Quick Answers

So, is GeForce RTX 4070 better than Radeon Pro V620 MxGPU?

Yes. GeForce RTX 4070 is clearly the better overall GPU here. You are also looking at 26,919 vs 15,633 in G3D Mark. On top of that, GeForce RTX 4070 is a 2023 card with DLSS 3.5 + Frame Generation, 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 4070 is the more future-proof choice for 2026 and beyond. You are getting a newer 2023 generation instead of 2018, 72.2% more raw performance headroom, better frame-generation support with DLSS 3.5 + Frame Generation (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?

GeForce RTX 4070 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. GeForce RTX 4070 is priced in an unclear MSRP range at $599 MSRP versus an unclear MSRP, and you are getting 72.2% 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 4070 is still the cleaner recommendation on overall value today.

Advanced Features (DLSS/FSR)

A critical advantage for the GeForce RTX 4070 is support for DLSS 3.5 + Frame Generation. This allows it to generate entire frames using AI/Algorithms, essentially doubling the frame rate in CPU-bound scenarios or heavy ray-tracing titles. The Radeon Pro V620 MxGPU lacks specific hardware/driver support for this native frame generation tier.The GeForce RTX 4070 gives access to NVIDIA DLSS (Deep Learning Super Sampling), widely regarding as the superior upscaling method for image quality. The Radeon Pro V620 MxGPU relies on FSR (FidelityFX Super Resolution), which is capable but generally slightly noisier than DLSS in motion.
