Lenovo Legion Slim 5 16ARP9 16" AMD Ryzen 7 7435HS 3.1GHz / Nvidia GeForce RTX 4070 Laptop / 16GB RAM / 1TB SSD

Manufacturer: Lenovo

The Lenovo Legion Slim 5 16ARP9 is a gaming laptop built around the AMD Ryzen 7 7435HS processor and an Nvidia GeForce RTX 4070 Laptop GPU, housed in a 19 mm thin chassis weighing 2.3 kg. Its 2560 x 1600 px IPS display runs at 165Hz with an anti-reflection coating, making it a capable screen for both gaming and general use across a 16″ panel at 188 ppi.

Under the hood, the system pairs 16 GB of DDR5 RAM at 4800 MHz — expandable up to 64 GB across two slots — with a 1 TB NVMe SSD. The RTX 4070 Laptop GPU brings 8 GB of GDDR6X VRAM, ray tracing support, and DLSS, with 20.04 TFLOPS of floating-point performance and a GPU turbo clock of 2175 MHz. Connectivity covers Wi-Fi 6E, Bluetooth 5.3, one HDMI 2.1 port, an RJ45 Ethernet port, two USB 3.2 Gen 2 Type-A ports, one USB 3.2 Gen 2 Type-C port, and an external memory slot, backed by an 80 Wh battery and a 2-year warranty.

Pros
  • The RTX 4070 Laptop GPU with 20.04 TFLOPS, ray tracing support, and DLSS makes this a capable machine for modern gaming workloads
  • The 165Hz 2560 x 1600 px IPS display with anti-reflection coating is well-suited to gaming and fast-paced visual content at a sharp 188 ppi
  • Wi-Fi 6E, an RJ45 Ethernet port, and Bluetooth 5.3 together provide flexible and fast wired and wireless networking options
  • At 19 mm thick and 2300 g, the chassis is relatively slim and manageable for a gaming laptop with discrete graphics
  • The 1 TB NVMe SSD over PCIe 4 offers fast storage access, and RAM is expandable up to 64 GB across two slots
  • Sleep-and-charge USB support allows connected devices to be charged even when the laptop is not in active use
Cons
  • There are no Thunderbolt ports (3 or 4) and no USB 4 support, which limits high-speed peripheral and external display options
  • No fingerprint scanner or facial recognition is available, so biometric login is not supported
  • The 80 Wh battery, while reasonable in capacity, is paired with a 115W TDP CPU, which is likely to result in limited unplugged gaming or heavy workload runtime
  • The display brightness is rated at only 350 nits, which may be insufficient in brightly lit environments
  • No DisplayPort output is available, limiting direct high-refresh external monitor connections to HDMI 2.1 only
  • Dolby Atmos is not supported, reducing the audio experience for users who rely on spatial sound formats
Who is this for?

This laptop is well-matched for gamers and power users who want a capable discrete GPU in a relatively slim chassis — the RTX 4070 Laptop GPU with ray tracing and DLSS support handles demanding titles, while the 165Hz 2560 x 1600 px display delivers the refresh rate and resolution needed to take full advantage of that GPU output. The Wi-Fi 6E connectivity, RJ45 Ethernet port, and expandable RAM up to 64 GB also make it a practical fit for users who split their time between gaming and memory-intensive workloads like content creation or data processing.

Who is this NOT for?

Users who frequently work in bright environments may find the 350-nit display limiting, as outdoor or high-ambient-light use will be challenging. Those who rely on Thunderbolt for fast external storage or high-bandwidth peripherals will be disappointed by the complete absence of Thunderbolt 3 or 4 ports. Additionally, users who need biometric login — whether via fingerprint or facial recognition — will need to use password-based authentication instead, and anyone expecting extended unplugged sessions under heavy load should note that an 80 Wh battery paired with a 115W TDP processor is unlikely to sustain long runtimes away from an outlet.
