Lenovo Legion Slim 5 16IRH8 16" Intel Core i7-13700H 2.4GHz / Nvidia GeForce RTX 4070 Laptop / 32GB RAM / 1TB SSD

Manufacturer: Lenovo

The Lenovo Legion Slim 5 16IRH8 is a 16″ gaming laptop built around Intel's Core i7-13700H processor and Nvidia's GeForce RTX 4070 Laptop graphics. Weighing 2,400 g and measuring just 19 mm thin, it balances a relatively compact form factor with hardware suited for demanding workloads. The machine ships with 32GB of DDR5 RAM running at 5,200 MHz alongside a 1TB NVMe SSD, and its backlit keyboard sits within a chassis that supports up to four external displays simultaneously.

The display is a 16″ IPS LCD panel running at a native resolution of 2,560 × 1,600 px, delivering a pixel density of 188 ppi and a 165Hz refresh rate, with an anti-reflection coating and a typical brightness of 300 nits. On the graphics side, the RTX 4070 Laptop GPU is built on a 4 nm Ada Lovelace architecture with 4,608 shading units, 8GB of GDDR6X VRAM on a 128-bit bus, and a floating-point throughput of 20.04 TFLOPS, while also supporting 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, an RJ45 port, Wi-Fi 6E, and Bluetooth 5.3, rounded out by a 60 Wh battery and a 3.5 mm audio jack.

Pros
  • The 165Hz refresh rate on the 2560x1600 IPS display provides smooth visuals at a higher-than-standard resolution for a 16-inch screen
  • 32GB of DDR5 RAM running at 5200 MHz across two slots supports demanding multitasking workloads without immediate memory constraints
  • The NVMe SSD on PCIe 4.0 ensures fast storage access for both system operations and large file handling
  • GPU support for ray tracing and DLSS expands rendering options for compatible applications
  • Wi-Fi 6E support alongside a dedicated RJ45 port gives flexibility between wired and high-speed wireless networking
  • At 19 mm thick and 2400 g, the chassis maintains a relatively slim profile for a gaming laptop with active cooling
Cons
  • The 60 Wh battery is modest for a 16-inch gaming laptop with a 115W TDP processor, likely limiting unplugged usage under load
  • No Thunderbolt 4 or USB 4 ports are present, restricting high-bandwidth peripheral and external display options
  • The display is capped at 300 nits typical brightness, which may be limiting in brighter environments
  • There is no fingerprint scanner or facial recognition, so biometric login is unavailable
  • Only one HDMI port and no DisplayPort outputs limit direct wired display connectivity options
  • The maximum supported RAM is 32GB with no room for future expansion beyond the current configuration
Who is this for?

This laptop is well-suited to users who need a capable machine for graphically demanding gaming and creative workloads, given its RTX 4070 GPU with ray tracing and DLSS support, 20.04 TFLOPS of floating-point performance, and a 2560x1600 IPS display running at 165Hz. The 32GB of DDR5 RAM paired with a PCIe 4.0 NVMe SSD also makes it a reasonable fit for content creators or developers handling large files and memory-intensive applications. Those who frequently connect external peripherals or monitors will appreciate the multi-display support for up to four screens, Wi-Fi 6E, and the combination of USB 3.2 Gen 2 ports alongside an HDMI 2.1 output.

Who is this NOT for?

Users who need a laptop for extended use away from a power outlet will likely find the 60 Wh battery constraining, particularly given the 115W CPU TDP and the demands of the discrete GPU under load. The absence of Thunderbolt 4 or USB 4 ports makes this a poor fit for professionals who rely on high-bandwidth external storage or advanced docking solutions. Additionally, users working frequently in bright outdoor environments may find the 300-nit typical brightness insufficient for comfortable screen visibility, and those requiring biometric login through a fingerprint scanner or facial recognition will find no such options available on this machine.

Final Verdict

The Lenovo Legion Slim 5 16IRH8 is a focused gaming laptop that brings together a capable hardware stack — including an RTX 4070 GPU, 32GB of DDR5 RAM, and a 165Hz 2560x1600 IPS display — within a form factor that remains notably slim at 19 mm for its class. Its Ada Lovelace GPU with ray tracing and DLSS support, combined with fast PCIe 4.0 NVMe storage and Wi-Fi 6E connectivity, makes it a well-rounded machine for users whose primary focus is gaming or GPU-accelerated workloads at a desk or in a fixed setup. That said, the modest 60 Wh battery and the absence of Thunderbolt 4 signal that this machine is optimized for performance rather than versatility or untethered use. For users who can work within those constraints, it represents a technically cohesive package that delivers meaningfully on its gaming-oriented brief.
