Overview

• Listings in an NBD shipping database reference packaging for “G31/C32,” with box dimensions similar to those seen shortly before the Arc B580 reached retail.
• Reports characterize BMG‑G31 as the likely basis for an Arc B770 card with 32 Xe2 cores, 16GB of VRAM, and a 256‑bit memory bus, although specifications remain unannounced.
• The same G31 identifier previously appeared in Intel’s Compute Runtime with four device IDs, adding to the leak trail for a larger Battlemage die.
• Observers note that B580 packaging surfaced about 2.5 months before launch and speculate a comparable window here, but timing is unverified.
• Analysts caution that a bigger die could raise manufacturing costs and complicate pricing even if performance lands near RTX 4070–5070 territory, which will depend on clocks and driver maturity.
