This tiny PC has two Intel Arc B70 GPUs with 64GB of RAM and water cooling — Gunnir B70 workstation runs on Intel's Ultra 200HX with no AMD version in sight

At the recent Intel Connection 2026 event in China, hardware manufacturer Gunnir unveiled two custom workstation systems built around Intel's Arc Pro B70 graphics processors. Both systems utilize Intel Core Ultra 200HX Arrow Lake-HX processors, and thus, do not include any AMD processor or graphics options. The larger system features two Arc Pro B70 cards housed within a compact enclosure, with liquid cooling to manage the heat generated by the graphics hardware.

Each Arc Pro B70 card comes equipped with 32GB of GDDR6 ECC memory, providing a total of 64GB of memory across the dual GPU configuration. However, it is important to note that this memory remains divided between the GPUs rather than forming a single 64GB pool. Intel's oneAPI framework enables computation across multiple devices, allowing compatible applications to harness several GPUs for parallel processing workloads.

The Arc Pro B70 processor is built on Intel's larger BMG-G31 Battlemage GPU, which features 32 Xe cores and 256 XMX engines capable of delivering up to 367 INT8 TOPS. Additionally, each B70 card boasts 608GB/s of memory bandwidth, applicable to both graphics processors in the larger workstation. The partner boards that house these workstations can consume power between 160W and 290W, which is a wider range than the single 230W rating Intel provides for its reference board.

Intel introduced the B70 earlier this year, with a suggested starting price of $949 for the card. However, partner versions may vary in price based on implementation. The event coverage did not disclose any shipping date, price, or release window for either workstation, leaving the cost relative to the $949 card uncertain. Intel describes the B70 as well-suited to local AI inference and workloads that can utilize multiple graphics processors simultaneously, which justifies Gunnir's experimentation with dense dual-GPU systems instead of conventional gaming desktops.
