This Pentium OverDrives are Intel Pentium processors for 486 Socket 3 and Socket 2 motherboards, provided as a means to give a Pentium performance-level upgrade option for owners of 486 computer systems. It was however criticised for being more expensive and slower than competing CPU-upgrade options such as the AMD Am5x86 and Cyrix 5x86, and being too late to the market. Mainboard compatibility was also a problem, it turned out that many boards didn't support this new chip.
 
To perform properly, the Pentium OverDrive was dependent on a high amount of secondary cache ram being present on the motherboard; without it the chip was only a trivial amount faster than a DX4.

The original Pentium P5 chips were different than later P54 versions, in terms of voltage, socket size and power consumption. Intel made a clock-doubling OverDrive for these chips, which is sold as one 120/133 MHz chip: when replacing a Pentium 60 it runs at 120 MHz, and when replacing a 66 it runs at 133. This is a true Pentium chip since it is on a Pentium motherboard, although it still benchmarks below the real Pentium 120/133, most likely due to the older design of the Pentium 60/66 motherboards.

Pentium 75, 90 and 100 MHz run with a clock multiplier of 1.5 on system buses of 50, 60 and 66 MHz respectively. Intel has made OverDrives for these running at 125, 150 and 166 MHz by using a clock multiplier of 2.5.

With the introduction of the Intel Pentium with MMX Technology, Intel also created OverDrive processors to upgrade existing Pentium motherboards to the new MMX chip. Most older Pentium motherboards cannot handle the new Pentium with MMX because of its requirement for a 2.8V core. Keeping with the tradition of Intel's OverDrive line, the Pentium with MMX OverDrive includes a converter that lets it run in Socket 5 motherboards (except for the 200) and Socket 7s that do not have 2.8V support. Otherwise the chip is identical to the standard Pentium with MMX.
