Intel Arc B70 Pro and B65 Pro workstation GPUs leak ahead of March 25 launch

Intel's workstation graphics plans have been revealed through a leak showing the Arc B70 Pro and B65 Pro GPUs launching on March 25, 2025. These cards represent Intel's first public debut of "Big Battlemage" silicon, specifically designed for professional creators and AI developers who need stability over raw gaming performance.

Both workstation GPUs feature 32GB of ECC GDDR6 memory on a 256-bit bus, a significant upgrade from the existing B60's 24GB configuration. The ECC memory is crucial for professional workloads where a single bit flip could ruin hours of rendering or AI training. This memory configuration matches what workstation users expect from NVIDIA's RTX A-series and AMD's Radeon Pro cards.

Core configurations and power targets

The B70 Pro takes the flagship position with 32 Xe2 cores and a total graphics power (TGP) range of 160-290 watts. Intel's thermal design power (TBP) for the reference design sits around 230 watts, positioning it as a high-performance workstation card that balances power draw with professional capabilities.

The B65 Pro shares the same 32GB memory configuration but cuts down to 20 Xe2 cores, making it essentially a memory-focused variant of the B60 Pro. With a peak TGP of 200 watts, it targets professionals who need more VRAM headroom without the highest core count, offering a midrange option for workstation workflows.

Professional features and availability

Both cards support Intel's Pro features including DisplayPort 2.1a output and are expected to work with the company's latest workstation drivers. The GPUs will also feature third-party shroud designs, giving system builders and workstation manufacturers flexibility in their configurations.

Pricing and availability details remain unknown ahead of the March 25 launch. Intel appears to be prioritizing these professional cards before any potential gaming-focused Battlemage releases, disappointing gamers hoping for the rumored B770 consumer card.

For those seeking immediate consumer options, the Intel Arc B580 continues to be available at MSRP across various AIB partner cards, offering a gaming-focused alternative while Intel focuses on its workstation lineup.

The 32GB ECC memory configuration positions these cards competitively against existing workstation GPUs, particularly for memory-intensive tasks like 3D rendering, video editing, and AI development where data integrity is paramount.
