Does programming (JavaScript, PHP, etc.) benefit more from multicore or single-core performance?

I'm referring to the Laptop 4000 Gen, which has only been released recently. It should have 90 percent more power than the current Intel laptop processors.

It depends on what you program and how. Most programs, however, benefit more from single core performance than multicore. Unless of course you work with multithreading.

When programming, the programmer is usually the limiting factor. Whether the end result benefits from the higher processor performance is a question of the end result. With PHP / JavaScript this increase in performance will probably hardly be noticeable. What could be faster would be the combination Apache / PHP-FPM, because here several processes for PHP are spawned and run in parallel. But whether that makes the cabbage fat…

But now seen in theory.

I added a "could" case to the answer.
