Arc A770 vs Arc A380: In-Depth Breakdown
Performance: Arc A770 vs Arc A380
The Arc A770 is dramatically faster, around 233% ahead of the Arc A380. That gap is enough to move it up a tier: the Arc A770 is comfortable at 1080p, while the Arc A380 is better matched to entry-level 1080p. The Arc A770 packs 4,096 shading units versus 1,024 on the Arc A380. The Arc A770 also has more RT cores (32 vs 8) and more AI cores (512 vs 128), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
Right now the Arc A380 starts at $1,329 BRL against $3,102 BRL for the Arc A770. Because it's both faster and competitively priced, the Arc A770 wins on performance-per-dollar by about 43%. The Arc A380 still sits about $1,190 BRL above its $139 BRL MSRP. The Arc A770 still sits about $2,773 BRL above its $329 BRL MSRP.
Power & Efficiency
The Arc A380 pulls less power (75W vs 225W), so it's the easier card to cool and the lighter load on your PSU. The faster Arc A770 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.
VRAM & Future-Proofing
With 16GB against 6GB, the Arc A770 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Arc A380's 6GB can fall short. The Arc A770's memory is also faster — 560 GB/s versus 186 GB/s (256-bit vs 96-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: Arc A380 or Arc A770?
The Arc A770 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.
