Arc B570 vs Radeon RX 6600: In-Depth Breakdown
Performance: Arc B570 vs Radeon RX 6600
The Arc B570 is noticeably faster, around 13% ahead of the Radeon RX 6600. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
Pricing has the Radeon RX 6600 at $2,186 BRL, $418 BRL under the Arc B570's $2,604 BRL. Despite being slower, the Radeon RX 6600 offers the better performance-per-dollar (~5% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6600 still sits about $1,856 BRL above its $330 BRL MSRP. The Arc B570 still sits about $2,385 BRL above its $219 BRL MSRP.
Power & Efficiency
Power draw favors the Radeon RX 6600 (132W vs 150W), and it's the more efficient card too, so it's the easy pick if thermals or a smaller PSU matter.
VRAM & Future-Proofing
The Arc B570 carries 10GB versus 8GB on the Radeon RX 6600. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Generation & Longevity
The Arc B570 is roughly 4 years newer than the Radeon RX 6600 (Battlemage vs RDNA 2), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc B570 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 B570 or Radeon RX 6600?
Choose the Arc B570 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.
