Quick Answers

So, is Arc B580 better than Radeon Pro V620 MxGPU?

Yes. Arc B580 is clearly the better overall GPU here. Arc B580 averages 27.8% more FPS across 33 tracked games in our benchmark data. You are also looking at 15,977 vs 15,633 in G3D Mark. On top of that, Arc B580 is a 2024 card with no meaningful modern upscaling stack, while Radeon Pro V620 MxGPU is a 2018 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?

Arc B580 is the more future-proof choice for 2026 and beyond. You are getting a newer 2024 generation instead of 2018, the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling, and a 5nm process instead of 14nm. 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?

Arc B580 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. Arc B580 is priced in an unclear MSRP range at $249 MSRP versus an unclear MSRP, and you are getting 27.8% more estimated average FPS across 33 tracked games in our benchmark data and 2.2% higher G3D Mark. It also leads G3D-per-dollar by 100+%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

Is Radeon Pro V620 MxGPU still worth buying for gaming in 2026?

Yes. Radeon Pro V620 MxGPU 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 an unclear MSRP, even if Arc B580 is still the cleaner recommendation on overall value today.
