Quick Answers

So, is Radeon RX 6400 better than Radeon RX 5300?

Yes, but this is not really about a huge raw performance gap. Radeon RX 5300 averages 3.0% more FPS across 50 tracked games in our benchmark data. The broader synthetic picture is also very close at 7,606 vs 7,728 in G3D Mark. The bigger reason to prefer Radeon RX 6400 is the overall package: you are getting a newer generation, FSR 3 + AFMF, plus much lower power draw (53W vs 100W).

Which one is more future-proof for 2026 and beyond?

Radeon RX 6400 is the more future-proof choice for 2026 and beyond. You are getting a newer 2022 generation instead of 2020, more VRAM at 4 GB instead of 3 GB, better frame-generation support with FSR Frame Generation + AFMF (2023) instead of FSR Frame Generation (2023), and a 6nm process instead of 7nm. That extra memory headroom makes it the safer pick for newer games, heavier textures, and higher settings over time.

Which one is the smarter buy today, not just the cheaper card?

Radeon RX 5300 can still make sense if you find it at the right price, especially around $129 MSRP. Radeon RX 6400 is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon RX 6400 is about 23.3% more expensive on MSRP at $159 MSRP versus $129 MSRP, and you are getting lower estimated average FPS across 50 tracked games in our benchmark data and 1.6% higher G3D Mark. Moving to $159 MSRP gets you newer hardware, lower power draw (53W vs 100W), and FSR 3 + AFMF.

Is Radeon RX 5300 still worth buying for gaming in 2026?

Yes. Radeon RX 5300 is still a strong gaming card in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. Price is really the swing factor here. If you find it at or below $129 MSRP, it remains a very sensible buy. Radeon RX 6400 is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and FSR 3 + AFMF.
