Amazon EC2 P6-B300 Instances Available

Starting today, Amazon Elastic Cloud Compute (Amazon EC2) P6-B300 instances are available in the US East (N. Virginia) Region. These instances feature 8xNVIDIA 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 deliver 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. The higher networking and larger memory provide faster training times and more token throughput for AI workloads.

P6-B300 instances are available in the p6-b300.48xlarge size in the following AWS Regions: US West (Oregon), AWS GovCloud (US-East), and US East (N. Virginia).
