Intel Arc Pro B70 32GB vs AMD Radeon AI PRO R9700 32GB

Side-by-side local AI comparison — VRAM, memory bandwidth, model compatibility, and estimated tokens per second across 87 open-weight models.

Quick verdict

AMD Radeon AI PRO R9700 32GB wins for local AI inference. It has 5% more memory bandwidth, runs 49 models natively (vs 49), and exclusively fits 0 models the other cannot. Note: Intel Arc Pro B70 32GB uses VULKAN while AMD Radeon AI PRO R9700 32GB uses ROCM — software ecosystem matters for your framework.

Analysis

The Intel Arc Pro B70 and AMD Radeon AI PRO R9700 both launched as 32GB workstation cards built for local AI inference, seven months apart. The R9700 came first, at $1,299; this card followed in March 2026 at $949, $350 (27%) less. Same VRAM ceiling, different vendor, different price, so the real question is what that $350 actually buys.

Both cards share an identical 32GB of VRAM, so both fit the exact same 49 of this site's 87 tracked models natively at 8k context; capacity, not bandwidth, decides that boundary, and here the two are tied. Bandwidth is where they actually differ: the R9700's 640 GB/s beats this card's 608 GB/s by 5.3%, and this site's calculator shows that gap tracking almost exactly into decode speed on every model both cards fit. Qwen 3.6 27B at Q6 runs 17.4 tok/s on the Arc Pro B70 versus 18.3 tok/s on the R9700; Llama 3.1 8B at Q4 runs 66.5 tok/s versus 70.0 tok/s, both within a few tenths of a point of that same 5.3% ratio. Software is the sharper divide: the R9700 needs ROCm 6.4.1 or newer (7.x recommended), Linux-only for GPU acceleration, validated on a narrow list of distros. The B70's Vulkan backend in llama.cpp works out of the box on both Linux and Windows, with a SYCL backend and an emerging OpenVINO path as alternatives.

Bottom line: At $350 less, the Arc Pro B70 gives up a real but modest 5.3% decode speed for identical model compatibility and a simpler, more portable software stack. Unless ROCm's ecosystem or a specific AMD software dependency already anchors your workflow, the B70's price and driver simplicity make it the easier default at this capacity tier. The R9700's advantage is a small, consistent speed edge, not a wider set of models it can run.
