Quick Answers

So, is GeForce RTX 3070 better than RadeonT 660M?

Yes. GeForce RTX 3070 is clearly the better overall GPU here. You are also looking at 22,172 vs 2,221 in G3D Mark. On top of that, GeForce RTX 3070 is a 2020 card with DLSS Super Resolution, while RadeonT 660M is a 2023 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?

GeForce RTX 3070 is the more future-proof choice for 2026 and beyond. You are getting 898.3% more raw performance headroom, more VRAM at 8 GB instead of 2 GB, and the stronger feature stack with DLSS Super Resolution instead of FSR upscaling. That leaves it with more room for heavier textures, tougher ray tracing loads, and higher-end 1440p or 4K gaming over the next few years.

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

GeForce RTX 3070 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. GeForce RTX 3070 is priced in an unclear MSRP range at $499 MSRP versus an unclear MSRP, and you are getting 898.3% higher G3D Mark. It also leads G3D-per-dollar by 100+%. RadeonT 660M is the newer 2023 card, so it still has a real case if you care more about newer architecture and lower power draw (40W vs 220W) than about squeezing out the strongest gaming value today.

When does RadeonT 660M make more sense than GeForce RTX 3070?

Yes. RadeonT 660M 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 (40W vs 220W), and staying closer to an unclear MSRP more than squeezing out the extra headroom of GeForce RTX 3070. The trade-off is that GeForce RTX 3070 currently gives you 898.3% higher G3D Mark. It also leads G3D-per-dollar by 100+%.
