Quick Answers

So, is GeForce GTX 1660 Ti (móvel) better than Radeon 8040S?

Yes. GeForce GTX 1660 Ti (móvel) is clearly the better overall GPU here. GeForce GTX 1660 Ti (móvel) averages 74.6% more FPS across 49 tracked games in our benchmark data. You are also looking at 10,128 vs 9,756 in G3D Mark. On top of that, GeForce GTX 1660 Ti (móvel) is a 2019 card with no meaningful modern upscaling stack, while Radeon 8040S is a 2025 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 8040S is the more future-proof choice for 2026 and beyond. You are getting a newer 2025 generation instead of 2019, 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 GTX 1660 Ti (móvel) is priced in an unclear MSRP range at an unclear MSRP versus $400 MSRP, and you are getting 74.6% more estimated average FPS across 49 tracked games in our benchmark data and 3.8% higher G3D Mark. Radeon 8040S still holds the G3D-per-dollar lead, so the performance win comes with a real value premium. If you are comfortable paying the premium for the stronger gaming result, GeForce GTX 1660 Ti (móvel) is the one to buy. If staying closer to budget matters more, Radeon 8040S still makes more sense on price alone, but the performance trade-off is much harder to justify by current standards.

When does Radeon 8040S make more sense than GeForce GTX 1660 Ti (móvel)?

Yes. Radeon 8040S 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 newer architecture, lower power draw (55W vs 80W), future-proofing, and staying closer to $400 MSRP more than squeezing out the extra headroom of GeForce GTX 1660 Ti (móvel). The trade-off is that GeForce GTX 1660 Ti (móvel) currently gives you 3.8% higher G3D Mark and 74.6% more estimated average FPS across 49 tracked games in our benchmark data. Radeon 8040S still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
