Amazon EC2 P6-B300 Instances Now Available

Amazon EC2 P6-B300 instances are now available in the AWS GovCloud (US-East) Region. These instances offer 8x NVIDIA Blackwell Ultra GPUs with 2.1 TB high bandwidth GPU memory, 6.4 Tbps EFA networking, 300 Gbps dedicated ENA throughput, and 4 TB of system memory.

Compared to P6-B200 instances, P6-B300 instances provide 2x networking bandwidth, 1.5x GPU memory size, and 1.5x GPU TFLOPS (at FP4, without sparsity). They are ideal for training and deploying large trillion-parameter foundation models (FMs) and large language models (LLMs) with sophisticated techniques, offering faster training times and more token throughput for AI workloads.
