Radeon RX 590 vs Arc A380: In-Depth Breakdown
Performance: Radeon RX 590 vs Arc A380
The Radeon RX 590 is noticeably faster, around 17% ahead of the Arc A380. Both cards sit in the same broad class, well suited to entry-level 1080p.
Price & Value
The Arc A380 currently lists from $28,512 JPY, $625,526 JPY less than the Radeon RX 590 at $654,038 JPY. Despite being slower, the Arc A380 offers the better performance-per-dollar (~1866% better value), so budget-focused buyers should weigh it carefully. The Arc A380 still sits about $28,373 JPY above its $139 JPY MSRP. The Radeon RX 590 still sits about $653,759 JPY above its $279 JPY MSRP.
Power & Efficiency
At 75W against 225W, the Arc A380 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Alchemist architecture on a TSMC N6 process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the Radeon RX 590 at 8GB versus 6GB on the Arc A380 β that extra 2GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work.
Generation & Longevity
The Arc A380 is roughly 4 years newer than the Radeon RX 590 (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 590 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 590?
Choose the Radeon RX 590 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Arc A380 stretches your money further for only slightly lower performance.
