It seems they don't document the ISA for any instance types. This could be deliberate (and unrelated to marketing) in case they decide to pull features from the instance types in a microcode update. Without any ISA specifics, previous customer commitments towards instance types would still apply.

They list what specific cpus you get for each instance type, see eg https://docs.aws.amazon.com/ec2/latest/instancetypes/gp.html

		The part under “Performance specifications“? That's not really a commitment to functionality, especially since there is no vendor specification (ISA reference manual) for many of those model names given. Intel even published a FAQ about missing specifications: https://www.intel.com/content/www/us/en/support/articles/000...
