Quick Answers

So, is GeForce RTX 4070 better than GeForce GTX 1660 Ti (Mobile)?

Yes. GeForce RTX 4070 is clearly the better overall GPU here. GeForce RTX 4070 averages 117.0% more FPS across 44 tracked games in our benchmark data. You are also looking at 26,919 vs 10,119 in G3D Mark. On top of that, GeForce RTX 4070 is a 2023 card with DLSS 3.5 + Frame Generation, while GeForce GTX 1660 Ti (Mobile) 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?

GeForce RTX 4070 is the more future-proof choice for 2026 and beyond. You are getting a newer 2023 generation instead of 2020, 166.0% more raw performance headroom, more VRAM at 12 GB instead of 6 GB, and better upscaling support with DLSS 3.5 Super Resolution (2023) instead of no meaningful modern upscaling stack and better frame-generation support with DLSS 3.5 + Frame Generation (2023) instead of no meaningful modern upscaling stack. 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 4070 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. GeForce RTX 4070 is priced in an unclear MSRP range at $599 MSRP versus an unclear MSRP, and you are getting 117.0% more estimated average FPS across 44 tracked games in our benchmark data and 166.0% higher G3D Mark. It also leads G3D-per-dollar by 100+%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

Is GeForce GTX 1660 Ti (Mobile) still worth buying for gaming in 2026?

Yes. GeForce GTX 1660 Ti (Mobile) is still a strong modern gaming GPU: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It remains a good buy when you can get it meaningfully cheaper than the alternative around an unclear MSRP, even if GeForce RTX 4070 is still the cleaner recommendation on overall value today.
