or 4 and no USB 4 support
  • There is no fingerprint scanner or 3D facial recognition, leaving the device without biometric authentication options
  • The panel brightness is rated at 350 nits, which may be limiting in brightly lit environments
  • The warranty period covers only one year
  • No DisplayPort output is included, limiting wired display connectivity options to the single HDMI 2.1 port
  • The laptop is not weather-sealed, offering no protection against splashes or moisture
Who is this for?

This laptop is a solid fit for gamers and creative users who want a capable machine without a bulky chassis — at 19 mm thick and 2300 g, it strikes a reasonable balance between portability and capability. The 165Hz 2560x1600 IPS display with an anti-reflection coating makes it well-suited for gaming sessions and visual work alike, while the RTX 4070 Laptop GPU with ray tracing and DLSS support will appeal to those who want smooth frame rates in graphically demanding titles. Users who multitask across memory-heavy applications will appreciate the two-slot configuration that supports up to 64GB of DDR5 RAM, and the 1TB NVMe SSD provides ample fast storage for large game libraries or media projects.

Who is this NOT for?

Users who rely on advanced port connectivity will find the selection limiting, as there is no Thunderbolt, no USB 4, and no DisplayPort output — making it a poor fit for those who regularly connect multiple external displays or high-speed peripherals. The lack of biometric login options such as a fingerprint scanner or facial recognition may be a drawback for business users or anyone who prioritizes fast, secure authentication. Additionally, those who work frequently in bright outdoor environments may find the 350-nit brightness insufficient, and users requiring weather resistance or ruggedized build quality will need to look elsewhere given the absence of any splash-proofing.
