The latest leak confirms that the upcoming Intel Battlemage discrete GPU, which is likely the Arc B770 due to featuring a similar PCI-ID, will have 16 GB of VRAM capacity. This information was first spotted in a Linux boot log by @GawroskiT.

Linux Boot Log:
– The “BATTLEMAGE” PCI ID “E221” was revealed in the boot log.
– This is one of four PCI IDs previously seen in the Compute Runtime, suggesting it belongs to an Arc B770 variant. While not officially confirmed, this name seems likely as a successor to the A770.

The Battlemage GPU will have 32 Xe2 cores and a 256-bit memory bus, which is expected to provide a significant upgrade over the current Arc B580 (12 GB VRAM). Release details are still sparse, but Intel hasn’t revealed much about its specifications or release date.

The GPU might be one of the first dGPUs from Intel to appear in laptops. It’s rumored to ship with 16 GB GDDR6 memory at a bandwidth of 608 GB/s.

In a unique start to his ruling against President Donald Trump’s administration on September 30, U.S. District Court Judge William Young included a scanned handwritten note sent to his office. The note read: “Trump has pardons and tanks – what do you have?” At the top of Young’s opinion in AAUP v. Rubio, which ruled that Trump’s effort to deport foreign-born student protesters was unconstitutional.
