Accelerate large-scale AI applications with the new Amazon EC2 P6-B300 instances

Today, we’re announcing the general availability of Amazon Elastic Compute Cloud (Amazon EC2) P6-B300 instances, our next-generation GPU platform accelerated by NVIDIA Blackwell Ultra GPUs. These instances deliver 2 times more networking bandwidth, and 1.5 times more GPU memory compared to previous generation instances, creating a balanced platform for large-scale AI applications.

With these improvements, P6-B300 instances are ideal for training and serving large-scale AI models, particularly those employing sophisticated techniques such as Mixture of Experts (MoE) and multimodal processing. For organizations working with trillion-parameter models and requiring distributed training across thousands of GPUs, these instances provide the perfect balance of compute, memory, and networking capabilities.

Improvements made compared to predecessors
The P6-B300 instances deliver 6.4Tbps Elastic Fabric Adapter (EFA) networking bandwidth, supporting efficient communication across large GPU clusters. These instances feature 2.1TB of GPU memory, allowing large models to reside within a single NVLink domain ...
