Radeon RX 570 vs Radeon RX 6400: In-Depth Breakdown
Performance: Radeon RX 570 vs Radeon RX 6400
The Radeon RX 570 and Radeon RX 6400 post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to entry-level 1080p gaming. The Radeon RX 570 packs 2,048 stream processors versus 768 on the Radeon RX 6400.
Price & Value
Pricing has the Radeon RX 570 at $95 USD, $83 USD under the Radeon RX 6400's $178 USD. Because it's both faster and competitively priced, the Radeon RX 570 wins on performance-per-dollar by about 87%. The Radeon RX 570 is trading below its $169 USD MSRP — a genuine deal.
Power & Efficiency
Power draw favors the Radeon RX 6400 (53W vs 150W), and it's the more efficient card too, so it's the easy pick if thermals or a smaller PSU matter. 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?
The Radeon RX 570 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.
