The X1S has the deepest result set here: matched Ollama and llama.cpp CPU requests, explicit CPU and Vulkan modes, thermal data, MTP tests, compatibility failures, and retained i915 evidence.
Measured on Trevor’s X1S review unit.
Four exact Q4_K_M GGUFs received the same raw prompt, context, thread count, batch settings, sampler, and 96-token output through Ollama 0.32.1 and native llama.cpp commit 9a286ac.
Open full testQwen3 0.6B and 1.7B ran in three explicit modes with the same native binary and pp128/tg96 workload. Larger full-Vulkan models were retained as failure evidence.
Open full testThe exact 8.8 GB Bartowski IQ4_XS file from pinned revision 8be84a0 was verified before testing at three and four CPU threads.
Open full testQwen3.5 0.8B, Qwen3.5 2B, and Gemma 4 E2B ran with MTP off and on at every draft depth from one through four. Service logs proved the draft path was active.

Open full testThe exact BitCPM TQ2_0 file exposed a runtime-support difference. A separate Gemma 3 text-only derivative documented a different conversion problem before the later Vulkan failure.
Open full testSix Ollama models received the same deterministic prompt with one cold and two warm requests during the original Kali and hardware test.
