NVIDIA's Blackwell Ultra B300 systems have arrived with our UK distribution partners. If you have been waiting for the most capable eight-GPU platform NVIDIA makes, the wait is nearly over. You can configure, price and order yours today, without a sales call.
What B300 brings
Blackwell Ultra is NVIDIA's step up from B200, built for the two jobs that matter most right now: training large models and serving reasoning models to many users at once. An eight-GPU HGX B300 system gives you:
- 288 GB of HBM3e on every GPU, over 2 TB in one system. Large models, long contexts and big batches fit in GPU memory instead of being split across machines.
- Up to 144 PFLOPS of FP4 and 72 PFLOPS of FP8 (NVIDIA's sparse figures for HGX B300), for fast inference and efficient training.
- Fifth-generation NVLink at 1.8 TB/s per GPU, so the eight GPUs behave like one very large accelerator.
- 800 Gb/s ConnectX-8 networking per GPU, ready to scale from one node to a full AI factory.
Who it is for
- AI companies and research teams training or fine-tuning frontier-scale models.
- Enterprises serving reasoning models and agents to thousands of staff or customers, on infrastructure they own.
- Data centre and GPU cloud operators adding the newest capacity their customers are asking for.
Configure yours in minutes with the AI Sales Engineer
You don't need to wait for a quote by email. Our AI Sales Engineer knows the B300 platforms in our catalogue, reads their specifications and compatibility rules, and prices every configuration from our live pricing engine. It never quotes a number it didn't get from the catalogue.
- Tell it what you are building: the models, their sizes and precision, how many users, and where the system will live.
- Get a build: GPUs, CPUs, memory, storage and networking, with the trade-offs explained, plus power and rack requirements.
- Get it priced: it can add the system to your basket, create a PDF quote, or take you straight to checkout. You confirm every step.
Prefer to start from the hardware?
