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 A750 currently lists from $229 GBP, $96 GBP less than the Arc B580 at $325 GBP. Despite being slower, the Arc A750 offers the better performance-per-dollar (~16% better value), so budget-focused buyers should weigh it carefully. The Arc A750 is trading below its $289 GBP MSRP — a genuine deal. The Arc B580 still sits about $77 GBP above its $248 GBP 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
VRAM favors the Arc B580 at 12GB versus 8GB on the Arc A750 — that extra 4GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work. 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?
Choose the Arc B580 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Arc A750 stretches your money further for only slightly lower performance.
