Chinese graphics card manufacturer Maxsun has announced a new dual-GPU board that places two Intel Arc B60 processors on a single PCB. The company has introduced two versions of the product — a dual-slot blower-cooled model and a single-slot liquid-cooled edition. Each version integrates a pair of Arc B60 GPUs, with each processor equipped with 24 GB of memory, bringing the total onboard capacity to 48 GB.
The design aims to serve dense AI inference and compute workstations, where maximizing performance per slot is essential. Maxsun described use cases that combine multiple boards within a single system, allowing professionals to install up to four dual-GPU cards for a combined 192 GB of video memory. This configuration supports workloads that rely on large-scale data processing or AI model training, helping local systems handle projects that would otherwise require cloud resources.
For the cooling solution, Maxsun collaborated with abee, a well-known PC cooling manufacturer, to develop a custom liquid-cooling block for the single-slot version. The blower-cooled variant, on the other hand, features a full-height shroud measuring over 30 cm in length with a lateral air exhaust design. Both models retain independent display connectivity for each GPU, offering one DisplayPort 2.1 and one HDMI 2.1b interface per processor.
Power is supplied through a 12V-2×6 pin connector rated for 600 watts, providing sufficient headroom for continuous workloads. Interestingly, Maxsun chose not to use a traditional PCI Express bridge chip. Instead, the card relies on the native PCIe 5.0 x8 host interface of the Intel BMG G21 silicon, distributing lanes directly through the x16 connector. This approach simplifies board design, enhances efficiency, and reduces latency between the two GPUs.
The company also referenced CPU-level coherency features tied to PCIe Gen 5 and CXL, elements of Intel’s Project Battlematrix, which enable improved data sharing between system components. Such features can play a crucial role in environments that depend on multi-GPU setups, allowing more consistent memory access and coordination between processing units.
Maxsun did not provide information about pricing or availability, though it noted that the dual Arc B60 board will likely be distributed through specialized workstation systems. The company suggested that W790-based motherboards, also developed by Maxsun, would be the initial platform for integration.
With its combination of compact design, high memory capacity, and focus on scalability, the dual Arc B60 solution could find a place in AI research labs, startup environments, and edge computing systems where dense compute performance is a priority.
