I believe my first amd was a desktop athlon around 2000. I needed a fast machine to crunch my undergraduate thesis and that was the most cost effective.

In recent years I can’t buy amd for a strong desktop, went with xps and there’s no options. Linux is a requirement for me, so it narrowed down my choices a lot. As you’d expect, it’s a horrible battery life compounded by being forced to pay and not choose an NVIDIA card that also has poor drivers and power management.

x86 and it’s successor amd86 instruction set is a Pandora box and a polished turd, hiding things such as micro instructions, a full blown small OS running in parallel and independent of BIOS, and other nefarious bad practices of over engineering that is at the roots of spectre and meltdown.

What I mean is I prefer AMD over Intel, but I prefer riscv over both.
