Quick Answers

So, is Radeon RX 6600M better than Radeon Pro Vega II Duo?

Yes. Radeon RX 6600M is clearly the better overall GPU here. Radeon RX 6600M averages 9.9% more FPS across 50 tracked games in our benchmark data. You are also looking at 13,922 vs 14,018 in G3D Mark. On top of that, Radeon RX 6600M is a 2021 card with FSR 3 + AFMF, while Radeon Pro Vega II Duo is a 2019 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?

Radeon RX 6600M is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2019, more VRAM at 8 GB instead of Unknown, and better frame-generation support with FSR Frame Generation + AFMF (2023) instead of FSR upscaling. That extra memory headroom makes it the safer pick for newer games, heavier textures, and higher settings over time.

Which one is the smarter buy today, not just the cheaper card?

Radeon RX 6600M is the smarter buy by a wide margin. Radeon RX 6600M is priced in an unclear MSRP range at an unclear MSRP versus $4,399 MSRP, and you are getting 9.9% more estimated average FPS across 50 tracked games in our benchmark data and a lower G3D Mark (13,922 vs 14,018). Radeon Pro Vega II Duo really only makes sense now as a very cheap stopgap or a used-market placeholder.

Is Radeon Pro Vega II Duo still worth buying for gaming in 2026?

No, not for a fresh gaming build. Radeon Pro Vega II Duo is 2019 hardware with Unknown of VRAM, 14,018 in G3D Mark, and FSR upscaling. That is simply too far behind to be an easy modern recommendation.
