Burst is related to EC2 Performance
Amazon EC2 allows you to choose between Fixed Performance Instances (e.g. M5, C5, and R5) and Burstable Performance Instances (e.g. T3). Burstable Performance Instances provide a baseline level of CPU performance with the ability to burst above the baseline.
New Generation is cheaper as compared to Old/deprecated - if other features stay same.
