Slim 3 15.3 with Ryzen 7 8840HS

This 15.3-inch laptop pairs an eight-core Ryzen 7 8840HS processor with 16 GB of DDR5 memory and a 1 TB M.2 drive. Windows 11 Home is pre-installed. The WUXGA IPS panel delivers 1920 x 1200 resolution at 60 Hz. It suits students and professionals who need a portable machine for everyday productivity and light creative work.

Sustained workloads with the integrated Radeon

The 8840HS runs at up to 5.10 GHz turbo frequency with 16 MB L3 cache and a dedicated NPU rated at 16 TOPS for AI tasks. Shared DDR5 memory at 5600 MHz feeds both CPU and graphics cores. In extended sessions the chip maintains clocks without aggressive throttling, so compile times and video exports stay consistent rather than dropping after a short burst.

Thermals, noise and power draw in daily use

A 3-cell battery provides up to 14.80 hours of typical usage. The slim chassis measures 13.5 x 9.4 x 0.70 in and weighs 3.51 lb. Fan noise remains low during office tasks and web browsing, rising only under heavy compute loads. The 300-nit IPS screen with 45% NTSC coverage draws modest power, helping the system stay cool and quiet for most of the working day.
