Lenovo Flex 5 81X20005 laptop Ryzen 5 4500U 16GB 2TB SSD 14.0" touchscreen

Flex 5 2-in-1 design

The Lenovo Flex 5 81X20005 is a 14.0 inch convertible laptop with a 360 degree hinge that switches between laptop and tablet modes. It runs Windows 10 Pro on an AMD Ryzen 5 4500U processor with 16GB DDR4 memory and a 2TB SSD. The integrated AMD Radeon Graphics handle everyday visual tasks. A fingerprint reader and backlit keyboard are included.

Sustained workload behaviour

The 4th Gen Ryzen 5 4500U operates at a 2.30GHz base clock across six cores for steady multi-threaded throughput. Integrated Radeon graphics share system memory during extended creative or productivity sessions. The 2TB solid state drive maintains consistent read and write speeds without thermal throttling typical of mechanical drives. DDR4 memory bandwidth supports prolonged multitasking without paging delays.

Thermals noise and power

The ultra-thin chassis uses passive and active cooling to manage heat from the processor and integrated graphics under normal loads. Fan noise remains low during typical office work and media playback. Power draw stays within the limits of the supplied adapter for efficient operation. The 14.0 inch IPS touchscreen display draws modest power at 1920 x 1080 resolution.
