Arc A770 vs Arc B570: In-Depth Breakdown
Performance: Arc A770 vs Arc B570
The Arc A770 is significantly faster, around 33% ahead of the Arc B570. That gap is enough to move it up a tier: the Arc A770 is comfortable at 1440p, while the Arc B570 is better matched to 1080p. The Arc A770 packs 4,096 shading units versus 2,304 on the Arc B570.
Price & Value
Right now the Arc B570 starts at $242 GBP against $289 GBP for the Arc A770. Because it's both faster and competitively priced, the Arc A770 wins on performance-per-dollar by about 12%. The Arc A770 is trading below its $329 GBP MSRP — a genuine deal.
Power & Efficiency
The Arc B570 draws just 150W versus 225W for the Arc A770, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Battlemage architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 16GB against 10GB, the Arc A770 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Arc B570's 10GB can fall short. The Arc A770's memory is also faster — 560 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 3 years newer than the Arc A770 (Battlemage vs Alchemist), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Arc A770 or Arc B570?
The Arc A770 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 B570 if you find it at a steep discount.
