Live now · B300 nodes in service
NVIDIA B300, owned by SYNKO, hosted in Australia.
Dedicated Blackwell Ultra capacity for training, fine-tuning and inference. Reserve a single node or a full cluster — run it yourself on bare metal, or let us manage it end to end.

02The network
An NVIDIA-spec fabric, end to end.
Our B300 clusters are networked to NVIDIA’s reference architecture on NVIDIA Spectrum-X Ethernet, designed and run by our operations partner Amaze.
Inside the node
NVLink 5 · 1.8 TB/s per GPU
All eight B300 GPUs in a node share one fifth-generation NVLink domain, so they work together as a single large accelerator.
Between nodes
Spectrum-X · 800 Gb/s per GPU
Every GPU has its own ConnectX-8 SuperNIC, linked over NVIDIA Spectrum-X Ethernet with RDMA (RoCE) for direct GPU-to-GPU transfers across nodes.
Capacity
No oversubscribed paths
Each cluster gets dedicated fabric bandwidth, so throughput stays predictable from one job to the next.
Performance
Tuned for collective ops
Spectrum-X adaptive routing and congestion control keep all-reduce and other collective traffic flowing evenly at multi-node scale.
03Ways to use it
From one node to a full cluster.
GPU clusters
Multi-node clusters linked by high-bandwidth GPU networking, sized for large training and fine-tuning runs.
EnquireModel testing
Short-term access to prove out a model on B300 before you commit to a longer reservation.
EnquireManaged AI operations
We handle provisioning, orchestration, monitoring and lifecycle operations, so your team can focus on the models.
Enquire04Why SYNKO
Sovereign by design.
01
Your data stays in Australia
Workloads run on Australian soil, under Australian jurisdiction.
02
We own the hardware
Our B300 fleet belongs to SYNKO — no resold capacity and no hidden middle layer.
03
Compliance built in
Every customer is screened, and we operate in line with NVIDIA’s requirements and US export controls.
04
Ready for what’s next
Our sites are planned to step up to NVIDIA’s next platform, Vera Rubin, as it becomes available.
