What is an Apple computer? Is there any difference between it and my AMD Sulong computer?

Apple in the usual sense.

The main difference with your machine is:

Apple is a brand machine; And it doesn't use Windows, but Apple's own macOS; It uses RISC reduced instruction set processors (previously IBM's Power series processors), which are far more efficient than Intel and AMD's CISC complex instruction sets in terms of graphics processing; Only use software that is written specifically for macOS.

Apple is the brand!

One-sided hardware is not the same! The system is Apple's Mac

Apple's computer is self-contained, hardware, software is all for mac, generally incompatible with Windows, generally Apple's computer is used for graphic design, ** with professional machines.

Now it's a little better, Apple is starting to use Intel's CPU, probably installing Windows.

AMD Athlons means that your computer's CPU is powered by the Athlon series of CPUs produced by AMD

The CPU of Apple computers used to be customized, neither Intel, nor AMD, I don't know much about other hardware, and the operating system used by Apple computers is Apple Mac system, not Windows XP and the like that we commonly use.

Also, the XP system doesn't seem to be able to be installed on Apple computers.

Everything in Apple is self-contained. It is suitable for drawing, and it is unique in terms of processing power and efficiency for graphics. The operating system and accompanying software of the Mac are not the same as the computer you are using now, so don't consider it if you don't have special needs.

In fact, many people criticize Apple's approach, but their tradition has always been like this. Of course, their market share is also very low, so they were also on the verge of bankruptcy. But in the end, they survived because of their unique advantages.

In fact, Apple has a good relationship with Intel or AMD, but now Apple's CPU uses Intel Luzao products, and graphics cards use AMD products, but according to the current situation, I don't think Apple will use AMD's CPU in the short term, mainly for the following reasons:

1. Apple has been using the Thunderbolt interface for many years, and the dependence is quite high, and the Thunderbolt interface is Intel's authorization and technology, so if you switch to AMD processors, then the configuration of the Thunderbolt interface will naturally be affected, which will directly affect the experience of using Apple computers.

2. Over the years, AMD's CPU has been unsatisfactory in terms of performance and efficiency, and it has only been a matter of these two years to catch up with Intel, but Apple's system and software have long been optimized for Intel CPU, if you immediately switch to AMD processors, then the actual performance may still lag behind, including Intel's brand awareness is also much higher than AMD, and switching to AMD will affect consumers' choices.

3. AMD does not have its own factory, and its production capacity is limited by the foundry. The demand for CPUs is much higher than that of graphics cards, take AMD's third-generation Ryzen as an example, the high-end 3900X has been out of stock for a long time, and this is only the retail market, if there are big customers like Apple, it is obviously impossible to meet the demand. And Intel, because it has its own factory, is much better in terms of volume.
