Intel Spots A 3888.9% Performance Improvement In The Linux Kernel From One Line Of Code

Would this performance boosting line help when using Linux on PS4? I would love to turn my PS4 into a Linux "pc" to use with PC games and Linux Switch emulators.

Well for starters, the PS4 uses AMD.

Edit/correction:
Misinterpreted title to mean Intel CPUs alone.

I have no idea what point you are trying to make.... read the following.

Linux is a Unix-like, open source and community-developed operating system (OS) for computers, servers, mainframes, mobile devices and embedded devices. It is supported on almost every major computer platform, including x86, ARM and SPARC, making it one of the most widely supported operating systems. Also FreeBSD offers optional binary compatibility with Linux, enabling users to install and execute Linux binaries without modification. The architectures i386, amd64, and arm64 are supported. Some Linux-specific operating system features are not yet implemented on FreeBSD.

It's an impressive number but I doubt it. Unless a lot of things were being bottlenecked by this particular aspect of the kernel, there will be no visible improvement. This 3888% performance boost might not even be under real-world conditions, rather just how long it takes to complete this specific benchmarking test.

He thinks the performance boost is related to intel processors - it's not.
It's just that intel has been performance testing parts of the linux kernel, and noticed that a recent change in the linux kernel has made it more performant / efficient.
That change (very likely) applies to any processor, intel is simply behind the testing.

The point is, *any* improvement with this kind of numbers is most likely applicable to very specific workloads on very specific systems. Furthermore, AMD and Intel have very different architectures, and do behave very differently.

Either way -"3000%" improvements are *not* game-changing in the vast majority of cases, so I wouldn't really care too much about this case.

This won't do much in reality for 99.9% of people. Its very few workloads it can be used in
