Arc B580 vs Arc A750: In-Depth Breakdown
Performance: Arc B580 vs Arc A750
The Arc B580 is significantly faster, around 22% ahead of the Arc A750. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
The Arc B580 currently lists from $1,636 BRL, $625 BRL less than the Arc A750 at $2,262 BRL. Because it's both faster and competitively priced, the Arc B580 wins on performance-per-dollar by about 69%. The Arc B580 still sits about $1,388 BRL above its $248 BRL MSRP. The Arc A750 still sits about $1,973 BRL above its $289 BRL MSRP.
Power & Efficiency
At 190W against 225W, the Arc B580 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 B580 carries 12GB versus 8GB on the Arc A750. The extra 4GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The Arc A750's memory is also faster — 512 GB/s versus 456 GB/s (256-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Arc B580 is roughly 2 years newer than the Arc A750 (Battlemage vs Alchemist), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Arc A750 or Arc B580?
The Arc B580 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 A750 if you find it at a steep discount.
