Quick Answers

So, is GeForce RTX 3070 better than Iris Plus Graphics 645?

Yes. GeForce RTX 3070 is clearly the better overall GPU here. You are also looking at 22,172 vs 1,450 in G3D Mark. On top of that, GeForce RTX 3070 is a 2020 card with DLSS Super Resolution, while Iris Plus Graphics 645 is a 2019 model from an older generation with no meaningful modern upscaling stack. 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 2019, 1429.1% more raw performance headroom, more VRAM at 8 GB instead of Unknown, and better upscaling support with DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack. That leaves it with more room for heavier textures, tougher ray tracing loads, and higher-end 1440p or 4K gaming over the next few years.

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 1429.1% 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 Iris Plus Graphics 645 still worth buying for gaming in 2026?

Yes. Iris Plus Graphics 645 is still a strong modern gaming GPU: it is still fine for 1080p, but 1440p and especially 4K require more compromise. 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.
