Quick Answers

So, is Radeon 840M better than GeForce MX450?

Yes. Radeon 840M is clearly the better overall GPU here. You are also looking at 3,803 vs 3,720 in G3D Mark. On top of that, Radeon 840M is a 2024 card with FSR upscaling, while GeForce MX450 is a 2020 model from an older generation with no meaningful modern upscaling stack. 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 840M is the more future-proof choice for 2026 and beyond. You are getting a newer 2024 generation instead of 2020, better upscaling support with FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, and a 4nm process instead of 12nm. 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?

GeForce MX450 can still make sense if you find it at the right price, especially around $250 MSRP. Radeon 840M is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon 840M is priced in an unclear MSRP range at an unclear MSRP versus $250 MSRP, and you are getting 2.2% higher G3D Mark. Moving to an unclear MSRP gets you newer hardware, and FSR upscaling.

Is GeForce MX450 still worth buying for gaming in 2026?

Yes. GeForce MX450 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 $250 MSRP, it remains a very sensible buy. Radeon 840M is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and FSR upscaling.
