Intel and Maxsun Unveil Dual-GPU Arc Pro B60 Graphics Card with 48GB GDDR6 for AI Workloads

Maxsun unveils Intel dual-GPU Battlemage graphics card with 48GB GDDR6 to compete with Nvidia and AMD

Intel announced the chipmaker's new Arc Pro B50 and Arc Pro B60 at Computex 2025. Maxsun has stitched two of the latter models to produce the Intel Arc Pro B60 Dual 48G Turbo, a dual-GPU solution that provides 48GB of GDDR6 memory designed to address the most challenging AI workloads. Dual-GPU graphics cards were once popular, but technological advances have made them obsolete. The last consumer-grade dual-GPU graphics card from Nvidia was likely the GeForce GTX Titan Z from 2014, while AMD's was the Radeon Pro Duo from 2016. This means it's been quite a while since chipmakers introduced a dual-GPU product for retail. Although the Arc Pro B60 may not revive the trend, it remains noteworthy since Intel's first foray into the dual-GPU market. Then again, it's an AI graphics card, not a gaming one. The Intel Arc Pro B60 Dual 48G Turbo essentially combines two Arc Pro B60 graphics cards on one board. It utilizes dual Battlemage BMG-G21 silicon, each accompanied by its own memory. The same silicon powers the Arc B580 but offers double the memory compared to the gaming counterpart. The GPU inside the Intel Arc Pro B60 Dual 48G Turbo operates according to Intel's reference specifications. It doesn't feature factory overclocks or anything of that sort. Therefore, we're looking at 20 Xe cores, 20 RT units, 160 XMX and 160 Xe vector engines, and a 2,400 MHz clock speed. The Arc Pro B60 has 24GB of GDDR6 memory clocked at 19 GBps -- the 192-bit memory interface results in a memory bandwidth of up to 456 GB/s. The biggest selling point is that the Intel Arc Pro B60 Dual 48G Turbo has 48GB of total memory, 50% more than the GeForce RTX 5090 and matching that of the RTX Pro 5000 Blackwell or the Radeon Pro W7900. With 48GB on one Intel Arc Pro B60 Dual 48G Turbo, users can have multiple graphics cards in a single system to scale the capacity. For example, Intel had a system with two, totaling 96GB, on display. With the correct motherboard, you can easily have four installed for 192 GB. The Intel Arc Pro B60 Dual 48G Turbo is designed to fit into a standard PCIe 5.0 x16 expansion slot; however, there is a catch. Each Arc Pro B60 interacts with your system independently through a bifurcated PCIe 5.0 x8 interface. Thus, it's important to note that the motherboard must support PCIe bifurcation for the PCIe 5.0 slot hosting the Intel Arc Pro B60 Dual 48G Turbo. Like your typical AI or workstation graphics cards, the Intel Arc Pro B60 Dual 48G Turbo has a blower-type design and occupies two PCI slots. Maxsun has implemented a full-cover vapor chamber for cooling the graphics card's components and an additional metal backplate to help with heat dissipation. The graphics card is 11.8 inches (300mm) in length, so it fits inside the workstation territory, which normally spans from 10.5 to 12 inches. The TDP for the Arc Pro B60 varies between 120W and 200W, depending on the partner design. In Maxsun's case, the company has specified a total TDP of 400W, meaning one Arc Pro B60 is rated for 200W. For the same reason, the manufacturer has implemented a single 12VHWPR power connector for up to 600W. Each Arc Pro B60 GPU has one DisplayPort 2.1 output with UHBR20 support and one HDMI 2.01a port. Since there are two of them, the graphics card offers two of each. Regarding resolution support, the maximum is either 8K (7680x4320) at 60 Hz or 4K (3840x2160) at 240 Hz. Maxsun didn't reveal when or for how much the Intel Arc Pro B60 Dual 48G Turbo will be available for purchase. The Arc Pro B60 costs approximately $500 per unit, so Maxsun's AI graphics card could reasonably retail for around $1,000.

I'm actually jealous of the workstation that gets to use this Maxsun graphics card containing two Intel Arc GPUs and 48 GB of VRAM

Dual-GPU cards might be dead for gaming but they're alive and well for AI inference. Two GPUs on a single graphics card... now where have I heard this one before? Intel and its partner Maxsun have stuffed two of its new Arc Pro B60 chips onto a single GPU, and yes, it's for AI. If you're a PC gamer of a certain age, you may remember a few choice graphics cards that were made up of, more or less, two graphics cards on a single PCB, like the AMD Radeon R9 295X2. These contained all the components required to run the chips practically independently of one another, using drivers to combine their power to render a game. These cards are long-extinct now, due to a lack of the necessary Crossfire/SLI support and companies favouring large single GPUs instead. This new Intel and Maxsun dual-GPU card is bringing this concept back, sort of. The Maxsun dual-GPU card combines two Arc Pro B60 cards into a single relatively slim shroud. Slim considering it's a dual-GPU card, anyways. It's a bit of a beast for VRAM capacity, as each GPU has access to 24 GB of memory, making for 48 GB total per card. That's 96 GB for a two-card system, which is exactly what Intel was showing off over at Computex 2025. Intel showed off the Maxsun card in an inference machine, alongside a XEON CPU. It was running an AI model locally -- these models are huge and easily swallow up most gaming card's VRAM capacity -- but what was more impressive was the fact it only had two physical cards in the system. It was sat alongside another system using four, and both shared 96 GB of RAM. Unfortunately I couldn't peek the temps but I suspect those dual-GPU cards require decent cooling. The Pro B60 is a new arrival into the workstation lineup for Intel, alongside the B50. It's made up of a G21 GPU, the same found in the Arc B580, but with double the memory attached using the clamshell method also used on the RTX 5060 Ti 16 GB variant. That means 24 GB memory, 456 GB/s bandwidth, 20 Xe-cores, and a 120-200 W TBP. Oh and to run both GPUs over a single PCI slot, a x16 PCIe 5.0 connection is bifurcated into two x8 connections, which is ample enough bandwidth. Speaking to Intel at Computex 2025, I can confirm there is no 24 GB variant planned for gamers. There's just no real benefit for gamers with this configuration, I'm told. It's only for AI, folks. Will we ever see a return to dual-card configurations for gaming? Not unless someone figures out a way to have the two cards appear as one without a large amount of driver development work. That was the thorn in previous efforts with Crossfire and SLI, which saw AMD and Nvidia valiantly try to get dual-card systems working smoothly in many games and often still end up with shaky experience. All the major GPU companies would undoubtedly like to find the perfect, driver-free solution, but we're not at a loss for performance with the largest individual GPUs around today and I doubt its development is high on the priorities list.
