Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, raw graphics performance, VRAM, feature set, power efficiency, pricing context, and long-term value so you can see which GPU actually makes more sense.

Radeon Pro V620 MxGPU

2018

Why buy it

✅166.7% more VRAM for high-resolution textures and newer games (32 GB vs 12 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.
❌66.7% higher power demand at 300W vs 180W.

Radeon RX 7800M

2024

Why buy it

✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
✅More future proof: RDNA 3.0 on 5nm with a newer platform for upcoming games.
✅Draws 180W instead of 300W, a 120W reduction.

Trade-offs

❌Less VRAM, with 12 GB vs 32 GB for high-resolution textures and newer games.

Quick Answers

So, is Radeon RX 7800M better than Radeon Pro V620 MxGPU?

Yes. Radeon RX 7800M is clearly the better overall GPU here. You are also looking at 15,984 vs 15,633 in G3D Mark. On top of that, Radeon RX 7800M is a 2024 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 7800M is the more future-proof choice for 2026 and beyond. You are getting a newer 2024 generation instead of 2018, better frame-generation support with FSR Frame Generation + AFMF (2023) 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?

Radeon RX 7800M can still make sense if you find it at the right price, especially around Unknown MSRP. Radeon RX 7800M is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon RX 7800M is priced in an unclear MSRP range at an unclear MSRP versus an unclear MSRP, and you are getting 2.2% higher G3D Mark. Moving to an unclear MSRP gets you newer hardware, lower power draw (180W 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 7800M is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and FSR 3 + AFMF.
