The state of PHP 8.3 and especially 8.4 is a lot better than HHVM. They have diverged quite a lot to a point that it's no longer a drop-in replacement.
PHP added JIT in 8.0, and these math-heavy tasks can take advantage of it. It's not trivial to fine tine JIT configuration though.
In PHP 8.4 (scheduled Nov 2024), there is a major upgrade to JIT as well.
