Quick Answers

So, is Radeon RX Vega 9 better than Radeon R9 M375X?

Yes. Radeon RX Vega 9 is clearly the better overall GPU here. Radeon RX Vega 9 averages 84.5% more FPS across 50 tracked games in our benchmark data. You are also looking at 1,661 vs 1,711 in G3D Mark. On top of that, Radeon RX Vega 9 is a 2017 card with FSR upscaling, while Radeon R9 M375X is a 2015 model from an older generation with FSR upscaling. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.

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

Radeon R9 M375X is the more future-proof choice for 2026 and beyond. You are getting more VRAM at 4 GB instead of Unknown. 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 Vega 9 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. Radeon RX Vega 9 is about $151 cheaper on MSRP at $99 MSRP versus $250 MSRP, and you are getting 84.5% more estimated average FPS across 50 tracked games in our benchmark data and a lower G3D Mark (1,661 vs 1,711). It also leads G3D-per-dollar by 145.1%. Radeon R9 M375X is the more forward-looking alternative, so it still has a real case if you care more about future-proofing than about squeezing out the strongest gaming value today.

When does Radeon R9 M375X make more sense than Radeon RX Vega 9?

Yes. Radeon R9 M375X is still an excellent gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It makes more sense if your priority is future-proofing and staying closer to $250 MSRP more than squeezing out the extra headroom of Radeon RX Vega 9. The trade-off is that Radeon RX Vega 9 currently gives you a lower G3D Mark (1,661 vs 1,711) and 84.5% more estimated average FPS across 50 tracked games in our benchmark data. It also leads G3D-per-dollar by 145.1%.
