Radeon RX 580 vs Arc A380: In-Depth Breakdown
Performance: Radeon RX 580 vs Arc A380
The Radeon RX 580 and Arc A380 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.
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 Radeon RX 580 brings AMD FSR upscaling and strong rasterization value, while the Arc A380 offers Intel XeSS upscaling and AV1 encoding. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: Radeon RX 580 or Arc A380?
The Radeon RX 580 is the faster card. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
