Even more evidence has emerged to suggest that Intel is gearing up to launch a new flagship graphics card, presumably the Intel Arc B770. That detail is yet to be determined, but shipping data spotted online now points towards a 300W GPU in the works – that’s more power draw than the current flagship Intel Arc B580, an last-gen’s top A770 card, which feature 190W and 225W TDPs, respectively.

The publicly-viewable shipping data was spotted by a known hardware leaker, though their post has since been removed. However, you can still find the source online, which references a shipment that looks similar to previous Intel GPUs. In terms of current-gen hardware, the higher 300W TDP would match the power of Nvidia’s RTX 5070 Ti.

300W GPU listed in shipping data

The GPU listed in the shipping data is simply referred to as “N38341-001 TASDK 300W GPU BRKT 0.8,” and while that doesn’t seem to reveal much, similar descriptions have been sighted before, and the code’s formatting is similar to previous Intel GPUs. For example, Intel’s own Arc B580 Limited Edition card used code ‘M19826-306’ for its PCB.

Assuming this is the Arc B770, the 300W power draw would be exactly double Intel’s Arc B570, its entry-level option primarily designed for 1080p gaming. The 300W TDP lines up with previous rumors that Intel has been testing a larger desktop die for its current Battlemage ‘B-series’ generation, referred to as BMG-G31 (this codename has previously been referenced in online shipping data, too). The B770 is rumored to feature 32 Xe2 cores and 16GB of VRAM, which is an obvious step up from the B580 which packs in 20 Xe2 cores and 12GB of GDDR6 memory on a 192-bit memory bus.

Intel has technically produced a card with more than 300W power draw before, the Intel Arc Pro B60 dual-GPU, which features 200W on each GPU. While you can use this for gaming, it’s more catered for workstations, so it’s difficult to really call it a ‘gaming GPU’. In any case, Intel will be taking part at CES 2026 early next year, and we hope to hear more from its Arc graphics division.
