old t2.micro VS new t2.micro (same type!)

Question

Hello. 
I've created t2.micro few years ago. (+2yr)
****
I was wondering whether or not to replace the instance with **t2.micro** (same type), just newer.

I saw that old and new - have same pricing.

But my question is, do they have same machine power? any other difference?
****
(generally i was considering to change OS, but not really relevant to question)

thanks in advance

Answer

For additional savings look to the t3a.micro for $0.0094/hr in US regions.  Same CPU/memory as the t3.micro but based on AMD CPU rather than Intel.

Answer

There isn't an old and a new t2.micro type, they are the same type.

New generation instance would be a t3.micro (read about the [t3 family](https://aws.amazon.com/ec2/instance-types/t3/))

If you are looking to modernize, you should move to the t3 family from the t2 family. If you are able to migrate your workload to ARM, then have a look at the t4g family.

Price wise, in US regions a t2.micro is $0.0116 per hour on-demand and a t3.micro is $0.0104, so the t3.micro is 91% the price of a t2.micro. Other than being a newer instance type, the t3 family has more predictable burst characteristics than the t2 family.
