GeForce RTX 3070 Ti vs Radeon RX 6400: In-Depth Breakdown

Performance: GeForce RTX 3070 Ti vs Radeon RX 6400

The GeForce RTX 3070 Ti is dramatically faster, around 343% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the GeForce RTX 3070 Ti is comfortable at 1440p, while the Radeon RX 6400 is better matched to entry-level 1080p.

Price & Value

The Radeon RX 6400 currently lists from $378, $422 less than the GeForce RTX 3070 Ti at $800. Because it's both faster and competitively priced, the GeForce RTX 3070 Ti wins on performance-per-dollar by about 109%. The Radeon RX 6400 still sits about $219 above its $159 MSRP. The GeForce RTX 3070 Ti still sits about $201 above its $599 MSRP.

Power & Efficiency

At 53W against 290W, the Radeon RX 6400 is both the lower-power and the more efficient card, making it the easier build to cool and power.

VRAM & Future-Proofing

The GeForce RTX 3070 Ti carries 8GB versus 4GB on the Radeon RX 6400. The extra 4GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.

Features & Ecosystem

Beyond raw numbers, the GeForce RTX 3070 Ti brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6400 offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.

Which should you buy: GeForce RTX 3070 Ti or Radeon RX 6400?

the GeForce RTX 3070 Ti is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon RX 6400 if you find it at a steep discount.

Frequently Asked Questions

Is the GeForce RTX 3070 Ti better than the Radeon RX 6400?
