This machine is clearly targeted at professional users with demanding AI inference and parallel processing workloads, offering substantial graphics memory and compute power in a remarkably compact design. However, without crucial details like pricing, availability, and real-world performance benchmarks, it remains an exciting but speculative prospect. Its Intel-exclusive architecture also means no AMD alternatives are on the horizon, narrowing its appeal to those committed to Team Blue's ecosystem for workstation tasks.

Introduction: Doubling Down on Arc for Workstations

At the recent Intel Connection 2026 event in China, hardware manufacturer Gunnir unveiled a workstation that immediately caught our attention: a compact system housing not one, but two Intel Arc Pro B70 graphics processing units. Paired with Intel's latest Core Ultra 200HX Arrow Lake-HX processors, this machine, and its variants, signify a clear push by Gunnir and Intel into the professional workstation market, particularly for AI inference and complex parallel processing. What’s perhaps most notable is the complete dedication to Intel hardware – you won't find any AMD silicon here, either for the CPU or graphics.

The larger of the two systems demonstrated is a testament to engineering prowess, managing to fit these dual GPUs into a compact chassis while utilizing liquid cooling to manage the considerable heat output. For those who demand serious compute power and substantial video memory without occupying a full-size tower, the Gunnir B70 workstation presents a compelling, if currently mysterious, option.

Key Specifications and Performance Potential

At the heart of the Gunnir B70 workstation are its two Intel Arc Pro B70 graphics cards. Each of these professional-grade GPUs is built on Intel's larger BMG-G31 Battlemage GPU, featuring 32 Xe cores and 256 XMX engines, capable of delivering up to 367 INT8 TOPS of performance. When combined, this offers a substantial amount of raw compute power for compatible applications.

Memory is another key highlight. Each Arc Pro B70 card comes equipped with a generous 32GB of GDDR6 ECC (Error-Correcting Code) graphics memory. This translates to a total of 64GB of VRAM within the dual-GPU workstation. It’s important to note, however, that this 64GB is spread across two separate graphics processors, rather than being a single, unified pool. For applications that can effectively distribute workloads across multiple GPUs, this configuration offers immense potential, especially for large datasets in AI inference or scientific simulations. Intel's oneAPI framework is specifically designed to support computation across multiple devices, allowing compatible software to leverage these separate memory pools efficiently.

Each B70 card also boasts a memory bandwidth of 608GB/s, meaning the dual-GPU setup essentially doubles this potential for parallel tasks. Power consumption for partner boards like Gunnir's can range from 160W to 290W, a wider spread than Intel's reference 230W, suggesting optimization for various form factors and cooling solutions. While the B70 graphics card itself launched earlier this year with a suggested starting price of $949, the overall cost of the full workstation remains undisclosed.

Underpinning this graphics power is an Intel Core Ultra 200HX Arrow Lake-HX processor, ensuring that the CPU side of the equation is also robust enough to handle demanding professional applications.

Design, Cooling, and Workstation Variants

The Gunnir B70 workstation embraces a compact design philosophy, particularly impressive given the high-performance components it houses. The larger, dual-GPU system utilizes a sophisticated liquid cooling solution, which is crucial for maintaining optimal temperatures and sustained performance from two powerful GPUs within a limited space. This commitment to advanced cooling underscores the workstation's intent for heavy, continuous workloads.

Beyond the flagship dual-GPU model, Gunnir also showcased a smaller workstation. This variant likely features a single B70 GPU, and opts for a vapor chamber cooling system to manage thermals in an even more constrained form factor. The use of vapor chambers is a smart choice for compact, high-power systems where traditional air cooling might struggle, offering an efficient heat dissipation method without the bulk of liquid cooling reservoirs and pumps.

Further demonstrating their focus on space-saving solutions, Gunnir also presented MXM graphics modules utilizing B50 and B65 chips. These smaller, standardized form factors are ideal for embedding discrete graphics into ultra-compact systems where standard PCIe expansion cards are simply too large. While specific details on the performance, memory, or pricing of these MXM modules were not provided, their existence signals Gunnir’s broader strategy to cater to various workstation needs, from desktop-replacement-style compact PCs to embedded industrial solutions.

The inclusion of ECC memory across the Arc Pro B70 lineup, including the separately sold Gunnir Arc Pro B70 TF 32G with a blower cooler, reinforces the workstation-grade nature of these components. ECC memory is critical in professional environments where data integrity is paramount, making these systems suitable for scientific computing, financial modeling, and other error-sensitive tasks.

Comparison to Alternatives

The workstation market features a diverse range of powerful machines, and the Gunnir B70 enters a space where it will inevitably be compared to offerings from industry giants. While the source mentions several other high-end workstations like Nvidia's RTX Pro 5500 with its massive 84GB GDDR7 memory, GMKTec's Neo-X1 with a laptop CPU and desktop RTX 5070, and even supercomputers like the Asus GB300 DGX or Supermicro Gold Series GPU AI Station (costing $91,100 to $120,000), these are not direct, like-for-like alternatives to the Gunnir B70 workstation.

The comparison is challenging for several reasons: the mentioned alternatives span different architectures (Nvidia, AMD, various Intel chips), significantly different price points (from sub-$1000 GPUs to six-figure workstations), and often target varying tiers of extreme performance. For instance, the Nvidia RTX Pro 5500 is a single GPU with a unique memory configuration, and the DGX stations are enterprise-grade AI supercomputers, not compact desktop workstations.
