====[[Intel 80486SX|80486SX]]====
* Introduced April 22, 1991
* Clock rates:
** 16&nbsp;MHz, 13&nbsp;MIPS
** 20&nbsp;MHz, 16.5&nbsp;MIPS, introduced September 16, 1991
** 25&nbsp;MHz, 20&nbsp;MIPS (12 SPECint92), introduced September 16, 1991
** 33&nbsp;MHz, 27&nbsp;MIPS (15.86 SPECint92), introduced September 21, 1992
* Bus width: 32 bits
* 1.185 million transistors at 1&nbsp;μm and 900,000 at 0.8&nbsp;μm
* Addressable memory 4&nbsp;GB
* Virtual memory 64&nbsp;TB<ref name="Ram2001"/>
* Identical in design to 486DX but without a math coprocessor. The first version was an 80486DX with disabled math coprocessor in the chip and different pin configuration. If the user needed math coprocessor capabilities, they must add 487SX which was actually a 486DX with different pin configuration to prevent the user from installing a 486DX instead of 487SX, so with this configuration 486SX+487SX you had 2 identical CPU's with only 1 effectively turned on
* Officially named Intel486&nbsp;SX
* Used in low-cost entry to 486 CPU desktop computing, as well as extensively in low cost mobile computing
* Upgradable with the [[Intel 80486 OverDrive|Intel OverDrive processor]]
* Family 4 model 2
