Arc Battlemage with 12GB VRAM

Engineering samples of Intel Arc Battlemage are now being tested.

A new Arc B-Series graphics card has been spotted in boot-up information, powered by Intel’s Battlemage architecture. The graphics card features 12GB of memory, which would be a first for Intel’s desktop SKUs. It’s worth noting that Intel did launch a 12GB version, but it was only available for laptops in the form of the Arc A730M.

According to the output, the card features 19 Gbps memory , which is 3.5-1.5 Gbps faster than the Alchemist series. Assuming this card is a successor to the mid high-end Arc A7 series, that would represent an upgrade in memory speed of around 3 Gbps. However, due to the 192-bit memory bus, the actual bandwidth will be lower, at 456 GB/s compared to 512 GB/s on the previous generation.

As noted by Wccftech, the output references 14 GuC (Graphics u/micro Controller) units, which could indicate the presence of 14 Xe2-Cores on this graphics processor.

To recap, there are three known Battlemage GPUs: BMG-G31, G10, and G21. Each features a different number of Xe2-Cores: 32, 28, and 20 respectively. The fate of the G10 is currently unknown, but if Intel launches both the G31 and G21 models, there are several possible configurations to consider.

The new Battlemage architecture is expected to bring improvements in ray tracing acceleration, faster memory, and a performance boost of around 1.5x over the Xe2 (Alchemist) series. This information comes from the Lunar Lake update (compared to Meteor Lake Xe), which uses a power-optimized version called Xe-LPG for integrated graphics.
