Running GLM 5.2 on RTX PRO 6000 server
GLM 5.2 has 744 billion parameters. RTX PRO 6000 server offers 768 GB of GDDR7 across 8 GPUs memory. This page puts the two side by side.
How much memory does GLM 5.2 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 | 1,711 GB | does not fit | full precision, the quality reference |
| FP8 | 856 GB | does not fit | negligible loss on most tasks |
| NVFP4 | 428 GB | fits | Blackwell format, native FP4 compute |
| Q4 | 428 GB | fits | block quantisation, broadly supported |
What is left to serve requests?
GLM 5.2 fits on RTX PRO 6000 server only when quantised. In NVFP4, its weights take about 428 GB of 768 GB. More precise formats do not fit. 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.
RTX PRO 6000 server ranges from 250 to 350 k€, indicative and not contractual. The machine targets the PME, GE segment.
