The Pentium OverDrive was a microprocessor marketing brand name used by Intel, to cover a variety of consumer upgrade products sold in the mid-1990s. It was originally released for 486 motherboards, and later some Pentium sockets. Intel dropped the brand, as it failed to appeal to corporate buyers, and discouraged new system sales.
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 OverDrives typically possessed qualities different from 'standard' i486s with the same speed steppings.

Socket 5 was created for the second generation of Intel P5 Pentium processors operating at speeds from 75 to 133 MHz [1] [2] as well as certain Pentium OverDrive and Pentium MMX processors with core voltage 3.3 V. It superseded the earlier Socket 4. It was released in March 1994. [3]
It was an updated Socket 1 with added support for Pentium OverDrive processors. Socket 2 was a 238-pin zero insertion force (ZIF) 19×19 pin grid array (PGA) socket suitable for the 5- volt , 25 to 66 MHz 486 SX , 486 DX , 486 DX2 , 486 OverDrive and 63 or 83 MHz Pentium OverDrive processors.
In Intel's "Family/Model/Stepping" scheme, the Pentium II OverDrive CPU identifies itself as family 6, model 3, though this is misleading, as it is not based on the family 6/model 3 Klamath core. As mentioned in the Pentium II Processor update documentation from Intel, "although this processor has a CPUID of 163xh, it uses a Pentium II ...
The 8088 version, with an 8-bit bus, was used in the original IBM Personal Computer. 186 included a DMA controller, interrupt controller, timers, and chip select logic. A small number of additional instructions. The 80188 was a version with an 8-bit bus. 286 first x86 processor with protected mode including segmentation based virtual memory ...
RapidCAD is a specially packaged Intel 486DX and a dummy floating-point unit (FPU) designed as pin-compatible replacements for an Intel 80386 processor and 80387 FPU. Because the i486DX has a working on-chip FPU, a dummy FPU package (the "RapidCAD-2") is supplied to go in the Intel 387 FPU socket. The dummy FPU is used to provide the FERR ...
