Intel's upcoming Arc B770 discrete GPU leaks out on GitHub, launch appears imminent — Reportedly featuring the BMG-G31 GPU, 16GB+ VRAM, 32 Xe2 cores, and 300W TDP

Rumors of a successor to Intel's Arc A770 discrete GPU have been floating around for more than a year at this point, with a new launch window finally seeming on the horizon. Following various leaks, the Arc B770, has just appeared on an undisclosed Intel GitHub repository, with code specifically mentioning "b770." While this isn't an official confirmation, it's easy to connect the dots and see the B770 is closer than ever.

Arc B770 will be part of Intel's second-gen discrete GPU architecture known as "Battlemage," using Xe2 cores, which was supposed to be a lot more ambitious at one point, but the plans seem to have dwindled. Right now, Intel has moved on to Xe3 cores in its Panther Lake mobile chips, though that's still classified as Battlemage (and not Celestial).

Anyhow, prior leaks have revealed some of the specs we can expect in the B770, including the large BMG-G31 die it uses, featuring 32 Xe2 cores. That's a big jump from the 20 Xe cores found on the last-gen A770. The GPU will also feature at least 16GB of GDDR6 VRAM saturated across a 256-bit wide bus. While some rumors point toward more than 16, it's highly unlikely now given the DRAM shortage the industry has plunged into.

The card will compete with AMD's RX 9060-class and Nvidia's RTX 5060-class offerings, with a reported TGP of up to 300W. There's no info on clock speeds, but we know it will be fabricated using TSMC's N5 process, since that's what other Battlemage GPUs use. Intel has also made strides with its driver suite since the last time we saw a B-series card be revealed, which was the B570 at CES 2025, one year ago.

In the past few months, the company has launched workstation-grade offerings under the Xe2 family: Arc Pro B50 and B60, but we haven't seen any new gaming GPUs. On the software side, there are rumors about an in-house multi-frame generation tech in the works at Intel, which could coincide with the launch of the Arc B770.

The timing makes sense since CES 2026 is set to open its doors in just two days - and Intel has a conference scheduled. The arrival of Arc B770 will lend some much-needed competition to Nvidia and AMD in the midrange GPU segment. Of course, it needs to be priced right, but given Intel's track record with Alchemist, it's not unreasonable to get your hopes up.
