Arc A580 vs Radeon RX 6600: In-Depth Breakdown
Performance: Arc A580 vs Radeon RX 6600
The Arc A580 is marginally faster, around 7% ahead of the Radeon RX 6600. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
The Radeon RX 6600 currently lists from $1,870 BRL, $269 BRL less than the Arc A580 at $2,139 BRL. Despite being slower, the Radeon RX 6600 offers the better performance-per-dollar (~7% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6600 still sits about $1,540 BRL above its $330 BRL MSRP. The Arc A580 still sits about $1,960 BRL above its $179 BRL MSRP.
Power & Efficiency
At 132W against 175W, the Radeon RX 6600 is both the lower-power and the more efficient card, making it the easier build to cool and power.
Generation & Longevity
The Arc A580 is roughly 2 years newer than the Radeon RX 6600 (Alchemist vs RDNA 2), 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 6600 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 6600?
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 6600 stretches your money further for only slightly lower performance.
