Quick Answers

So, is GeForce RTX 4070 better than RadeonT 660M?

Yes. GeForce RTX 4070 is clearly the better overall GPU here. GeForce RTX 4070 averages 644.4% more FPS across 49 tracked games in our benchmark data. You are also looking at 26,919 vs 2,221 in G3D Mark. On top of that, GeForce RTX 4070 is a 2023 card with DLSS 3.5 + Frame Generation, 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 4070 is the more future-proof choice for 2026 and beyond. You are getting 1112.0% more raw performance headroom, more VRAM at 12 GB instead of 2 GB, better frame-generation support with DLSS 3.5 + Frame Generation (2023) instead of FSR upscaling, and a 5nm process instead of 6nm. 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 644.4% more estimated average FPS across 49 tracked games in our benchmark data and 1112.0% 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 RadeonT 660M still worth buying for gaming in 2026?

Yes. RadeonT 660M 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.

Advanced Features (DLSS/FSR)

A critical advantage for the GeForce RTX 4070 is support for DLSS 3.5 + Frame Generation. This allows it to generate entire frames using AI/Algorithms, essentially doubling the frame rate in CPU-bound scenarios or heavy ray-tracing titles. The RadeonT 660M lacks specific hardware/driver support for this native frame generation tier.The GeForce RTX 4070 gives access to NVIDIA DLSS (Deep Learning Super Sampling), widely regarding as the superior upscaling method for image quality. The RadeonT 660M relies on FSR (FidelityFX Super Resolution), which is capable but generally slightly noisier than DLSS in motion.
