Update from iOS 16 to 17

An iPhone 8, iPhone 8 Plus, or iPhone X isn't capable of 17 or above; they require an A12 or better CPU. Try downloading those applications to a newer unit on the same Apple ID first.

If you have iOS 18, you do not have an iPhone X. iOS 16 is the end of the line for the iPhone X.

The iPhone XS, XS Max, and XR can run iOS 18. Maybe you have one of these phones. They have model names that are very similar to that of the iPhone X, but what matters is the hardware inside. Where the X has the Apple A11 Bionic chip, those three have the A12 Bionic chip, and two of them also have more RAM than the X does.

It's a hardware component not available for that model.

You cannot download a CPU. It is hardware – a chip. The chip inside your iPhone is an Apple A11 Bionic CPU and there is no way to replace it with a different one. The only way to get a newer one is to get a newer phone.

Are you selling it

No, I am not a seller of iPhones. I currently have no plans even to sell mine. However, if you are in the market for an iPhone, Apple would probably be willing to sell you one.
