Lenovo LOQ 15IRX9 15.6" Intel Core i5-13450HX 2.4GHz / Nvidia GeForce RTX 4050 Laptop / 8GB RAM / 512GB 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 card. Weighing 2,380 g and measuring just 21 mm thick, it balances a reasonably compact form factor with dedicated gaming hardware. The machine ships with 8GB of DDR5 RAM and a 512GB NVMe SSD, with support for up to 32GB across its two memory slots. A backlit keyboard and stereo speakers round out the day-to-day usability features.

The IPS panel delivers a 1920 x 1080 resolution at 141 ppi with a 144Hz refresh rate and 300 nits of typical brightness, backed by an anti-reflection coating. On the graphics side, the RTX 4050 brings 6GB of GDDR6 VRAM across a 96-bit bus, 2,560 shading units, and 12.13 TFLOPS of floating-point performance, with support for DirectX 12 Ultimate, ray tracing, and DLSS. Connectivity includes Wi-Fi 6, Bluetooth 5.2, one USB 3.2 Gen 2 Type-C port, three USB 3.2 Gen 1 Type-A ports, an HDMI 2.1 output, and a single RJ45 Ethernet port. The 60 Wh battery supports sleep-and-charge functionality.

Pros
  • The 144Hz IPS display with anti-reflection coating and 1920x1080 resolution suits fast-paced gaming without glare interference
  • Ray tracing and DLSS support are present, enabling more advanced rendering options in compatible games
  • The NVMe SSD with PCIe 4 delivers fast storage access, and the two memory slots allow expansion up to 32GB of DDR5 RAM
  • Four simultaneous display outputs offer flexible multi-screen setups
  • Wi-Fi 6 support alongside a wired RJ45 port provides both fast wireless and stable ethernet connectivity
  • Sleep-and-charge USB functionality allows peripheral charging even when the laptop is off or sleeping
Cons
  • Only 8GB of RAM is included at launch, which may require an upgrade for memory-intensive workloads
  • The 60 Wh battery is modest for a gaming laptop with a 115W TDP processor, likely limiting unplugged use
  • The 96-bit memory bus width on the GPU is narrower than wider-bus alternatives in the same GPU tier, affecting memory throughput
  • No fingerprint scanner or facial recognition is available, leaving the laptop without biometric login options
  • There is no external memory card slot, limiting quick file transfers from cameras or other card-based devices
  • No DisplayPort output is available, restricting direct monitor connections to HDMI only
Who is this for?

This laptop is a solid fit for users who primarily engage in gaming at 1080p, where the 144Hz IPS display, RTX 4050 with ray tracing and DLSS support, and 12.13 TFLOPS of GPU performance combine to handle modern titles at that resolution. The PCIe 4 NVMe SSD, DDR5 RAM, and 10-core CPU with multithreading also make it a capable machine for content creation and media work that benefits from fast storage and multi-threaded processing. Users who need flexible connectivity at a desk — with Wi-Fi 6, a wired Ethernet port, HDMI 2.1, and support for up to four displays — will find the port selection practical for a semi-permanent workstation setup.

Who is this NOT for?

Users who need extended unplugged usage will likely find the 60 Wh battery insufficient given the 115W CPU TDP, making this a poor fit for work in environments without reliable power access. The 96-bit memory bus and 8GB of RAM out of the box also mean it is not well-suited for highly demanding AAA gaming at higher resolutions or memory-intensive professional workflows such as large dataset processing or heavy virtual machine use without a RAM upgrade. Additionally, those who require biometric security features like fingerprint scanning or facial recognition for quick and secure authentication will find this machine lacking in that area.

Final Verdict

The Lenovo LOQ 15IRX9 is a gaming laptop that delivers a coherent set of specifications for users focused on 1080p gaming and everyday productivity. Its RTX 4050 GPU with Ada Lovelace architecture, combined with 144Hz IPS display, DLSS, and ray tracing support, forms a capable foundation for modern gaming workloads, while the PCIe 4 NVMe SSD and DDR5 memory keep the system feeling responsive. That said, the 8GB of RAM at base configuration and the modest 60 Wh battery are real limitations that will surface for users pushing the hardware hard or working away from a power outlet. For those who can work within those constraints — primarily desk-bound gamers or light creative users — the LOQ 15IRX9 presents a well-rounded configuration that covers the essentials without unnecessary compromise.
