Starting today, Amazon Elastic Cloud Compute (Amazon EC2) P6-B300 instances are available in Asia Pacific (Hyderabad) and South America (Sao Paulo) Regions. P6-B300 instances provide 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.

P6-B300 instances deliver 2x networking bandwidth, 1.5x GPU memory size, and 1.5x GPU TFLOPS (at FP4, without sparsity) compared to P6-B200 instances, making them well suited to train and deploy large trillion-parameter foundation models (FMs) and large language models (LLMs) with sophisticated techniques. The higher networking and larger memory deliver faster training times and more token throughput for AI workloads.

P6-B300 instances are now available in p6-b300.48xlarge size in the following AWS Regions: US West (Oregon), AWS GovCloud (US-East), US East (N. Virginia), Asia Pacific (Hyderabad, Seoul), and South America (Sao Paulo). To learn more about P6-B300 instances, visit [Amazon EC2 P6 instances.](https://aws.amazon.com/ec2/instance-types/p6/)
