The i486SX was a microprocessor originally released by Intel in 1991. It was a modified Intel i486DX microprocessor with its floating-point unit (FPU) disabled. It was intended as a lower-cost CPU for use in low-end systems—selling for US$ 258—adapting the SX suffix of the earlier i386SX in order to connote a lower-cost option.
The maximal internal clock frequency (on Intel's versions) ranged from 16 to 100 MHz. The 16 MHz i486SX model was used by Dell Computers. One of the few i486 models specified for a 50 MHz bus (486DX-50) initially had overheating problems and was moved to the 0.8-micrometer fabrication process. However, problems continued when the 486DX-50 was ...
An Intel DX2-66 MHz OverDrive An Intel i486SX2-50 MHz OverDrive processor installed next to the original i486SX processor.. Intel's i486 OverDrive processors are a category of various Intel i486s that were produced with the designated purpose of being used to upgrade personal computers.
The cheapest model in the LE range features a 33-MHz i486SX chip, 4 MB of memory, and no built-in hard disk drives (a Fast SCSI controller card was preinstalled, however, for aftermarket hard drive installation; up to four hard drives can be installed internally, with a RAID controller optional).

For the early i486SX in a PGA package, one could flip the lid off the package and. if they had a steady hand and knew which bond pad disabled the FPU, they could disconnect the bondwire to reenable the FPU. They probably could have identified the bond pad by comparing the bond wires of an i486DX and an i486SX on the same process (same die size).
On its release in October 1993, the stock CF-V21P featured an Intel i486SX microprocessor clocked at 25 MHz, initially upgradable to a 50-MHz i486DX2. [3] Later, the company made the i486DX4 clocked at 75 MHz available as a processor upgrade. [4]
