Trade-offs

❌Lower PassMark G3D performance (2,172 vs 26,919).
❌Less VRAM, with 4 GB vs 12 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on FSR 3 (2023) instead.
❌Limited future-proofing: older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in upcoming AAA games.
❌Lower G3D Mark per dollar, at 13.7 vs 44.9 G3D/$ ($159 MSRP vs $599 MSRP).

Quick Answers

So, is GeForce RTX 4070 better than Radeon RX 640?

Yes. GeForce RTX 4070 is clearly the better overall GPU here. You are also looking at 26,919 vs 2,172 in G3D Mark. On top of that, GeForce RTX 4070 is a 2023 card with DLSS 3.5 + Frame Generation, while Radeon RX 640 is a 2019 model from an older generation with FSR 3 + AFMF. 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 2019, 1139.4% more raw performance headroom, more VRAM at 12 GB instead of 4 GB, and the stronger feature stack with DLSS 3.5 + Frame Generation instead of FSR 3 + AFMF. 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 4070 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. GeForce RTX 4070 is about 276.7% more expensive on MSRP at $599 MSRP versus $159 MSRP, and you are getting 1139.4% higher G3D Mark. It also leads G3D-per-dollar by 229%. That is why the better overall card still comes out as the smarter buy today, not just the faster one.

Is Radeon RX 640 still worth buying for gaming in 2026?

Yes. Radeon RX 640 is still a strong modern gaming GPU: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It remains a good buy when you can get it meaningfully cheaper than the alternative around $159 MSRP, even if GeForce RTX 4070 is still the cleaner recommendation on overall value today.
