Verdict

The AMD Ryzen 3 5400U is an entry-level mobile processor based on the Zen 3 'Cezanne' architecture, featuring 4 cores and 8 threads with a base clock of 2.6 GHz and a boost frequency up to 4.0 GHz. Built on a 7 nm process, it includes 8 MB of L3 cache, an integrated Radeon RX Vega 6 GPU clocked at 1600 MHz, and a configurable TDP ranging from 10W to 25W. Its main pros include excellent energy efficiency for thin laptops, significant IPC improvements over previous Zen 2 generations, and solid performance for everyday multitasking and light office work. However, its cons include limited capability for heavy AAA gaming or professional video editing, and it lacks support for newer standards like PCIe 4.0 or DDR5 RAM.
