How many folks are still running 386 processors? AMD 64 I can see.
i386 refers to the chip architecture of 386, 486 and Pentium - in other words, virtually all Intel chips for the past 20 years.
I still have an AMD Athlon XP 1200 running XP. I use it for usenet and some old games. FF won’t update, and the last K-lite wouldn’t install because of the lack of hw features.
In processor speak, "i386" refers to the standard 32 bit Intel processors, whereas "AMD64" refers to the AMD & Intel 64 bit processors, including XEON. Other processor architectures include Intel Itanium (not seen too much anymore,) IBM Power8, and ARM.
