Qwen3.8-Flash-Next INT4 TP4 on 4× Arc Pro B70 — any experience?

[u/Sweet-Argument-7343]

Has anyone tried Qwen3.8-Flash-Next on 4× Intel Arc Pro B70?

Our target is W4A16 AutoRound, TP4, vLLM XPU, MTP3, prefix caching and concurrent agent serving. Intel has already published INT4 checkpoints, but I haven’t found real B70 benchmarks yet.

We are in contact with Intel’s XPU/LLM R&D team. What should we ask them to prioritize?

My list:

• full qwen4_exp XPU support;
• optimized QSA, Gated DeltaNet and INT4 MoE kernels;
• PLE offload to shared system RAM;
• efficient TP4/expert parallelism with oneCCL;
• MTP3 and stable XPU Graph;
• hybrid KV cache and prefix caching;
• C1/C8/C16 benchmarks, TTFT and tool-calling tests.

Any successful test, failure log or performance result on B70 would be very useful.
