GeForce RTX 3070

2020

Why buy it

✅+41.8% higher PassMark G3D performance.
✅Delivers 100+% more G3D Mark for each dollar spent, at 44.4 vs 0 G3D/$ ($499 MSRP vs Unknown MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅More future proof: Ampere (2020−2025) on 8nm with a newer platform for upcoming games.
✅Draws 220W instead of 300W, a 80W 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

❌Lower PassMark G3D performance (15,633 vs 22,172).
❌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.
❌Lower G3D Mark per dollar, at 0 vs 44.4 G3D/$ (Unknown MSRP vs $499 MSRP).
❌36.4% higher power demand at 300W vs 220W.

Quick Answers

So, is GeForce RTX 3070 better than Radeon Pro V620 MxGPU?

Yes. GeForce RTX 3070 is clearly the better overall GPU here. You are also looking at 22,172 vs 15,633 in G3D Mark. On top of that, GeForce RTX 3070 is a 2020 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 3070 is the more future-proof choice for 2026 and beyond. You are getting a newer 2020 generation instead of 2018, 41.8% more raw performance headroom, 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 3070 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. GeForce RTX 3070 is priced in an unclear MSRP range at $499 MSRP versus an unclear MSRP, and you are getting 41.8% 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 GeForce RTX 3070 is still the cleaner recommendation on overall value today.
