At Computex 2025, Intel revealed the Arc Pro B50 and B60 GPUs. Maxsun then combined two B60s into the Arc Pro B60 Dual 48G Turbo, a dual-GPU card with 48GB GDDR6 for AI tasks, supporting models like DeepSeek-r1:70B. It offers PyTorch, Intel ISV, IPEX-LLM, and vLLM compatibility on bifurcated PCIe 5.0 x16 consumer platforms. A triple-layer cooler ensures sustained performance in its dual-slot design. Featuring dual Battlemage GPUs with reference specs (20 Xe cores, 2400 MHz), it provides 456 GB/s bandwidth per GPU and dual DisplayPort 2.1/HDMI 2.01a outputs. It is priced around $1,000; release is pending.
At Computex 2025, Intel introduced its new Arc Pro B50 and Arc Pro B60 GPUs. Subsequently, Guangzhou, China-based Maxsun, has combined two Arc Pro B60 models to create the Intel Arc Pro B60 Dual 48G Turbo. This product represents a dual-GPU configuration providing a total of 48GB of GDDR6 memory, a capacity intended to address demanding artificial intelligence processing tasks.
The AIB accommodates models such as the compressed and optimized version of DeepSeek-r1:70B, which has a minimum memory requirement of 43GB. This substantial memory capacity aids in the reduction of performance limitations, facilitating extended context management, a high degree of concurrent operations, and consistent output in conversations involving multiple turns.
The Arc Pro B60 Dual 48G Turbo also offers compatibility with PyTorch, Intel Independent Software Vendor certifications, the IPEX-LLM inference engine, and vLLM frameworks. This broad compatibility makes it a useful option for various artificial intelligence development applications.
The AIB employs PCIe 5.0 x8 + x8 interfaces and, Maxsun says, operates effectively on consumer-grade platforms that support PCIe x16 lane bifurcation. A number of Maxsun motherboards already incorporate this feature, enabling users to access the complete dual-GPU performance without the necessity of an enterprise-level platform. This capability contributes to a noticeable decrease in the expenses associated with system deployment.
To maintain consistent performance during prolonged periods of high operational demand, the AIB features a cooling system with three layers. This system includes a turbo-style blower fan for airflow, a large vapor chamber heat plate for thermal transfer, and a full-cover metal backplate to assist in heat dissipation. The AIB’s design occupies two PCI expansion slots in width, says Maxsun, and also permits stable configurations with multiple graphics AIBs for professional computing environments.
The Intel Arc Pro B60 Dual 48G Turbo functions by integrating two individual Arc Pro B60 graphics AIBs onto a unified circuit board. It incorporates two Battlemage BMG-G21 GPUs, each with a dedicated memory subsystem. The GPUs operate within the Intel Arc Pro B60 reference specifications and do not include any factory pre-configured performance enhancements or similar features. Consequently, the specifications include 20 Xe cores, 20 ray-tracing units, 160 XMX engines, 160 Xe vector engines, and an operating clock speed of 2,400 MHz. Each individual Arc Pro B60 unit is equipped with 24GB of GDDR6 memory operating at a speed of 19 GB/s. This memory, connected via a 192-bit interface, results in a maximum memory bandwidth of 456 GB/s per GPU. A primary advantage of the Intel Arc Pro B60 Dual 48G Turbo is its total memory capacity of 48GB. This amount exceeds the memory capacity of the GeForce RTX 5090 by 50 percent and matches the memory offered by the RTX Pro 5000 Blackwell and the Radeon Pro W7900.
The 48GB of memory available on a single Intel Arc Pro B60 Dual 48G Turbo allows users to install multiple AIBs within a single computer system to increase the overall memory capacity. Intel showed a workstation reference design that allowed multiple AIBs. As an illustration, Intel showcased its Battlematrix system containing two of these AIBs, resulting in a total of 96GB of graphics memory. Given a compatible motherboard, it is feasible to install up to four of these AIBs, achieving a total of 192GB of graphics memory.
Graphics AIBs incorporating two graphics processing units on a single printed circuit board once held a significant position in the market. However, progress in hardware technology has diminished their prevalence. The last dual-GPU graphics AIB aimed at the consumer market from Nvidia was the GeForce GTX Titan Z, introduced in 2014, while AMD’s comparable offering was the Radeon Pro Duo, which was released in 2016, almost a decade ago. While the introduction of the Arc Pro B60 may not signify a resurgence of this design trend, it remains a notable development as Intel’s initial entry into the dual-GPU product segment. Also, this product is positioned for the workstation and AI segment, not for gaming applications.
The Intel Arc Pro B60 Dual 48G Turbo is engineered to be compatible with a standard PCIe 5.0 x16 expansion slot found in many modern computer systems. However, a specific requirement exists for proper operation. Each of the two Arc Pro B60 GPUs communicates with the system independently through a PCIe 5.0 x8 interface. Therefore, it is important to verify that the motherboard in which the Intel Arc Pro B60 Dual 48G Turbo is installed supports PCIe bifurcation for the designated PCIe 5.0 slot.
The physical length of the graphics AIB is 11.8 inches (300mm), placing it within the typical size range for workstation-class graphics AIBs, which generally measure between 10.5 and 12 inches in length.
The Thermal Design Power (TDP) for an individual Arc Pro B60 unit can vary between 120W and 200W, depending on the specific design implemented by the manufacturing partner. In the case of Maxsun’s implementation of the dual-GPU AIB, the company has specified a total TDP of 400W, indicating that each of the two Arc Pro B60 GPUs is rated for a power consumption of 200W. To accommodate this power requirement, the manufacturer has included a single 12VHPWR power connector, capable of supplying up to 600W of power.
Each individual Arc Pro B60 AIB features one DisplayPort 2.1 output with UHBR20 compatibility and one HDMI 2.01a port. As the Intel Arc Pro B60 Dual 48G Turbo incorporates two such GPUs, the AIB provides a total of two DisplayPort 2.1 outputs and two HDMI 2.01a ports. Regarding display resolution support, the maximum supported resolution is either 8K (7680 x 4320 pixels) at a refresh rate of 60 Hz or 4K (3840 x 2160 pixels) at a refresh rate of 240 Hz.
Maxsun has not yet disclosed the specific time frame for when the Intel Arc Pro B60 Dual 48G Turbo will become available for purchase, nor has the company announced its intended retail price. Given that the individual Arc Pro B60 units are priced at approximately $500 each, it is reasonable to anticipate that Maxsun’s artificial intelligence-focused graphics AIB could be priced in the vicinity of $1,000.
