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 400% 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 GeForce RTX 3070 Ti currently lists from $66,300 JPY, $23,172 JPY less than the Radeon RX 6400 at $89,472 JPY. Because it's both faster and competitively priced, the GeForce RTX 3070 Ti wins on performance-per-dollar by about 575%. The GeForce RTX 3070 Ti still sits about $65,701 JPY above its $599 JPY MSRP. The Radeon RX 6400 still sits about $89,313 JPY above its $159 JPY 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. Its more modern RDNA 2 architecture on a TSMC N6 process is part of why it does more with each watt.
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.
