Intel Battlemage GPUs potential discovery indicated by four new IDs in Linux Mesa graphics driver
Redefining Graphics: Intel's Battlemage B770 on the Horizon
In an exciting turn of events, Intel has added four new device IDs to the latest Linux Mesa graphics driver update. These IDs, 0xe220, 0xe221, 0xe222, and 0x223, are associated with Intel's Battlemage architecture, hinting at the potential arrival of the highly anticipated Battlemage B770 GPU.
Lasse Kärkkäinen on X, a well-known figure in the tech community, shared this discovery, pointing out the absence of any GPU die model nomenclature in these IDs, which could imply that one of the IDs might be the long-awaited Battlemage B770.
The addition of these four IDs, all sporting a vague "BMG" nomenclature, is a departure from previous Mesa PCI IDs where Intel typically included the actual GPU die name in the nomenclature. At least two of these IDs are likely to represent Intel's new Arc Pro B50 and B60 workstation cards, leaving two IDs up for interpretation.
Linux Mesa PCI IDs represent graphics hardware supported by the Mesa graphics library, which provides 3D-acceleration capabilities to Linux operating systems. Normally, GPU manufacturers publish new PCI IDs to the Mesa library before those PCI devices launch.
Recent leaks and rumors suggest that Intel is still on track to launch the B770, possibly as early as Q4. If launched, the B770 is expected to feature 32 Xe cores, a 256-bit interface, and at least 16GB or more of GDDR6/GDDR6X memory, representing a significant upgrade over the B580's 20 Xe cores and 160-bit memory interface.
These specifications, if realized, would position the B770 as a formidable mid-range competitor against AMD’s Radeon RX 9060 and Nvidia’s RTX 5060 series. While it might not reach the performance levels of the RX 9070 and RTX 5070, a best-case scenario could see it giving a good run for its money. history suggests that a trimmed-down B750 variant might follow suit if the B770 does indeed make its debut.

- Summary
The Intel Arc B770 is expected to bring a next-gen Xe2 architecture, offering enhanced memory and display technology, as well as improved support for modern gaming and content creation workflows. The exact device IDs for the B770 remain uncertain, but 0xe220, 0xe221, 0xe222, and 0xe223 are potential contenders for this GPU and related variants.
- The teased IDs associated with Intel's Battlemage architecture, such as 0xe220, 0xe221, 0xe222, and 0xe223, could potentially be linked to the highly anticipated mid-range GPU, the Battlemage B770, which is rumored to feature artificial-intelligence capabilities, thanks to its Xe2 architecture.
- If the Battlemage B770 indeed materializes, it is projected to usher in a new era of technology by introducing gadgets like gaming laptops and workstations with a formidable 32 Xe cores, 256-bit memory interface, and Artificial Intelligence capabilities, making it a strong competitor in the market against the AMD’s Radeon RX 9060 and Nvidia’s RTX 5060 series.
