Intel Unveils Arc Pro B70 and B65 GPUs: Tailored for AI and Professional Workstations

Intel has expanded its Arc Pro B-Series with the launch of the Arc Pro B70 and Arc Pro B65 graphics processing units (GPUs). These workstation-grade cards, based on the "Battlemage" microarchitecture and manufactured using TSMC N5 process technology, are specifically engineered for compute-intensive AI workloads and professional content creation.

Both models feature the BMG-G31 chip, with the B70 utilizing the full configuration and the B65 offering a modified version. Key characteristics include significant memory capacity and specialized AI engines, aiming to meet the demands of modern AI and professional applications.

Intel Arc Pro B70 Overview

The Arc Pro B70 incorporates the full BMG-G31 GPU, marking it as Intel's fastest graphics processor to date.

  • 32 Ray-Tracing (RT) units
  • 256 XMX Engines for AI acceleration
  • GPU Clock Speed: 2800 MHz
• AI Performance: Up to 367 INT8 TOPS (Tera Operations Per Second)
• Memory:
  • 32 GB GDDR6 memory
  • 256-bit memory bus
  • Memory Bandwidth: 608 GB/s
• Power Consumption:
  • Intel-branded variant: 230W
  • Add-in-card (AIC) models: Ranges from 160W to 290W
• Display Outputs: Four DisplayPort 2.1 outputs
• Capabilities: Support for large AI models, accelerated content creation, scalable multi-GPU LLM Linux deployments, ray tracing, and comprehensive media engines. It supports APIs including DX12 Ultimate and OpenCL 3.0, and is compatible with Windows and Linux operating systems.

Intel's internal testing indicates that the Arc Pro B70 offers superior token throughput for AI workloads and enhanced performance with large AI models compared to Nvidia's RTX Pro 4000, attributed to its higher memory capacity.

For context, the Nvidia RTX Pro 4000 has a listed price of $1,899.

Intel Arc Pro B65 Overview

The Arc Pro B65 features a modified BMG-G31 GPU, positioned as a value-optimized solution for professional use.

• Core Specifications:
  • 20 Xe2-HPG cores
  • 2,560 Pixel Shaders
  • 20 Ray-Tracing (RT) units
  • 160 XMX Engines for AI acceleration
  • GPU Clock Speed: 2400 MHz
• AI Performance: Up to 197 INT8 TOPS
• Memory:
  • 32 GB GDDR6 memory
  • Memory Bus: 192-bit (one source indicates 256-bit)
  • Memory Bandwidth: 608 GB/s
• Power Consumption: 200W (Total Board Power - TBP)
• Capabilities: Designed for high-precision local inferencing, scalable multi-GPU deployments, and advanced software development. It is compatible with Windows 11, Windows 10, and Linux Ubuntu operating systems.

Memory and Multi-GPU Deployment

Both Arc Pro B70 and B65 cards are equipped with 32GB of GDDR6 memory, a feature noted as significant for hosting and executing larger and more complex AI models. The memory interface design contributes to improved overall performance through increased memory bandwidth.

These GPUs can be configured in arrays of two, four, or eight units within a workstation or server rack module. This configuration capability allows for queuing multiple AI models or pooling memory resources for models that exceed the capacity of a single card.

Availability and Pricing

The Intel Arc Pro B70 graphics card will be available starting March 25, 2026, with a starting price of $949 US. An alternative release date of March 31 has also been indicated for both cards.

The Intel Arc Pro B65 is scheduled for release in mid-April 2026, with pricing expected to be lower than the B70. No fixed price for the B65 has been announced, as its production and sales will be managed by OEM board partners.

Partner and Model Variations

Intel plans to sell an Intel-branded Arc Pro B70 directly. Additional versions from board partners will also be available, including:

• ARKN
• ASRock
• Gunnir
• Maxsun
• Sparkle

These partner models may feature variations in pricing due to different thermal solutions and designs. A fanless Arc Pro B70 model from Maxsun has been showcased. Power and display connections on partner cards will be determined by the respective manufacturers.

A dual-GPU version of the Arc Pro B70 is reportedly under development. The launch of these cards coincides with the release of new Intel Core Ultra 7 270K Plus and Intel Core Ultra 5 250K Plus CPUs.
