Quick Answers

So, is Radeon RX 6600 XT better than Radeon RX 5700 XT?

Yes. Radeon RX 6600 XT is the better GPU overall here. You are getting 15.9% more average FPS across 50 tracked games in our benchmark data and 1.7% higher PassMark G3D performance. It also comes from 2021 instead of 2019, which helps its case as the more complete modern gaming card.

Which one is more future-proof for 2026 and beyond?

Radeon RX 6600 XT is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2019 and better frame-generation support with FSR Frame Generation + AFMF (2023) instead of FSR Frame Generation (2023). 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 6600 XT is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. Radeon RX 6600 XT is about $70 cheaper on MSRP at $379 MSRP versus $449 MSRP, and you are getting 15.9% more estimated average FPS across 50 tracked games in our benchmark data and 1.7% higher G3D Mark. It also leads G3D-per-dollar by 20.4%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

Is Radeon RX 5700 XT still worth buying for gaming in 2026?

Yes. Radeon RX 5700 XT 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 $449 MSRP, even if Radeon RX 6600 XT is still the cleaner recommendation on overall value today.
