GeForce RTX 3060 8GB vs Radeon RX 6400: In-Depth Breakdown
Performance: GeForce RTX 3060 8GB vs Radeon RX 6400
The GeForce RTX 3060 8GB is dramatically faster, around 167% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the GeForce RTX 3060 8GB is comfortable at 1080p, while the Radeon RX 6400 is better matched to entry-level 1080p.
Price & Value
Right now the Radeon RX 6400 starts at $253 EUR against $599 EUR for the GeForce RTX 3060 8GB. Because it's both faster and competitively priced, the GeForce RTX 3060 8GB wins on performance-per-dollar by about 13%. The Radeon RX 6400 still sits about $94 EUR above its $159 EUR MSRP. The GeForce RTX 3060 8GB still sits about $270 EUR above its $329 EUR MSRP.
Power & Efficiency
The Radeon RX 6400 draws just 53W versus 170W for the GeForce RTX 3060 8GB, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern RDNA 2 architecture on a TSMC N6 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 8GB against 4GB, the GeForce RTX 3060 8GB 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 3060 8GB 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 3060 8GB or Radeon RX 6400?
The GeForce RTX 3060 8GB 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.
