GeForce RTX 3070 vs Radeon RX 6400: In-Depth Breakdown
Performance: GeForce RTX 3070 vs Radeon RX 6400
The GeForce RTX 3070 is dramatically faster, around 350% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the GeForce RTX 3070 is comfortable at 1440p, while the Radeon RX 6400 is better matched to entry-level 1080p.
Price & Value
The GeForce RTX 3070 currently lists from $24 EUR, $156 EUR less than the Radeon RX 6400 at $180 EUR. Because it's both faster and competitively priced, the GeForce RTX 3070 wins on performance-per-dollar by about 3304%. The GeForce RTX 3070 is trading below its $499 EUR MSRP — a genuine deal.
Power & Efficiency
On power, the Radeon RX 6400 is the gentler choice at 53W versus 220W. The GeForce RTX 3070 is more efficient per watt because it's faster, but its higher 220W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The GeForce RTX 3070 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.
Generation & Longevity
The Radeon RX 6400 is roughly 2 years newer than the GeForce RTX 3070 (RDNA 2 vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 3070 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 or Radeon RX 6400?
The GeForce RTX 3070 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.
