Radeon RX 570 vs Radeon RX 6400: In-Depth Breakdown
Performance: Radeon RX 570 vs Radeon RX 6400
The Radeon RX 570 is noticeably faster, around 14% ahead of the Radeon RX 6400. Both cards sit in the same broad class, well suited to entry-level 1080p. The Radeon RX 570 packs 2,048 stream processors versus 768 on the Radeon RX 6400.
Power & Efficiency
At 53W against 150W, 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.
Memory & Bandwidth
The Radeon RX 570's memory is faster — 224 GB/s versus 128 GB/s (256-bit vs 64-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 6400 is roughly 5 years newer than the Radeon RX 570 (RDNA 2 vs GCN 4.0 (Polaris)), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 570 or Radeon RX 6400?
