AMD Ryzen 3 5300U vs AMD Ryzen 3 5400U: Comparison
Ryzen 3 5300U vs Ryzen 3 5400U: the l3 cache difference
The gap that matters here is l3 cache: Ryzen 3 5300U 4 MB against Ryzen 3 5400U 8 MB, which puts Ryzen 3 5400U 50% ahead. There is a split on p-core boost clock as well, 3.8 GHz on the Ryzen 3 5300U versus 4.0 GHz on the Ryzen 3 5400U. Product line is not the same on both, Ryzen 3 on the Ryzen 3 5300U versus Ryzen on the Ryzen 3 5400U. They differ on form factor too, Laptop on the Ryzen 3 5300U versus Laptops, Desktops on the Ryzen 3 5400U. Igpu is not the same on both, AMD Radeon RX Vega 6 on the Ryzen 3 5300U versus AMD Radeon Graphics on the Ryzen 3 5400U. They differ on memory type too, DDR4-3200, LPDDR4-4266 on the Ryzen 3 5300U versus DDR4, LPDDR4 on the Ryzen 3 5400U.
Who each one is for
Take the Ryzen 3 5300U for budget thin-and-light laptops wanting genuine hyperthreaded multi-tasking capability at the entry tier. Avoid it for buyers wanting true Zen 3 architecture, this chip uses the Zen 2-based Lucienne design despite the Ryzen 5000 badge. Buy the Ryzen 3 5400U for mainstream desktop builds and everyday productivity, though it is not built for extreme overclocking (unless K/X-series) and workstation-class multi-threaded workloads.
Where the two are identical
Where they agree, they agree completely, total cores, performance cores, efficiency cores, total threads and p-core base clock included, so the decision does not turn on any of those. They match on 8 further specifications as well.
Frequently asked questions
Is the TDP the same on the Ryzen 3 5300U and Ryzen 3 5400U?
It is. Both are listed at 15 W, so it is not a reason to pick one over the other.
