GeForce RTX 4070 vs Radeon RX 6400: In-Depth Breakdown
Performance: GeForce RTX 4070 vs Radeon RX 6400
The GeForce RTX 4070 is dramatically faster, around 517% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the GeForce RTX 4070 is comfortable at 1440p, while the Radeon RX 6400 is better matched to entry-level 1080p.
Price & Value
Right now the Radeon RX 6400 starts at $180 EUR against $957 EUR for the GeForce RTX 4070. Because it's both faster and competitively priced, the GeForce RTX 4070 wins on performance-per-dollar by about 16%. The GeForce RTX 4070 still sits about $357 EUR above its $600 EUR MSRP.
Power & Efficiency
The Radeon RX 6400 pulls less power (53W vs 200W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 4070 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern Ada Lovelace architecture on a TSMC N4 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 12GB against 4GB, the GeForce RTX 4070 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6400's 4GB can fall short.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 4070 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 4070 or Radeon RX 6400?
The GeForce RTX 4070 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.
