Radeon Pro V620 MxGPU

2018

Why buy it

✅300% more VRAM for high-resolution textures and newer games (32 GB vs 8 GB).

Trade-offs

❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌Limited future-proofing: older hardware, 32 GB of VRAM, and weaker feature support mean it will age faster in upcoming AAA games.
❌Lower G3D Mark per dollar, at 0 vs 19.8 G3D/$ (Unknown MSRP vs $800 MSRP).
❌200% higher power demand at 300W vs 100W.

Radeon RX 6800S

2022

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 19.8 vs 0 G3D/$ ($800 MSRP vs Unknown MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
✅More future proof: RDNA 2.0 on 7nm with a newer platform for upcoming games.
✅Draws 100W instead of 300W, a 200W reduction.

Trade-offs

❌Less VRAM, with 8 GB vs 32 GB for high-resolution textures and newer games.

Quick Answers

So, is Radeon RX 6800S better than Radeon Pro V620 MxGPU?

Yes. Radeon RX 6800S is clearly the better overall GPU here. You are also looking at 15,841 vs 15,633 in G3D Mark. On top of that, Radeon RX 6800S is a 2022 card with FSR 3 + AFMF, 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?

Radeon RX 6800S is the more future-proof choice for 2026 and beyond. You are getting a newer 2022 generation instead of 2018, better frame-generation support with FSR Frame Generation + AFMF (2023) instead of FSR upscaling, and a 7nm 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?

Radeon RX 6800S can still make sense if you find it at the right price, especially around $800 MSRP. Radeon RX 6800S is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon RX 6800S is priced in an unclear MSRP range at $800 MSRP versus an unclear MSRP, and you are getting 1.3% higher G3D Mark. Moving to $800 MSRP gets you newer hardware, lower power draw (100W vs 300W), and FSR 3 + AFMF.

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

Yes. Radeon Pro V620 MxGPU 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 an unclear MSRP, it remains a very sensible buy. Radeon RX 6800S is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and FSR 3 + AFMF.
