In OpenZeka's measurement, Qwen3.6-27B (27B parameters), served in FP8 format with vLLM and speculative decoding on 1× DGX Spark, reached a generation speed of 19.5 tok/s per request and a time to first token (TTFT) of 323 ms with a single request.
At the default speed targets (at least 20 tok/s per request, TTFT at most 1,000 ms) there is no capacity estimate for this configuration: no measured load level met them.
Notes: MTP gives 2.4x TPS improvement
