Lenovo LOQ 15IAX9 15.6" Intel Core i5-12450HX 2.4GHz / Nvidia GeForce RTX 4050 Laptop / 24GB RAM / 1TB SSD

Manufacturer: Lenovo

The Lenovo LOQ 15IAX9 is a 15.6″ gaming laptop built around Intel's Core i5-12450HX processor and an Nvidia GeForce RTX 4050 graphics card. It ships with 24GB of DDR5 RAM running at 4800 MHz alongside a 1TB NVMe SSD, giving it a solid foundation for both gaming sessions and everyday computing tasks. The chassis weighs 2380 g, measures 21 mm thick, and includes a backlit keyboard, making it a reasonably portable machine for its class. A two-year warranty is included.

The display runs at 1920 x 1080 resolution across the 15.6″ IPS panel, delivering a pixel density of 141 ppi, a 300-nit typical brightness, and a 144Hz refresh rate with an anti-reflection coating. On the graphics side, the RTX 4050 is built on Nvidia's Ada Lovelace architecture at 4 nm, carries 6GB of GDDR6 VRAM over a 96-bit bus, and reaches a floating-point throughput of 12.13 TFLOPS, with support for ray tracing and DLSS. Connectivity includes one USB 3.2 Gen 2 Type-C port, three USB 3.2 Gen 1 Type-A ports, HDMI 2.1, an RJ45 Ethernet jack, Wi-Fi 6, and Bluetooth 5.2. The 60 Wh battery rounds out the specification set.

Pros
  • The 144Hz IPS display with an anti-reflection coating makes it well suited for fast-paced gaming without excessive glare
  • Support for both ray tracing and DLSS gives the GPU access to modern rendering techniques during compatible games
  • 24GB of DDR5 RAM across two slots provides headroom for memory-intensive tasks, with the option to expand up to 32GB
  • The 1TB NVMe SSD on a PCIe 4 interface ensures fast storage access for large game installs and application loads
  • A full set of wireless standards including Wi-Fi 6 and Bluetooth 5.2 keeps the machine current for wireless peripherals and networking
  • The inclusion of HDMI 2.1 and support for up to four displays adds flexibility for multi-monitor setups
Cons
  • The 60 Wh battery is modest for a gaming laptop, particularly given the 115W CPU TDP
  • At 2380 g and 21 mm thick, the chassis is on the heavier and bulkier side for regular portability
  • There is no fingerprint scanner or 3D facial recognition, leaving the machine without biometric login options
  • The 6GB GDDR6 VRAM over a 96-bit memory bus is relatively narrow for higher-resolution or more demanding gaming scenarios
  • A single USB 3.2 Gen 2 port is the only high-speed data transfer option, with no Thunderbolt or USB 4 connectivity available
  • The display brightness is rated at only 300 nits, which may limit visibility in bright ambient lighting conditions
Who is this for?

This laptop is a solid fit for users who spend significant time on gaming at 1080p, where the RTX 4050 with ray tracing and DLSS support, combined with the 144Hz IPS display, delivers a smooth and visually capable experience. The 24GB of DDR5 RAM and 1TB NVMe SSD also make it practical for content creators or students who run memory-hungry applications alongside large project files. Those who need flexible multi-display setups will appreciate the HDMI 2.1 output and support for up to four connected screens, while Wi-Fi 6 and Bluetooth 5.2 keep the connectivity side current for home or office environments.

Who is this NOT for?

Users who prioritize portability will find the 2380 g weight and 21 mm thickness inconvenient for frequent travel or commuting. The 60 Wh battery is modest relative to the system's 115W CPU TDP, meaning those who need extended unplugged sessions will likely face limitations. The 6GB GDDR6 VRAM over a narrow 96-bit bus is also insufficient for users targeting higher-resolution gaming or GPU-accelerated workloads that demand greater memory capacity and bandwidth. Additionally, the absence of Thunderbolt or USB 4 ports makes this a poor fit for professionals who rely on high-speed external docking stations or fast external storage solutions.

Final Verdict

The Lenovo LOQ 15IAX9 is a well-defined entry in the gaming laptop segment, built around a clear set of priorities: a capable RTX 4050 GPU with ray tracing and DLSS support, a generous 24GB of DDR5 RAM, fast NVMe storage, and a 144Hz IPS display that ties the hardware together for a coherent 1080p gaming experience. Its connectivity through HDMI 2.1 and Wi-Fi 6 reflects a thoughtful approach to modern standards, even if the absence of Thunderbolt and the narrowness of the GPU's memory bus signal that this machine has defined boundaries. Users who stay within those boundaries — primarily 1080p gaming and everyday productivity — will find it a focused and competent machine, while those chasing demanding workloads or maximum portability may find its thermal envelope and chassis weight working against them. Taken on its own terms, the LOQ 15IAX9 is a purposeful gaming laptop that delivers meaningfully in its intended use cases without overreaching.
