Lenovo LOQ 15IRH8 15.6" Intel Core i5-12450H 2.4GHz / Nvidia GeForce RTX 4050 Laptop / 16GB RAM / 512GB SSD

Manufacturer: Lenovo

The Lenovo LOQ 15IRH8 is a 15.6″ gaming laptop built around an Intel Core i5-12450H processor and an Nvidia GeForce RTX 4050 graphics card. Weighing 2,400 g and measuring 22 mm thick, it occupies a relatively compact footprint for its class. The machine ships with 16GB of DDR5 RAM and a 512GB NVMe SSD, and supports up to 32GB across its two memory slots. A backlit keyboard and stereo speakers round out the day-to-day usability features.

The IPS display runs at 1920 x 1080 px across a 15.6″ panel, delivering a pixel density of 141 ppi, a typical brightness of 350 nits, and a 144Hz refresh rate with an anti-reflection coating. On the graphics side, the RTX 4050 is based on the Ada Lovelace architecture, carries 6GB of GDDR6 VRAM on a 96-bit bus, and posts a floating-point performance figure of 12.13 TFLOPS with support for ray tracing and DLSS. Connectivity includes one USB 3.2 Gen 2 Type-C port, two USB 3.2 Gen 2 Type-A ports, one USB 3.2 Gen 1 Type-A port, HDMI 2.1, Wi-Fi 6, Bluetooth 5.2, and a single RJ45 Ethernet jack. The 60 Wh battery supports sleep-and-charge, and the unit carries a two-year warranty.

Pros
  • The 144Hz IPS display with anti-reflection coating and 350 nits brightness provides smooth visuals in varied lighting conditions
  • Support for ray tracing and DLSS expands graphical rendering options for compatible games and applications
  • The NVMe SSD on a PCIe 4.0 interface enables fast storage read and write operations
  • Wi-Fi 6 support alongside Bluetooth 5.2 offers modern wireless connectivity
  • The two-memory-slot configuration supports upgrades up to 32GB, giving room to expand beyond the stock 16GB
  • Sleep-and-charge USB ports allow connected devices to be powered even when the laptop is off or in sleep mode
Cons
  • The 96-bit memory bus width on the GPU is narrower than what higher-tier discrete graphics typically use, limiting memory throughput headroom
  • No Thunderbolt 3 or 4 ports and no USB 4 support restricts high-bandwidth peripheral and external display options
  • The 60 Wh battery is modest for a gaming laptop with a 115W TDP processor, which can draw heavily on battery reserves
  • There is no fingerprint scanner or 3D facial recognition, leaving the system without biometric login options
  • No external memory card slot limits quick file transfers from cameras or other card-based devices
Who is this for?

This laptop is a solid fit for users who want a capable machine for casual to mid-range gaming, thanks to its RTX 4050 with ray tracing and DLSS support, 144Hz IPS display, and 12.13 TFLOPS of floating-point performance. Students or professionals who also handle everyday productivity and multimedia tasks will appreciate the 16GB of DDR5 RAM, 512GB NVMe SSD, and a bright anti-reflection display suited for extended screen time. Its Wi-Fi 6 support, multiple USB ports, and HDMI 2.1 output also make it practical for users who regularly connect to external displays or peripherals in a desk or campus environment.

Who is this NOT for?

Users who need a machine for demanding AAA gaming at high graphical settings may find the RTX 4050's 6GB GDDR6 VRAM on a 96-bit bus limiting, particularly in scenarios involving high-resolution textures or future titles with heavier VRAM requirements. The 60 Wh battery paired with a 115W TDP processor makes this a poor choice for anyone needing extended unplugged usage, as heavy workloads will drain the battery quickly. Similarly, creative professionals requiring Thunderbolt connectivity, high-speed external storage, or precise biometric security will find the absence of Thunderbolt ports, no fingerprint scanner, and no facial recognition a notable gap for their workflows.
