AMD Ryzen 3 5300U Review

Announced January 2021, the AMD Ryzen 3 5300U is a 4-core, 8-thread processor marketed under the Ryzen 5000 series but built on the Zen 2-based Lucienne architecture, running a 2.6 GHz base clock that boosts to 3.8 GHz within a 15 Watt TDP.

With SMT enabled for a full 8 threads on 4 cores, this chip gave AMD's entry-tier Ryzen 3 lineup a genuine multi-threaded boost over the previous generation's non-SMT 4300U.

AMD Radeon RX Vega 6

A 6-compute-unit Vega iGPU, a solid mid-tier integrated graphics configuration for light gaming and everyday use.

How Is the Ryzen 3 5300U in Terms of Performance

The 4-core, 8-thread layout with SMT enabled gives this chip genuine multi-threaded headroom over the non-SMT Ryzen 3 4300U it replaced, delivering solid everyday productivity capability at the entry tier of AMD's 2021 mobile lineup.

Benchmarks

Cinebench R23 (via R20 reference) multi-core scores of 2,055 comfortably lead the non-SMT Ryzen 3 4300U's 1,506 score, directly reflecting the added SMT threads. Geekbench 5 multi-core scores of 4,149 confirm genuinely improved multi-threaded capability for an entry-tier chip.
