n/w performance and Clock Speed -  may stay same  in a instance family.

Instance Family : Processor Speed /N.W Performance:  a1,t2, t3 [General Purpose]          c4, c5 [Compute Optimised]                   [Memory Optimized/RAM]           [Accelerated Computing/HW Accelerator]     [Storage Optimized/EBS]

Large has 4GB RAM, 1 Core, 2 VCPUs

similarly, xlarge has 8 GB RAM, 2 Core, 4 VCPUs

n/w performance and Clock Speed -  may stay same  in a instance family.


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.
