Lenovo LOQ 15IRX9 15.6" Intel Core i5-13450HX 2.4GHz / Nvidia GeForce RTX 4050 Laptop / 16GB RAM / 1TB SSD

Manufacturer: Lenovo

The Lenovo LOQ 15IRX9 is a 15.6″ gaming laptop built around Intel's Core i5-13450HX processor and Nvidia's GeForce RTX 4050 graphics. Weighing 2,380 g and measuring just 21 mm thick, it occupies a relatively compact footprint for its class. The machine ships with 16GB of DDR5 RAM across two slots — expandable to 32GB — alongside a 1TB NVMe SSD, and runs on a backlit keyboard with stereo speakers and a dual-microphone setup as standard.

On the display side, the 1920 x 1080 IPS panel delivers 141 ppi and a 144Hz refresh rate at 300 nits typical brightness, with anti-reflection coating included. The RTX 4050 GPU carries 6GB of GDDR6 VRAM on a 96-bit memory bus, reaches up to 2370 MHz in boost, and posts 12.13 TFLOPS of floating-point performance with full DirectX 12 Ultimate and ray tracing support. Connectivity includes one USB 3.2 Gen 2 Type-C port, three USB 3.2 Gen 1 Type-A ports, an HDMI 2.1 output, an RJ45 Ethernet jack, Wi-Fi 6, and Bluetooth 5.2, all backed by a 60 Wh battery and a two-year warranty.

Pros
  • The 144Hz IPS display with anti-reflection coating makes for smoother on-screen motion and reduced glare during extended gaming sessions
  • DLSS and ray tracing support allows the GPU to handle more demanding rendering workloads
  • The NVMe SSD on PCIe 4.0 ensures fast storage read and write operations for loading times and file transfers
  • Wi-Fi 6 support alongside a wired RJ45 port gives flexibility for both high-speed wireless and stable cabled network connections
  • The two-slot memory configuration supports upgrades up to 32GB, providing room to expand beyond the default 16GB
  • A backlit keyboard and stereo speakers with a 3.5 mm audio jack cover the essentials for both low-light gaming and audio output
Cons
  • The 60 Wh battery is relatively modest for a gaming laptop with a 115W TDP processor, suggesting limited unplugged runtime under load
  • At 2,380 g and 21 mm thick, the chassis is not particularly suited for frequent travel or lightweight portability
  • The 96-bit memory bus width on the GPU is narrower than higher-tier configurations, which constrains overall memory bandwidth headroom
  • There is no fingerprint scanner or 3D facial recognition, so biometric login is not available
  • No DisplayPort or Thunderbolt output is present, limiting options for connecting high-refresh-rate or professional external monitors
  • The absence of an external memory card slot reduces quick media transfer options for photographers or videographers
Who is this for?

This laptop is a solid fit for users who want to game at home on a 1080p 144Hz display with hardware-accelerated features like ray tracing and DLSS enabled. The 10-core CPU with multithreading support and 16GB of DDR5 RAM also make it capable for content creators or students running moderately demanding software, while the 1TB NVMe SSD keeps load times short across both games and productivity applications. The RJ45 Ethernet port and Wi-Fi 6 support make it equally well-suited for users who need a reliable and flexible network connection for online gaming or remote work.

Who is this NOT for?

Users who need to work frequently on the move will find the 2,380 g weight combined with the 60 Wh battery a limiting combination, as the chassis is heavy to carry and the battery is unlikely to sustain high-load sessions for long away from a power outlet. The 96-bit memory bus and 6GB of GDDR6 VRAM are not well-suited for high-resolution creative workloads such as 4K video editing or rendering that demand substantial VRAM and bandwidth headroom. Additionally, the absence of Thunderbolt ports and DisplayPort outputs makes this a poor match for professionals who rely on high-bandwidth external displays or docking station ecosystems.

Final Verdict

The Lenovo LOQ 15IRX9 presents a well-rounded specification sheet for a home-based gaming laptop, anchored by its 144Hz IPS display with ray tracing and DLSS support that enables a genuinely capable gaming experience at 1080p. The DDR5 RAM configuration, PCIe 4.0 NVMe storage, and Wi-Fi 6 connectivity add up to a package that handles both gaming and everyday computing tasks without obvious bottlenecks in those areas. That said, the 60 Wh battery, 2,380 g chassis, and narrower GPU memory bus signal that this machine is purpose-built for stationary use rather than versatility on the move. For users whose primary intent is desktop-replacement gaming within a fixed environment, the LOQ 15IRX9 covers the essentials competently; those needing portability, Thunderbolt connectivity, or headroom for high-resolution creative work will need to look elsewhere.
