Arc A580 vs Radeon RX 6400: In-Depth Breakdown
Performance: Arc A580 vs Radeon RX 6400
The Arc A580 is dramatically faster, around 167% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the Arc A580 is comfortable at 1080p, while the Radeon RX 6400 is better matched to entry-level 1080p.
Price & Value
The Radeon RX 6400 currently lists from $10 EUR, $215 EUR less than the Arc A580 at $225 EUR. Despite being slower, the Radeon RX 6400 offers the better performance-per-dollar (~719% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6400 is trading below its $159 EUR MSRP — a genuine deal.
Power & Efficiency
At 53W against 175W, the Radeon RX 6400 is both the lower-power and the more efficient card, making it the easier build to cool and power.
VRAM & Future-Proofing
The Arc A580 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.
Features & Ecosystem
Beyond raw numbers, the Arc A580 brings Intel XeSS upscaling and AV1 encoding, 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: Arc A580 or Radeon RX 6400?
Choose the Arc A580 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 6400 stretches your money further for only slightly lower performance.
