The llama.cpp and vLLM projects move INSANELY fast. do we have a good grasp on how good tensor-parallel inference on Intel Arc is at the end of Aug 2026?

As of late August 2026, the llama.cpp and vLLM projects are advancing rapidly, but community members report that the most recent information on tensor-parallel inference for Intel Arc GPUs remains a Reddit post from earlier in the year, which highlighted a merged PR for TP SYCL in llama.cpp. Users are seeking updated performance benchmarks, particularly for running Qwen3.6/8-27B on dual Arc Pro B65 GPUs, with some considering switching from two 16GB 5060Tis to gain sufficient VRAM for reasonable quantization without quantizing KV cache.
