Radeon RX 6600 vs Arc A380: In-Depth Breakdown
Performance: Radeon RX 6600 vs Arc A380
The Radeon RX 6600 is dramatically faster, around 150% ahead of the Arc A380. That gap is enough to move it up a tier: the Radeon RX 6600 is comfortable at 1080p, while the Arc A380 is better matched to entry-level 1080p.
Price & Value
The Arc A380 currently lists from $1,329 BRL, $541 BRL less than the Radeon RX 6600 at $1,870 BRL. Because it's both faster and competitively priced, the Radeon RX 6600 wins on performance-per-dollar by about 78%. The Arc A380 still sits about $1,190 BRL above its $139 BRL MSRP. The Radeon RX 6600 still sits about $1,540 BRL above its $330 BRL MSRP.
Power & Efficiency
On power, the Arc A380 is the gentler choice at 75W versus 132W. The Radeon RX 6600 is more efficient per watt because it's faster, but its higher 132W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The Radeon RX 6600 carries 8GB versus 6GB on the Arc A380. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Features & Ecosystem
Beyond raw numbers, the Arc A380 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 A380 or Radeon RX 6600?
The Radeon RX 6600 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Arc A380 if you find it at a steep discount.
