Quick Answers

So, is Radeon RX 6600S better than GeForce GTX 1660 SUPER?

Yes. Radeon RX 6600S is clearly the better overall GPU here. GeForce GTX 1660 SUPER averages 7.0% more FPS across 43 tracked games in our benchmark data. You are also looking at 13,016 vs 12,692 in G3D Mark. On top of that, Radeon RX 6600S is a 2022 card with FSR 3 + AFMF, while GeForce GTX 1660 SUPER is a 2019 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 RX 6600S is the more future-proof choice for 2026 and beyond. You are getting a newer 2022 generation instead of 2019, better upscaling support with FSR 3 (2023) instead of no meaningful modern upscaling stack and better frame-generation support with FSR Frame Generation + AFMF (2023) instead of no meaningful modern upscaling stack, and a 7nm 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 SUPER can still make sense if you find it at the right price, especially around $229 MSRP. Radeon RX 6600S is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon RX 6600S is about 74.7% more expensive on MSRP at $400 MSRP versus $229 MSRP, and you are getting lower estimated average FPS across 43 tracked games in our benchmark data and 2.6% higher G3D Mark. Moving to $400 MSRP gets you newer hardware, lower power draw (80W vs 125W), and FSR 3 + AFMF.

Is GeForce GTX 1660 SUPER still worth buying for gaming in 2026?

Yes. GeForce GTX 1660 SUPER is still a strong gaming card in 2026: it is very strong for 1080p, good for 1440p, and more limited at 4K. Price is really the swing factor here. If you find it at or below $229 MSRP, it remains a very sensible buy. Radeon RX 6600S is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and FSR 3 + AFMF.

Advanced Features (DLSS/FSR)

A critical advantage for the Radeon RX 6600S is support for FSR Frame Generation + AFMF. 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 GeForce GTX 1660 SUPER lacks specific hardware/driver support for this native frame generation tier.The GeForce GTX 1660 SUPER gives access to NVIDIA DLSS (Deep Learning Super Sampling), widely regarding as the superior upscaling method for image quality. The Radeon RX 6600S relies on FSR (FidelityFX Super Resolution), which is capable but generally slightly noisier than DLSS in motion.
