T3 instances also feature the latest 2.5 GHz Intel Xeon Scalable processors which combined with the AWS Nitro System result in up to a 30% better price to performance improvement over T2 instances
T3 instances are powered by the Nitro system. In addition to CPU bursting, they support network and EBS bursting, giving you access to additional throughput when you need it. Network traffic can burst to 5 Gbps for all instance sizes; EBS bursting ranges from 1.5 Gbps to 2.05 Gbps depending on the size of the instance, with corresponding bursts for EBS IOPS.
