Not sure why you're being downvoted, yeah cookies are handled by legislation other than GDPR (ePrivacy as you mentioned).

However regardless of whether you're using cookies, I still think you need to collect explicit consent as GDPR requires a lawful basis of processing, and I don't see how analytics would fall under any of the other lawful basis's other than consent (_maybe_ legitimate interests?)

If you are using cookies, then my understanding is you need to collect consent where necessary under _both_ ePrivacy and GDPR.
