Intel’s Arc B770 Might Be Used in Laptops Based on NBD Shipment

The Arc B770 has been a topic of discussion for several weeks. If reports are accurate, it will be the first discrete GPU from the Battlemage series to enter mobile platforms.

A BMG-G31-based GPU hasn’t officially launched yet, but its die, BMG-G31, has been spotted multiple times in NBD shipments and Compute Runtime. This confirms that the GPU does exist. Although the exact naming isn’t confirmed, it’s likely to be the successor of the Arc A770 and could be named Arc “B770”.

Currently, the fastest Xe2-based Battlemage GPUs use the BMG-G21 die, found in the Arc B580 and B570. The upcoming Arc B770 will likely use the larger BMG-G31 die, which is expected to have more shaders.

According to a leaked NBD shipping manifest, the BMG-G31 is reportedly being used in a mobile platform, specifically the Microsoft Surface 7. This new model usually features lightweight and thin designs without a discrete GPU. However, if true, this would be the first time a discrete Battlemage Arc B series GPU is deployed on a laptop that doesn’t typically use one.

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.

The Arc B770 could offer an interesting option for mobile platforms, with 32 Xe2 cores and 16 GB of GDDR6 VRAM using a 256-bit memory bus. While its exact performance against NVIDIA or AMD GPUs is unknown, it should be faster than the Arc B580 and can potentially compete with the RTX 5060 Ti or RX 9060 XT.

Despite the potential of this GPU, 60 and 70-class NVIDIA mobile GPUs are already dominating the gaming laptops market.
