Running Qwen 3.6 27B on H200 SXM server
Qwen 3.6 27B has 27 billion parameters. H200 SXM server offers 1,128 GB of HBM3e across 8 GPUs memory. This page puts the two side by side.
How much memory does Qwen 3.6 27B need?
Weights take the parameter count multiplied by the format size, plus a 15% runtime margin for activations and buffers. The attention cache sits on top: it grows with context length and with the number of concurrent requests, so it is sized case by case.
| Format | Weights in memory | On this machine | What the format costs |
|---|---|---|---|
| FP16 | 62.1 GB | fits | full precision, the quality reference |
| FP8 | 31.0 GB | fits | negligible loss on most tasks |
| NVFP4 | 15.5 GB | fits | Blackwell format, native FP4 compute |
| Q4 | 15.5 GB | fits | block quantisation, broadly supported |
What is left to serve requests?
Qwen 3.6 27B fits comfortably on H200 SXM server. In FP16, its weights take about 62.1 GB of the 1,128 GB available, leaving 1,066 GB for the attention cache and concurrency. The remaining margin decides how many concurrent requests and how much context the machine sustains. A margin below a quarter of memory forces a limit on context or on concurrency.
H200 SXM server ranges from 350 to 500 k€, indicative and not contractual. The machine targets the GE segment.
