Trade-offs

❌Less VRAM, with Unknown vs 4 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌Very weak future-proofing: 2017-era hardware with Unknown of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌
49.8% HIGHER MSRP
$599 MSRPvs$400 MSRP
❌Lower G3D Mark per dollar, at 21.5 vs 32.5 G3D/$ ($599 MSRP vs $400 MSRP).

Radeon RX 6600S

2022

Why buy it

✅Costs $199 less on MSRP ($400 MSRP vs $599 MSRP).
✅Delivers 51.2% more G3D Mark for each dollar spent, at 32.5 vs 21.5 G3D/$ ($400 MSRP vs $599 MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
✅100+% more VRAM for high-resolution textures and newer games (4 GB vs Unknown).
✅More future proof: RDNA 2.0 (2020−2025) on 7nm with a newer platform for upcoming games.

Quick Answers

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

Yes. Radeon RX 6600S is clearly the better overall GPU here. You are also looking at 13,016 vs 12,891 in G3D Mark. On top of that, Radeon RX 6600S is a 2022 card with FSR 3 + AFMF, while Radeon Pro Vega 64 is a 2017 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 6600S is the more future-proof choice for 2026 and beyond. You are getting a newer 2022 generation instead of 2017, 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 RX 6600S can still make sense if you find it at the right price, especially around $400 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 $199 cheaper on MSRP at $400 MSRP versus $599 MSRP, and you are getting 1.0% higher G3D Mark. Moving to $400 MSRP gets you newer hardware, lower power draw (80W vs 250W), and FSR 3 + AFMF.

Is Radeon Pro Vega 64 still worth buying for gaming in 2026?

Yes. Radeon Pro Vega 64 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 $599 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.
