GUNNIR shows liquid-cooled dual Arc Pro B70 workstation with 64GB VRAM

GUNNIR has demonstrated a workstation built around two Intel Arc Pro B70 graphics cards, combining 64GB of graphics memory with liquid cooling in a dense system aimed at professional compute work.

The machine appeared at Intel Connection 2026 in China, according to VideoCardz. GUNNIR also showed a smaller Arc Pro workstation that uses vapor-chamber cooling, with both systems reportedly paired with Intel Core Ultra 200HX processors.

Two cards, not one 64GB pool

Each Arc Pro B70 carries 32GB of GDDR6 memory with error correction. The two-card system therefore has 64GB installed, but VideoCardz cautions that software does not see it as one conventional 64GB graphics card. Workloads need multi-GPU support, such as Intel's oneAPI tools, to use both devices.

Intel's B70 is based on the larger BMG-G31 Battlemage chip. The reported specifications include 32 Xe cores, 256 XMX engines, up to 367 INT8 TOPS and 608 GB/s of memory bandwidth. Intel lists a 230W reference board power, while partner designs can operate across a wider range.

GUNNIR already sells a blower-cooled Arc Pro B70 TF 32G for continuous workstation use. The liquid-cooled demonstration points toward systems that pack more of that hardware into one chassis for local AI inference and other workloads that can scale across multiple GPUs.
