Arc A750 vs Arc B580: In-Depth Breakdown
Performance: Arc A750 vs Arc B580
The Arc A750 is noticeably faster, around 8% ahead of the Arc B580. That gap is enough to move it up a tier: the Arc A750 is comfortable at 1440p, while the Arc B580 is better matched to 1080p. The Arc A750 packs 3,584 shading units versus 2,560 on the Arc B580.
Price & Value
The Arc A750 currently lists from $202 GBP, $87 GBP less than the Arc B580 at $289 GBP. Because it's both faster and competitively priced, the Arc A750 wins on performance-per-dollar by about 55%. The Arc A750 is trading below its $289 GBP MSRP — a genuine deal.
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 A750 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 B580 if you find it at a steep discount.
