Intel has announced the Arc Pro B70 and Arc Pro B65 graphics cards for advanced Artificial Intelligence compute workloads on workstations and professional visualization. The two primarily target local inferencing, software development, and deployments in multi-GPU configurations for rack scale Artificial Intelligence GPU compute acceleration. The Arc Pro B70 stands out as the most powerful discrete GPU based on Intel Xe2 Battlemage graphics architecture, with 32 Xe cores and a 256-bit wide GDDR6 interface.
The Intel Arc Pro B70 is configured with 32 Xe cores (Xe2-HPG), 256 XMX engines, and 32 Ray Tracing Units. It comes with 32 GB of GDDR6 memory across a 256-bit wide memory interface, with 608 GB/s of bandwidth on tap. The card comes with a PCI-Express 5.0 x16 host interface. The Arc B70 offers a peak throughput of 367 TOPS (INT8).
On the graphics side, it supports DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.3. Compute APIs include Intel’s own oneAPI, OpenCL 3.0, and OpenVINO. Its media engine supports AV1, HEVC, VP9, and H.265 hardware-accelerated encode and decode. Display outputs include four DisplayPort 2.1 ports.
The card comes with power draw ranging between 160 W to 290 W depending on partner implementation (230 W for the Intel reference card). Intel will provide certified drivers for Windows 11, Windows 10, and Linux. Compared with the Arc B580 gaming GPU, which comes with 24 Xe cores and a 192-bit interface, the Arc Pro B70 represents a higher-end configuration built to fully utilize the silicon in this family.
