A family of earlier upgrade chips from Intel for replacing older 486 chips with faster 486s or Pentium CPUs. In the mid-1990s, separate blue-colored OverDrive sockets were added to some 486 motherboards for future upgrades.
Corporations and individuals who purchased a 120 or 133 MHz Pentium processor or PCs equipped with them between October 23, 1995 and January 5, 1996 are entitled to $50 rebates on the purchase of Intel's new Pentium OverDrive processors, which deliver performance to the level of Intel's more advanced chips with MMX or multimedia capability.
The new Pentium OverDrive processors with MMX technology provide higher levels of processor performance for existing applications and even better performance for media-rich applications designed for Intel's MMX technology.
