Intel Arc B770 Graphics Card Expected in Laptops Following NBD Shipment Discovery

The Arc B770 has generated considerable buzz over the past few weeks, potentially marking its debut as the first Battlemage discrete GPU designed for mobile platforms if reports hold true.

Intel BMG-G31 Identified in NBD Shipment; Microsoft Surface Laptop Integration Expected

Despite the Intel BMG-G31-based GPU not being publicly launched, indications suggest it is already being incorporated into laptop designs. Recent sightings of the BMG-G31 die in NBD shipping manifests and in Compute Runtime have confirmed the GPU’s development status. While the final product name remains unofficial, it is speculated to succeed the Arc A770 and could be branded as the Arc “B770”.

Currently, the leading GPUs based on the Xe2 architecture, such as those utilizing the BMG-G21 die found in the Arc B580 and B570, set the pace in performance. The upcoming Arc B770 will leverage the BMG-G31 die, which, although similarly sized, is expected to feature an increased number of shaders. The recent NBD shipping manifest indicates this new die is being tested in mobile hardware, specifically with the Microsoft Surface 7, which is renowned for its slim and lightweight design.

The latest iterations of the Surface 7 laptops primarily utilize Snapdragon X Plus and X Elite processors, typically lacking discrete GPUs. However, the introduction of Lunar Lake chips suggests that the Surface 7 line may evolve to feature Xe2-based GPUs, thereby integrating a discrete GPU, which would be a remarkable shift. If the reports are accurate, this would position the Arc B770 as the inaugural and potentially the most powerful Battlemage discrete GPU in laptop form—an unprecedented development since no other Battlemage Arc B series GPUs have yet been utilized in mobile platforms, especially those traditionally without discrete graphics solutions.

As intriguing as the Arc B770 may seem for mobile applications, it faces a significant challenge due to the dominance of NVIDIA’s 60 and 70-class mobile GPUs within the gaming laptop market. Regarding specifications, the B770 is anticipated to feature 32 Xe2 cores along with 16 GB of GDDR6 VRAM and a 256-bit memory interface. While its performance against competing NVIDIA or AMD GPUs remains to be seen, initial expectations suggest it could surpass the Arc B580 and possibly rival the RTX 5060 Ti or RX 9060 XT in terms of gaming capabilities.
