Arc A580 vs Radeon RX Vega 64: In-Depth Breakdown
Performance: Arc A580 vs Radeon RX Vega 64
The Arc A580 is noticeably faster, around 14% ahead of the Radeon RX Vega 64. Both cards sit in the same broad class, well suited to 1080p.
Power & Efficiency
Power draw favors the Arc A580 (175W vs 295W), and it's the more efficient card too, so it's the easy pick if thermals or a smaller PSU matter. Its more modern Alchemist architecture on a TSMC N6 process is part of why it does more with each watt.
Generation & Longevity
The Arc A580 is roughly 6 years newer than the Radeon RX Vega 64 (Alchemist vs GCN 5.0 (Vega)), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc A580 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX Vega 64 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 Vega 64?
The Arc A580 is the faster card by about 14%. 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.
