Quick Answers

So, is Radeon Pro Vega 64X better than Radeon RX 6600S?

Yes. Radeon Pro Vega 64X is clearly the better overall GPU here. Radeon Pro Vega 64X averages 3.2% more FPS across 50 tracked games in our benchmark data. You are also looking at 13,369 vs 13,016 in G3D Mark. On top of that, Radeon Pro Vega 64X is a 2019 card with FSR upscaling, 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?

Radeon RX 6600S is the more future-proof choice for 2026 and beyond. You are getting a newer 2022 generation instead of 2019, more VRAM at 4 GB instead of Unknown, better frame-generation support with FSR Frame Generation + AFMF (2023) instead of FSR upscaling, and a 7nm process instead of 14nm. 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 Pro Vega 64X is the smarter buy by a wide margin. Radeon Pro Vega 64X is about 450.0% more expensive on MSRP at $2,200 MSRP versus $400 MSRP, and you are getting 3.2% more estimated average FPS across 50 tracked games in our benchmark data and 2.7% higher G3D Mark. Radeon RX 6600S really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does Radeon RX 6600S make more sense than Radeon Pro Vega 64X?

Yes. Radeon RX 6600S is still an excellent gaming GPU in 2026: it is very strong for 1080p, good for 1440p, and more limited at 4K. It makes more sense if your priority is newer architecture, lower power draw (80W vs 250W), future-proofing, and staying closer to $400 MSRP more than squeezing out the extra headroom of Radeon Pro Vega 64X. The trade-off is that Radeon Pro Vega 64X currently gives you 2.7% higher G3D Mark and 3.2% more estimated average FPS across 50 tracked games in our benchmark data. Radeon RX 6600S still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
