Quick Answers

So, is GeForce RTX 4070 better than Radeon RX 6400?

Yes. GeForce RTX 4070 is clearly the better overall GPU here. You are also looking at 26,919 vs 7,728 in G3D Mark. On top of that, GeForce RTX 4070 is a 2023 card with DLSS 3.5 + Frame Generation, while Radeon RX 6400 is a 2022 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 2022, 248.3% 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 about 276.7% more expensive on MSRP at $599 MSRP versus $159 MSRP, and you are getting 248.3% higher G3D Mark. Radeon RX 6400 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium. If you are comfortable paying the premium for the stronger gaming result, GeForce RTX 4070 is the one to buy. If staying closer to budget matters more, Radeon RX 6400 still makes more sense on price alone and remains capable enough for modern gaming.

Is Radeon RX 6400 still worth buying for gaming in 2026?

Yes. Radeon RX 6400 is still a strong gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. This mostly comes down to price. If you want to stay closer to $159 MSRP, it remains a strong choice; if you are comfortable paying more, GeForce RTX 4070 earns that extra money with a clearly stronger gaming result and a more complete overall package.
