[Comparison] AMD Ryzen 3 5300U vs AMD Ryzen 3 4300U – The Ryzen 3 4300U really gave it all but it wasn’t enough

With the “new” Ryzen 5000 U-series hitting the shelves, inside many laptops, we had to see what the fuss about rebranded older chips was about. While we are against rebranding old stuff and selling it as new, we understand AMD’s perspective: they have them in stock, so why not use them.

Also with the chip shortage that is happening right now, people will eat these processors, as they are still capable performers, despite being more than a year old at this point. Today we have the Ryzen 3 5300U, which will go against the Ryzen 3 4300U, to see how great is this “new” Ryzen processor.

CPU benchmarks

In the 3D Rendering benchmark with Cinebench 20, the Ryzen 3 5300U managed to surpass its sibling, scoring 26% higher. In the second test, with Adobe Photoshop, the scores were much more competitive, with the Ryzen 3 4300U actually winning out, despite being the underdog, finishing 0.37 seconds faster.

Results are from the Cinebench R23 CPU test (the higher the score, the better)

Results are from our Photoshop benchmark test (the lower the score, the better)

GPU benchmarks

Moving over to the GPU benchmarks, the RX Vega 6 inside the Ryzen 3 5300U dominated in all three benchmarks, performing 17%, 13%, and 18% better in 3DMark Fire Strike, Unigine Heaven 4.0, and Unigine Superposition, respectively. The iGPU also performed better in our gaming tests, as it had higher fps in both CS:GO and DOTA 2, regardless of the settings presets.

Results are from the 3DMark: Time Spy (Graphics) benchmark (higher the score, the better)

To conclude, both CPUs performed admirably, but we have to give the victory to the Ryzen 3 5300U. It was the overall better chip, albeit it lost the Photoshop battle. Still, the Ryzen 3 4300U showed up and was here to fight. It is also the more affordable processor, as laptops with it start at around 400$. Both of these processors can be great for a school laptop, and can even handle some light to medium workloads.
