GeForce RTX 3080 Laptop GPU

2021

Why buy it

✅43.0% more average FPS across 45 tracked games in our benchmark data.
✅Access to DLSS 2 Super Resolution (2020).
✅More future proof: Ampere (2020−2025) on 8nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with 8 GB vs 32 GB for high-resolution textures and newer games.
❌16.7% higher power demand at 350W vs 300W.

Radeon Pro V620 MxGPU

2018

Why buy it

✅300% more VRAM for high-resolution textures and newer games (32 GB vs 8 GB).
✅Draws 300W instead of 350W, a 50W reduction.

Trade-offs

❌Lower average FPS than GeForce RTX 3080 Laptop GPU across 45 tracked games in our benchmark data.
❌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.

Quick Answers

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

Yes. GeForce RTX 3080 Laptop GPU is clearly the better overall GPU here. GeForce RTX 3080 Laptop GPU averages 43.0% more FPS across 45 tracked games in our benchmark data. You are also looking at 16,233 vs 15,633 in G3D Mark. On top of that, GeForce RTX 3080 Laptop GPU 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 Laptop GPU 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 Laptop GPU is priced in an unclear MSRP range at an unclear MSRP versus an unclear MSRP, and you are getting 43.0% more estimated average FPS across 45 tracked games in our benchmark data and 3.8% higher G3D Mark. G3D-per-dollar is basically tied between them. If you are comfortable paying the premium for the stronger gaming result, GeForce RTX 3080 Laptop GPU is the one to buy. If staying closer to budget matters more, Radeon Pro V620 MxGPU still makes more sense on price alone, but the performance trade-off is much harder to justify by current standards.

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

Yes. Radeon Pro V620 MxGPU is still a strong gaming GPU in 2026: it is very strong for 1080p, good for 1440p, and more limited at 4K. This mostly comes down to price. If you want to stay closer to an unclear MSRP, it remains a strong choice; if you are comfortable paying more, GeForce RTX 3080 Laptop GPU earns that extra money with a clearly stronger gaming result and a more complete overall package.
