Ask HN: AMZN Q1 Earnings Today; will spectre mitigations boost earnings?

Spectre / meltdown were mitigated at the beginning of Q1 in January. Reports were that they caused 30% slowdown of many common tasks. Assuming AWS customers were operating servers with <30% headroom, some of those customers needed to upgrade to bigger machines or use more CPU credits. Will this have a noticeable effect on AWS revenue?
