Quick Answers

So, is GeForce RTX 4070 better than Radeon RX 6600S?

Yes. GeForce RTX 4070 is clearly the better overall GPU here. You are also looking at 26,919 vs 13,016 in G3D Mark. On top of that, GeForce RTX 4070 is a 2023 card with DLSS 3.5 + Frame Generation, while Radeon RX 6600S is a 2022 model from an older generation with FSR 3 + AFMF. 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 2022, 106.8% more raw performance headroom, more VRAM at 12 GB instead of 4 GB, and the stronger feature stack with DLSS 3.5 + Frame Generation instead of FSR 3 + AFMF. 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 about 49.8% more expensive on MSRP at $599 MSRP versus $400 MSRP, and you are getting 106.8% higher G3D Mark. It also leads G3D-per-dollar by 38.1%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

Is Radeon RX 6600S still worth buying for gaming in 2026?

Yes. Radeon RX 6600S is still a strong modern gaming GPU: it is very strong for 1080p, good for 1440p, and more limited at 4K. It remains a good buy when you can get it meaningfully cheaper than the alternative around $400 MSRP, even if GeForce RTX 4070 is still the cleaner recommendation on overall value today.

Advanced Features (DLSS/FSR)

Both GPUs support Frame Generation technologies, but they achieve it differently. The GeForce RTX 4070 uses DLSS 3.5 + Frame Generation, while the Radeon RX 6600S relies on FSR Frame Generation + AFMF. Both can significantly boost FPS in supported titles, but they are not on the same feature stack.The GeForce RTX 4070 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.
