GeForce RTX 3080 Mobile

2021

Why buy it

✅Access to DLSS 2 Super Resolution (2020).
✅More future proof: Ampere on 8nm with a newer platform for upcoming games.
✅Draws 115W instead of 300W, a 185W reduction.

Trade-offs

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

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 DLSS support; it relies on FSR Upscaling / FSR 4 (2025) instead.
❌Limited future-proofing: older hardware, 32 GB of VRAM, and weaker feature support mean it will age faster in upcoming AAA games.
❌160.9% higher power demand at 300W vs 115W.

Quick Answers

So, is GeForce RTX 3080 Mobile better than Radeon Pro V620 MxGPU?

Yes. GeForce RTX 3080 Mobile is clearly the better overall GPU here. You are also looking at 16,214 vs 15,633 in G3D Mark. On top of that, GeForce RTX 3080 Mobile is a 2021 card with DLSS Super Resolution, 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?

GeForce RTX 3080 Mobile is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2018, the stronger feature stack with DLSS Super Resolution instead of FSR upscaling, and a 8nm 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?

GeForce RTX 3080 Mobile can still make sense if you find it at the right price, especially around Unknown MSRP. GeForce RTX 3080 Mobile is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. GeForce RTX 3080 Mobile is priced in an unclear MSRP range at an unclear MSRP versus an unclear MSRP, and you are getting 3.7% higher G3D Mark. Moving to an unclear MSRP gets you newer hardware, lower power draw (115W vs 300W), and DLSS Super Resolution.

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. GeForce RTX 3080 Mobile is still the safer recommendation for most fresh builds because it offers a cleaner overall package with newer hardware and DLSS Super Resolution.
