Quick Answers

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

Yes. Radeon RX 6600 LE is clearly the better overall GPU here. Radeon RX 6600 LE averages 9.6% more FPS across 49 tracked games in our benchmark data. You are also looking at 13,758 vs 14,018 in G3D Mark. On top of that, Radeon RX 6600 LE is a 2023 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 6600 LE is the more future-proof choice for 2026 and beyond. You are getting a newer 2023 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 6600 LE is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. Radeon RX 6600 LE is about $4,070 cheaper on MSRP at $329 MSRP versus $4,399 MSRP, and you are getting 9.6% more estimated average FPS across 49 tracked games in our benchmark data and a lower G3D Mark (13,758 vs 14,018). It also leads G3D-per-dollar by 1212.3%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

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

Yes. Radeon Pro Vega II Duo 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 $4,399 MSRP, even if Radeon RX 6600 LE is still the cleaner recommendation on overall value today.
