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.
Price & Value
The Arc B570 currently lists from $242 GBP, $37 GBP less than the Arc A580 at $279 GBP. Despite being slower, the Arc B570 offers the better performance-per-dollar (~10% better value), so budget-focused buyers should weigh it carefully. The Arc A580 still sits about $100 GBP above its $179 GBP MSRP.
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?
Choose the Arc A580 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Arc B570 stretches your money further for only slightly lower performance.
