Arc A580 vs Arc B570: In-Depth Breakdown
Performance: Arc A580 vs Arc B570
The Arc A580 is marginally faster, around 5% ahead of the Arc B570. Both cards sit in the same broad class, well suited to 1080p. The Arc A580 packs 3,072 shading units versus 2,304 on the Arc B570.
Power & Efficiency
At 150W against 175W, the Arc B570 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Battlemage architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
The Arc B570 carries 10GB versus 8GB on the Arc A580. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The Arc A580's memory is also faster — 512 GB/s versus 380 GB/s (256-bit vs 160-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Arc B570 is roughly 2 years newer than the Arc A580 (Battlemage vs Alchemist), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Arc A580 or Arc B570?
The Arc A580 is the faster card. 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.
