Radeon RX 6600 XT vs Arc B570: In-Depth Breakdown
Performance: Radeon RX 6600 XT vs Arc B570
The Radeon RX 6600 XT is marginally faster, around 6% ahead of the Arc B570. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
Right now the Arc B570 starts at $2,089 BRL against $3,135 BRL for the Radeon RX 6600 XT. Despite being slower, the Arc B570 offers the better performance-per-dollar (~42% better value), so budget-focused buyers should weigh it carefully. The Arc B570 still sits about $1,870 BRL above its $219 BRL MSRP. The Radeon RX 6600 XT still sits about $2,756 BRL above its $379 BRL MSRP.
Power & Efficiency
The Arc B570 draws just 150W versus 160W for the Radeon RX 6600 XT, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Battlemage architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 10GB against 8GB, the Arc B570 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6600 XT's 8GB can fall short.
Generation & Longevity
The Arc B570 is roughly 4 years newer than the Radeon RX 6600 XT (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 XT 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 XT?
Choose the Radeon RX 6600 XT if you want the most performance and can absorb the higher price. If you're optimizing for value, the Arc B570 stretches your money further for only slightly lower performance.
