Surely, Magento 2 should require much more hardware resources than Magento 1, because Magento 2 is much more complex and powerful software and there is a 8 years gap between Magento 1 and Magento 2 technologies.
We value all input we get from across the ecosystem. This recently published data differs from what we’ve experienced firsthand and have heard from merchants who are using Magento 2.0 with good results. We’re confident in M2’s performance. We always strive to improve and will continue to invest in enhancing performance, while balancing that with the flexibility and customization Magento is famous for.
This Comparison is true?
