This is a good start. Could we start to create a hierarchy of major
architectures next? I propose the following:

i486->Intel->i486
i486->Cyrix->Cx486
i486->AMD->Am486
i486->UMC->Green CPU
i586->Intel->Pentium Classic
i586->Intel->Pentium MMX
i586->Intel->Atom
i586->AMD->K5
i586->AMD->K6
i586->AMD->K6 II
i586->AMD->K6 III
i586->Cyrix->5x86
i586->Cyrix->6x86
i586->Cyrix->6x86MX
i586->Cyrix->Cyrix III
i686->Intel->Pentium Pro
i686->Intel->Pentium II
i686->Intel->Pentium III
i686->Intel->Pentium 4
i686->Intel->Pentium M
i686->Intel->Core 2
i686->AMD->K7
i686->AMD->K8

You would put the computer you tested it on inside one of these directories.

This will need to be edited if you choose to use it. I left out items
I know little about, such as Geode GX1, Geode LX, VIA C3-2, VIA C7,
Transmeta Crusoe and Efficeon, Winchip-2, Winchip-C6, and certainly
others.
