Intel’s Arc Pro B-Series now creates a clean local-AI capacity ladder: 16GB B50, 24GB B60, and 32GB B65 or B70. HighVRAM’s new buyer guide maps those cards to exact model-file boundaries while keeping software support and measured performance separate from specifications.
Four Intel workstation paths
- B50: 16GB GDDR6 ECC, 70W and compact two-slot reference design.
- B60: 24GB GDDR6, 456GB/s published bandwidth and 120–200W partner implementations.
- B65: 32GB GDDR6 with 20 Xe-cores and 160 XMX engines.
- B70: 32GB GDDR6 ECC with 32 Xe-cores and 256 XMX engines.

The decisive capacity boundaries
Using official Qwen2.5-32B GGUF file sizes, Q3_K_M at 15.9GB leaves an unsafe 0.1GB file-only margin on B50 but 8.1GB on B60 and 16.1GB on B65/B70. Q4_K_M at 19.9GB does not fit wholly on B50, leaves 4.1GB on B60 and 12.1GB on the 32GB cards. Q6_K at 26.9GB fits by file size only on B65/B70, with 5.1GB before runtime allocations.
Start with the hardware recommender, compare the capacity tiers, then verify the exact oneAPI, OpenVINO, SYCL or Vulkan path for your application.
