Arc A380 vs Radeon RX 580: In-Depth Breakdown
Performance: Arc A380 vs Radeon RX 580
The Arc A380 and Radeon RX 580 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.
Price & Value
Right now the Radeon RX 580 starts at $136 EUR against $157 EUR for the Arc A380. Despite being slower, the Radeon RX 580 offers the better performance-per-dollar (~15% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 580 is trading below its $229 EUR MSRP — a genuine deal.
Power & Efficiency
The Arc A380 draws just 75W versus 185W for the Radeon RX 580, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Alchemist architecture on a TSMC N6 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 8GB against 6GB, the Radeon RX 580 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Arc A380's 6GB can fall short.
Generation & Longevity
The Arc A380 is roughly 5 years newer than the Radeon RX 580 (Alchemist vs GCN 4.0 (Polaris)), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc A380 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 580 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 A380 or Radeon RX 580?
Choose the Arc A380 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 580 stretches your money further for near-identical performance.
