De-merits in using Cortex A9 for single core processor

Hi Experts,

A8 is meant for single core and A9 is for multi-core based.

Consider in case of SoC is build with single core of A9 and A8 how we could compare both in terms of some metrics/parameters like power/speed ?

  • The Cortex-A8 is I think the oldest member of the Cortex-A family and has slipped from their current portfolio as something else will always be better for anything (though I'm sure they'll always licence you anything if you ask!). As you say a decision is complicated, but you'll have a minimum speed requirement and a power requirement and can work from there. Wikipedia have a little table which gives some basic details of the differences between the cores but doesn't indicate their design maximum frequencies or power.
