The following tables and notes constitute an overview of the x86-based processors produced (most of which are still available in some form today). These tables are intended as a guide only, the most reliable way to determine CPU features (amongst newer CPUs at least) is by using [[CPUID]].
The table is fairly easy to read, but a note on some of the values would be helpful. Values marked with '''Yes''' are available in all CPUs in that series, no exceptions. Items marked with '''No''' are not available at all. Items marked with '''Maybe''' are available in some of the CPUs (maybe higher speced machines, for instance the 486DX, or in later processor steppings). Items marked with a '''?''' are yet to be researched or confirmed. If you have some information, let us know!
Most of the information in this table comes from [[Wikipedia:Main_Page|Wikipedia]], with some coming from the Intel and AMD processor manuals.

==Advanced Micro Device Intel-compatible Processors==
The biggest competitor to Intel at this time (2004 August). They came into being slightly after Cyrix with a 5k86 (being a 486 compatible similar to the 5x86, don't confuse them) and then followed it up by a K6 processor. This one was faster than the Pentiums, and more popular than the Cyrix ones because they both didn't rate it (afaik), and they didn't overheat (as was claimed, untrue, for the Cyrixes).
