- MaxSun design revives long-abandoned dual-GPU engineering with modern cooling
- Each slim card manages 48GB of memory and two GPUs in tight spaces
- MaxSun Intel Arc Pro B60 48G Turbo Edition Enables Dense GPU Stacking Across Full PCIe 5.0 Bandwidth
Chinese graphics card maker MaxSun has unveiled a liquid-cooled version of Intel’s Arc Pro B60 that combines two GPUs in a single-slot design.
The model, dubbed “MaxSun Intel Arc Pro B60 48G Turbo Edition,” is part of a collaboration with abee, a company known for its minimalist workstation hardware.
Dual-GPU cards were once common among high-end graphics solutions, but were gradually phased out due to heat, power, and driver complexity.
A rare return of dual GPU in a thinner form
MaxSun’s decision to revisit this setup with the Arc Pro B60 stands out because it uses a liquid cooling system to manage temperatures while keeping the design in a single PCIe slot.
The redesign would allow the card to fit the seven full-speed PCIe 5.0 x16 slots on a W790 motherboard.
This makes it a potential option for dense workstations or small-scale data center setups.
Each card contains 48 GB of total VRAM, split between two GPUs which would share a PCIe 5.0 x16 interface.
However, this connection is split into 8 lanes per GPU, meaning performance will depend on how efficiently the software distributes workloads.
The setup theoretically allows users to install four of these cards per system, which equates to eight GPUs and a total of 192 GB of VRAM when fully configured.
While the setup seems powerful on paper, its actual effectiveness remains unclear, particularly in mixed AI and rendering applications.
MaxSun has not announced a release date or price for the liquid-cooled Arc Pro B60.
The company hinted that it was designed specifically for abee systems built around W790 motherboards.
This will likely limit availability to systems integrators rather than retail buyers.
There are no independent benchmarks or confirmation from Intel, so the performance and stability of this liquid-cooled dual-GPU setup remains largely theoretical.
Despite its advanced engineering, it remains to be seen whether this design will be able to overcome the scaling challenges that have made dual-GPU architectures impractical.
The Arc series has also struggled to match the driver maturity and performance stability of Nvidia and AMD hardware.
This makes this design intriguing on paper but uncertain in practice. For now, it appears to be an ambitious experiment rather than a technological breakthrough poised to reshape the use of GPUs for AI tools or modern data centers.
