Radeon 880M

2024

Why buy it

✅Draws 15W instead of 53W, a 38W reduction.
✅More future proof: RDNA 3.5 (2024−2025) on 4nm with a newer platform for upcoming games.

Trade-offs

❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌Lower G3D Mark per dollar, at 0 vs 48.6 G3D/$ (Unknown MSRP vs $159 MSRP).

Radeon RX 6400

2022

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 48.6 vs 0 G3D/$ ($159 MSRP vs Unknown MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).

Trade-offs

❌253.3% higher power demand at 53W vs 15W.

Quick Answers

So, is Radeon 880M better than Radeon RX 6400?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 7,729 vs 7,728 in G3D Mark. The bigger reason to prefer Radeon 880M is the overall package: you are getting a newer generation, FSR upscaling, plus much lower power draw (15W vs 53W).

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

Radeon 880M is the more future-proof choice for 2026 and beyond. You are getting a newer 2024 generation instead of 2022, better upscaling support with FSR Upscaling / FSR 4 (2025) instead of FSR 3 (2023), and a 4nm process instead of 6nm. That broader feature stack should age better as more games lean on modern upscaling and frame-generation support.

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

Radeon RX 6400 can still make sense if you find it at the right price, especially around $159 MSRP. Radeon 880M is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon 880M is priced in an unclear MSRP range at an unclear MSRP versus $159 MSRP, and you are getting 0.0% higher G3D Mark. Moving to an unclear MSRP gets you newer hardware, lower power draw (15W vs 53W), and FSR upscaling.

Is Radeon RX 6400 still worth buying for gaming in 2026?

Yes. Radeon RX 6400 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 $159 MSRP, it remains a very sensible buy. Radeon 880M is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and FSR upscaling.
