Arc A770 vs Radeon RX 6600: In-Depth Breakdown
Performance: Arc A770 vs Radeon RX 6600
The Arc A770 is significantly faster, around 33% ahead of the Radeon RX 6600. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
Right now the Radeon RX 6600 starts at $1,870 BRL against $3,102 BRL for the Arc A770. Despite being slower, the Radeon RX 6600 offers the better performance-per-dollar (~24% 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 A770 still sits about $2,773 BRL above its $329 BRL MSRP.
Power & Efficiency
The Radeon RX 6600 draws just 132W versus 225W for the Arc A770, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.
VRAM & Future-Proofing
With 16GB against 8GB, the Arc A770 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6600's 8GB can fall short.
Features & Ecosystem
Beyond raw numbers, the Arc A770 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 A770 or Radeon RX 6600?
Choose the Arc A770 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.
