Performance: Radeon RX 6600 XT vs Arc A380
The Radeon RX 6600 XT is dramatically faster, around 200% ahead of the Arc A380. That gap is enough to move it up a tier: the Radeon RX 6600 XT is comfortable at 1080p, while the Arc A380 is better matched to entry-level 1080p.
Price & Value
Right now the Arc A380 starts at $1,329 BRL against $3,135 BRL for the Radeon RX 6600 XT. Because it's both faster and competitively priced, the Radeon RX 6600 XT wins on performance-per-dollar by about 27%. The Arc A380 still sits about $1,190 BRL above its $139 BRL MSRP. The Radeon RX 6600 XT still sits about $2,756 BRL above its $379 BRL MSRP.
Power & Efficiency
The Arc A380 pulls less power (75W vs 160W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 6600 XT draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.
VRAM & Future-Proofing
With 8GB against 6GB, the Radeon RX 6600 XT has more headroom for 4K textures and memory-hungry creative/AI tasks where the Arc A380's 6GB can fall short.
Features & Ecosystem
Beyond raw numbers, the Arc A380 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 A380 or Radeon RX 6600 XT?
The Radeon RX 6600 XT 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.
