Quick Answers

So, is Radeon RX 6800 XT better than GeForce GTX 1080 SLI (móvel)?

Yes. Radeon RX 6800 XT is clearly the better overall GPU here. Radeon RX 6800 XT averages 108.9% more FPS across 50 tracked games in our benchmark data. You are also looking at 24,995 vs 26,543 in G3D Mark. On top of that, Radeon RX 6800 XT is a 2020 card with FSR 3 + AFMF, while GeForce GTX 1080 SLI (móvel) is a 2016 model from an older high-end class 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 6800 XT is the more future-proof choice for 2026 and beyond. You are getting a newer 2020 generation instead of 2016, 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 16nm. 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?

Radeon RX 6800 XT is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. Radeon RX 6800 XT is priced in an unclear MSRP range at $649 MSRP versus an unclear MSRP, and you are getting 108.9% more estimated average FPS across 50 tracked games in our benchmark data and a lower G3D Mark (24,995 vs 26,543). 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 1080 SLI (móvel) still worth buying for gaming in 2026?

Yes. GeForce GTX 1080 SLI (móvel) is still a strong modern gaming GPU: it is excellent for 1080p, very strong for 1440p, and still capable at 4K with sensible settings or upscaling. It remains a good buy when you can get it meaningfully cheaper than the alternative around an unclear MSRP, even if Radeon RX 6800 XT is still the cleaner recommendation on overall value today.

Advanced Features (DLSS/FSR)

A critical advantage for the Radeon RX 6800 XT 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 1080 SLI (móvel) lacks specific hardware/driver support for this native frame generation tier.The GeForce GTX 1080 SLI (móvel) gives access to NVIDIA DLSS (Deep Learning Super Sampling), widely regarding as the superior upscaling method for image quality. The Radeon RX 6800 XT relies on FSR (FidelityFX Super Resolution), which is capable but generally slightly noisier than DLSS in motion.
