Arc A770 vs Arc A580: In-Depth Breakdown
Performance: Arc A770 vs Arc A580
The Arc A770 is significantly faster, around 25% ahead of the Arc A580. Both cards sit in the same broad class, well suited to 1080p. The Arc A770 packs 4,096 shading units versus 3,072 on the Arc A580. The Arc A770 also has more RT cores (32 vs 24) and more AI cores (512 vs 384), strengthening its ray-tracing and AI-upscaling performance.
Power & Efficiency
The Arc A580 sips power at 175W next to the Arc A770's 225W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU.
VRAM & Future-Proofing
The Arc A770's 16GB (vs 8GB on the Arc A580) gives it more room for 4K textures and memory-hungry creative or AI workloads. The Arc A770's memory is also faster — 560 GB/s versus 512 GB/s — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: Arc A580 or Arc A770?
The Arc A770 is the faster card by about 25%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
