		The Intel 80486SX is an Intel 486DX microprocessor with its floating-point unit (FPU) disconnected.
		If testing showed that the central processing unit was working but the FPU was defective, the FPU's power and bus connections were destroyed with a laser and the chip was sold cheaper as an SX; if the FPU worked it was sold as a DX.

		Intel now has a large family of embeddable processors including a 386, a 486, a Pentium, and a Celeron.
		Intel replied with the 80386SX (32 bits internally with a 16 bit data bus capability.) The XX386 chip at 25 MHz was the minimum platform that Windows needed to function as an effective OS.
		Intel soon followed with a 333 MHz version that was snapped up by OEM's and a great rush of sub-$1000 multimedia machines made their way to the 1998 Christmas market.

	[No title]
		While the internals of the Cyrix 486SLC/DLC are roughly equivalent to those in the Intel 80486SX, the bus interface of these chips is identical to that of the Intel 80386DX and 80386SX CPUs, respectively to allow easy replacement of the Intel CPUs by the Cyrix chips.
		The lower performance of the Cyrix 486DLC as compared to the Intel 80486SX is mostly due to the slow 386DX bus interface the 486DLC uses, which is up to 2 times slower than the 486 bus interface.

	Intel 80486SX
		The Intel 80486SX is the same chip as the 80486DX with one exception: the lack of an integrated math coprocessor (floating point unit).
		Note that this is a different kind of difference between the SX and DX versions than is the case with the 386; the 386SX and 386DX both had no coprocessor and the 386SX had narrower data and address buses than the 386DX.
		What Intel wanted people to think was that (like with its earlier coprocessors) you would put the 80487SX in and it would handle the math functions.
