The Kinsta blog has published an article they call the Definitive PHP 5.6, 7.0, 7.1, 72. and HHVM benchmarks providing a comparison between these different versions running different popular PHP software (including WordPress, Drupal and Magento 2).

Each year we try and take a deep dive into performance benchmarks across various platforms and see how different versions of PHP and HHVM stack up against each other. This year we went all out and benchmarked four different PHP engines and HHVM across 20 different platforms/configurations; including WordPress, Drupal, Joomla!, Laravel, Symfony, and many more. We also tested popular eCommerce solutions such as WooCommerce, Easy Digital Downloads, Magento, and PrestaShop.

[...] The results this year have drastically changed from our previous benchmarks where HHVM was the winner. We now are excited to see PHP 7.2 as the leading engine in terms of speed. [...] This is great news for developers and end-users alike as it means more of a focus back on PHP and providing faster websites and web services for everyone.

The post then starts with a look at the system setup (well, Google Cloud instance) that's used for the testing and how it is configured. From there it goes into the test results from each of the different types of software:

• WordPress
• Drupal
• Joomla!
• Magento 2
• Grav CMS
• October CMS
• Laravel
• Symfony
• PyroCMS
• Pagekit
• Bolt
• AnchorCMS
• PrestaShop
• CraftCMS
• ForkCMS

As you can see there's more of a leaning towards content management and e-commerce solutions in their list. It's good to see base frameworks in the list too, however. For each item in the list they provide a graph of the results showing requests per second.
