Your build
estimate — final price on enquiryCheck a model against our machines before you buy.
Pick the model and quantisation you plan to run. We'll show whether it fits in memory, how much room is left for context, and the throughput to expect. Estimates come from memory bandwidth and are replaced by our own bench figures where we have them.
Machine
Quantisation
Comfortable. 70 GB spare — room for 128k context, a second small model, or a RAG index in memory. Expect roughly 3.8 tok/s single-stream.
Machines that run this configuration
Weights 42.8 GB at 4.85 bits/param · KV cache 5.0 GB at 16k (fp16, approximate) · 10 GB reserved for OS and runtime. Speed is single-stream decode, memory-bound; prompt processing and batching behave differently. Members: £5,099 on this machine. Or WhatsApp an engineer on +44 7515 356 146.
An NVIDIA-Certified HGX B300 system from Compal, configured as a complete node for a Blackwell Ultra AI factory. Eight Blackwell Ultra GPUs on the HGX B300 NVL8 baseboard share 2.1 TB of HBM3e over fifth-generation NVLink, and each GPU gets its own 800 Gb/s ConnectX-8 SuperNIC port for the cluster fabric, so the server drops straight into an InfiniBand or Spectrum-X rail design.
It is air cooled, which means it can go into a high-density air-cooled hall without a liquid-cooling loop. Plan for a 10U slot and power and airflow for a system in the region of 14 kW.
