Talk, Rumors, X Versus Y This article started life when I was asked to write a comparison of x86 and PowerPC CPUs for work. We produce PowerPC based systems and are often asked why we use PowerPC CPUs instead of x86 so a comparison is rather useful. While I have had an interest in CPUs for quite some time but I have never explored this issue in any detail so writing the document proved an interesting exercise. I thought my conclusions would be of interest to OSNews readers so I've done more research and written this new, rather more detailed article. This article is concerned with the technical differences between the families not the market differences.

8080 and 8086 are unrelated

They are neither binary nor source compatible. Their interrupt, memory segmentation/banking, I/O modes are completly unrelated. 8080 is completly hand coded while 8086 uses microcode. 8080 has no complex instructions, 8086 has plenty of them. 8086 is way more complicated than 8080 with 16 bit additions (8080 can use 16 bit adressing with BC, DE or HL register couples, btw.)

IOW, 8086's only relation to 8080 is that both were designed and produced by intel. That is it. Intel might have said 8086 extends their midrange to 16 bit, which was established by 8080 but technically, they are completly unrelated CPUs even designed by different people (original 8080 designers left to found Zilog) and philosophy.

Who is dumbass now?
