That\'s not a general problem. There was a period with the early

It wasn\'t AMD but I recall one processor that ran CP/M and DOS, both
rather poorly. National maybe?
NEC V20
https://en.wikipedia.org/wiki/NEC_V20
And it ran them surprisingly well for the time. I had one. The 16 bit
V30 version was almost as fast as a 286 and had bit twiddling
instructions. V20 was certainly faster than the 8088 by ~10%.
ISTR there was a bun fight over reverse engineered/stolen microcode
too.
The most impressive of the alternative chips was the Cyrix FasMath FPU
which was done by formal methods and found multiple bugs in the Intel
387 implementation of the IEEE floating point standard in the process.
It was about 50% faster and also more accurate which was very
useful in
scientific circles.
Quirks of fate. IBM didn\'t believe in the PC market and the 8088 was the
cheapest way to go. And here we are...
The computer world can be obsessed with compatibility one minute, and
completely ignores it the next. The hardware platform was all about
compatibility for Windows, but Apple was happy porting, and porting
again. They started with 68000 processors, switched to Power PC when
that was a better choice, then switched to Intel when that was a
better choice, all software compatible... well, more or less.
Meanwhile updating your Windows OS will break drivers for printers,
cameras, and on the odd occurrence, applications themselves. New
versions of the OS require you to verify your basic PC hardware is
supported even though they still include the equivalent of the 8253
chip for the real time clock counter, even if it\'s not used.
The only consistency in the computing world is the lack of
consistency, and even that is inconsistent making it consistent. Or
something like that.
You fucking idiot. What makes you think Bowman is in the electronics
group? Learn to use a computer there\'s a dear.
