Intel Arc “Battlemage” BMG-G31 B770 GPU Support Lands in Mesa Driver

Intel has quietly submitted its patches for BMG-G31 GPU SKUs in the Mesa open-source graphics driver library. With IDs e220, e221, e222, and e223, Intel is gearing up the launch of its higher-end “Battlemage” B770. In the weeks leading up to Computex 2025, Intel dropped hints and unofficial leaks about new Arc Xe2 “Battlemage” desktop graphics cards, including rumors of a high-end B770 model and placeholder mentions of a B750 on Intel Japan’s website. Fans were excited, but at the Taipei Nangang show, neither card appeared. Then Tweakers.net reported, based on unnamed insiders, that the Battlemage-based Arc B770 is real and expected to launch in November 2025, though plans could still change.

With 32 Xe2 cores for the B770, Intel plans to pair 16 GB of GDDR6 memory on a 256-bit bus. What is interesting is that Intel will use a PCIe 5.0 ×16 host bus, whereas the lower-end Arc B580 and Arc B570 use a PCIe 4.0 ×8 host bus. A faster PCIe standard is likely to follow as the higher-end Arc B770 yields significantly more compute bandwidth, so we will have to wait and see what Intel has prepared. If the rumored Q4 launch manifests, it will give gamers an interesting choice right around the holidays.
