Anyone testing their Xojo windows code and AMD based systems?

General

I pretty much know the answer to this as I know that AMD runs x86 code. I only have Intel based systems and just working if anyone is testing on AMD, and if any issues have been found with AMD vs True Intel x86?

I have run Xojo apps on both Windows and Linux on Intel and AMD CPUs and encountered no differences.

There can be differences when you get to more low-level operations but the Xojo Framework and the OS abstracts all that, for the most part.

That’s my thought exactly. I just wondered if anyone has seen issues with their Xojo apps. I seriously doubt I’d ever be doing anything that would cause incompatibility between AMD and Intel CPUs

I prefer amd over intel, on windows or linux bever had issues with xojo

Occasionally, I write apps for my Steam Deck, which uses an AMD processor. In our office, we have Windows 11 computers with both Intel and AMD processors. We’ve never noticed any difference in the execution of the programs.

Why should there be? AMD processors, as far as I know, fully support the x86 instruction set.

I agree, I was just wondering if anyone has seen any issues. It’s not something I’m concerned about, just my curiosity.

Unless you are somehow integrating machine code into your Xojo application, I seriously doubt there is anything your code can do that could possibly behave differently on AMD vs Intel. There are simply too many layers of abstraction between your uncompiled code and how the resulting compiled application is executed.

Here’s some background on how the Xojo compiler works that you might find illuminating:

AMD owns the x64 instruction set which your 64 bit applications use. They license it to Intel. (intel owned the 32 bit set)

The x64 instruction set, known as x86-64 or AMD64, was developed and is owned by Advanced Micro Devices (AMD), which later licensed the specification to Intel. Intel implemented these extensions under the name Intel 64. This arrangement is part of a complex cross-licensing agreement between the two companies regarding their respective x86 and 64-bit patents

So I think you can be very sure that AMD is more than compatible.
