Overview
The Arc Pro B70 is Intel's largest Battlemage chip, launched in March 2026 for AI and workstation use: 32 Xe cores, 256 XMX engines, 367 TOPS of INT8 compute and 32GB of GDDR6 with ECC on a 256-bit bus at 608 GB/s. It is one of the least expensive ways to get 32GB on a single new card with a professional driver.
Intel's own card is a 230W dual-slot blower 267 mm long with one 8-pin connector, and partner boards vary in power and cooling. The pictured SPARKLE Arc Pro B70 Blower is a dual-slot blower measuring 289 x 120 x 42 mm, with a 2,800 MHz boost clock and a 12V-2x6 connector, which SPARKLE rates at 330W. All versions use PCIe 5.0 x16 and four DisplayPort 2.1 outputs, and blowers push heat out of the case, so cards can sit side by side.
For language models, 32GB holds a 32B model at 4-bit with a long context or at 6-bit, and two cards hold a 70B model at 4-bit. In StorageReview's vLLM tests it ran 7 to 26% ahead of the Arc Pro B60, though Intel's AI software is less mature than CUDA, so check support for your tools first. SPARKLE lists SR-IOV with up to seven virtual GPUs.

Questions and answers
Still unsure? Visit the help center or message us.
What power supply does the Arc Pro B70 need?
Intel doesn't publish a PSU figure. Its own card draws 230W through one 8-pin connector, and SPARKLE rates the pictured blower at 330W through a 12V-2x6 connector. Size the supply for the exact card plus the rest of the system; for one card in a typical workstation, a quality 750W unit leaves comfortable headroom.
Which local AI models fit in 32GB of VRAM?
Roughly, a 32B model at 4-bit with a long context or at 6-bit, and smaller models at 8-bit. A 70B model at 4-bit needs about 40GB, so it takes two cards.
Arc Pro B70 or Arc Pro B60?
The B70 has 32GB at 608 GB/s and 32 Xe cores against the B60's 24GB and 20 cores, and ran 7 to 26% faster in vLLM tests. The B60 costs less per card for wide multi-GPU rigs.
Can it run CUDA software?
No, CUDA is NVIDIA-only. On this card AI runs through llama.cpp (SYCL or Vulkan), vLLM and OpenVINO, so check that your tools support Intel GPUs first.
Which brand of Arc Pro B70 will I receive?
Intel sells its own card and partners such as ASRock, Gunnir, Maxsun and SPARKLE make theirs, and we picture the SPARKLE Blower. The model can vary with supply, and we confirm it with you before shipping.
